Which Highway Code rules govern UK motorways?

Motorway driving is covered by rules 253 to 277 of the Highway Code. Rules 253 to 265 cover general motorway driving - who may use the motorway, signs and signals, joining behaviour, lane discipline, overtaking and the prohibition on reversing, U-turns and driving against the traffic flow. Rules 266 to 273 cover joining and leaving the motorway via slip roads. Rules 274 to 277 cover breakdowns, the use of the hard shoulder where one exists, the stranded-vehicle protocol on All Lane Running smart-motorway sections, and the duties of drivers approaching an incident. Breaches of these rules are admissible in any civil or criminal proceedings under section 38(7) of the Road Traffic Act 1988 to establish liability.

What is the difference between motorway accident recovery and a motorway accident claim?

Recovery is the operational job of getting a damaged vehicle off a live motorway carriageway safely under National Highways and police direction - covered separately on the /motorway-accident-recovery page. A motorway accident claim is the legal and insurance process that follows: liability investigation, evidence preservation against gantry CCTV and the National Highways incident log, independent engineer instruction, like-for-like credit hire under Lagden v O'Connor [2003] UKHL 64, personal-injury work through the Official Injury Claim portal or an SRA-regulated solicitor depending on severity, and final recovery of all costs from the at-fault driver's insurer. The two workstreams overlap on day one - the recovery operator's PAS 43 movement record becomes evidence in the claim - but are separately regulated.

Who are National Highways Traffic Officers (HATOs) and what powers do they have?

National Highways Traffic Officers - known as HATOs or Highways Officers, and previously badged Highways Agency Traffic Officers when the agency was the Highways Agency, then Highways England - patrol the English motorway and trunk-road network on behalf of National Highways. They operate under Part 5 of the Traffic Management Act 2004 (sections 6 to 21), which gives them statutory powers to stop and direct traffic, close lanes and carriageways, place temporary signs and signals, manage incidents and request information. Section 6 establishes the role; section 7 sets out the power to direct traffic; section 9 covers powers in relation to vehicles on the strategic road network. HATOs do not have police powers of arrest but operate alongside the police at every serious incident.

What is the rolling block and when do National Highways use it?

A rolling block is a controlled-speed slow-down of all traffic on a stretch of motorway, performed by a National Highways patrol vehicle (or a police vehicle) weaving across the lanes ahead of the incident scene. The traffic behind the patrol vehicle is held at a slow speed, opening a gap in front into which the incident scene can be safely managed - debris cleared, vehicles recovered, casualties attended. The rolling block is the standard live-lane scene-management technique on UK motorways. It is authorised under the HATO direction powers in section 7 of the Traffic Management Act 2004 and runs alongside any police scene management.

What is smart-motorway All Lane Running (ALR) and how does it affect a claim?

All Lane Running is the smart-motorway design in which the former hard shoulder is permanently converted to a fourth running lane. ALR has been in operation since the 2014 M25 J5-7 and M6 J10A-13 schemes and has been retained on existing stretches following the 15 April 2023 Department for Transport decision to cancel all new smart-motorway schemes. On an ALR section there is no hard shoulder available for a routine breakdown - the stranded-vehicle protocol under Highway Code rule 275 therefore points drivers to Emergency Areas (the orange-surfaced refuges placed at intervals along the carriageway) rather than to the verge. A collision file on an ALR section turns on whether a stationary or slow-moving vehicle was struck in a live running lane and whether the Red X gantry signal was set in time.

What was Dynamic Hard Shoulder (DHS) and is it still in use?

Dynamic Hard Shoulder was the earlier smart-motorway design under which the hard shoulder was opened to traffic only during peak periods, when overhead gantry signs activated lane 1. The original M42 Active Traffic Management pilot in 2006 used DHS. Following the Department for Transport's 15 April 2023 announcement, no new DHS schemes are being built and the design is closed for new construction. Existing DHS sections were already being progressively converted to All Lane Running before the announcement. On a DHS section the liability question on a hard-shoulder collision turns on whether lane 1 was open or closed at the moment of impact - gantry signal data is the conclusive evidence and is recoverable from National Highways inside the standard retention window.

What is a Red X and how is it enforced?

A Red X is the overhead gantry signal that closes a motorway lane to traffic. When the lane shows a red X the lane is closed - either because of a stranded vehicle, an incident, debris, lane works or emergency-services activity ahead. Driving in a closed lane is an offence under regulation 9 of the Motorways Traffic (England and Wales) Regulations 1982 (SI 1982/1163), and from June 2019 National Highways has operated automatic ANPR-based detection of Red X transgressions, with the resulting evidence passed to the police. The fixed penalty is £100 with three penalty points; the court-imposed maximum is significantly higher. On a claim file a driver who continued under a Red X faces a near-conclusive contributory-negligence finding and frequently a 100/0 split.

How long does National Highways retain gantry CCTV after a motorway collision?

National Highways operates a network of traffic CCTV cameras on the motorway and trunk-road network - gantry-mounted at smart-motorway sections, pole-mounted elsewhere - feeding the Regional Operations Centres. The standard retention period is typically 31 days unless a recording is flagged for incident review, after which it is held against the relevant National Highways incident log (the HEA / National Highways Agency log). A preservation request submitted promptly via the National Highways customer-contact route, or via the police where the police attended, secures the footage. A request sent after 31 days where the recording was not incident-flagged is usually met with a deletion-already-occurred response. CityGrip drafts the preservation request at intake on every motorway file.

What is the stranded-vehicle protocol under Highway Code rule 275?

Highway Code rule 275 sets the protocol for a vehicle stranded on a UK motorway. Where a hard shoulder is available the driver should pull onto it, switch on hazards, leave the vehicle by the nearside door, walk behind the safety barrier and call 999 or use the orange SOS phone. Where the stretch is All Lane Running and no hard shoulder is available the driver should aim for the next Emergency Area, set hazards on approach and use the SOS phone in the Emergency Area to alert the Regional Operations Centre - which can then set a Red X over the lane the vehicle stopped in. Where the vehicle cannot reach an Emergency Area, occupants should stay in the vehicle with seatbelts on and hazards activated if it is unsafe to exit. The risk of a secondary collision from a following vehicle is the dominant safety concern on every motorway breakdown.

What evidence wins a UK motorway accident claim?

Five categories of evidence dominate motorway files. First, dashcam footage from any vehicle in the immediate area - front-facing, rear-facing and where present cabin-facing - captures the impact, the approach speeds and the lane configuration at the moment of collision. Second, National Highways gantry CCTV from the Regional Operations Centre, recoverable inside the standard 31-day window. Third, the National Highways incident log (HEA log) - a timestamped operational record of every action taken at the scene by HATOs, including any Red X activation and any lane closure. Fourth, telematics and event-data records from modern vehicles - Volvo, Tesla, BMW, Mercedes-Benz and Polestar all retain Intelligent Driving Data event records that include speed, brake application, steering angle and lane-departure-assist activations. Fifth, police accident report (Form 17 / TC1 / equivalent) where the police attended.

Do motorway injury claims go through the Official Injury Claim portal?

Lower-value motorway injury claims do - soft-tissue injuries (whiplash and associated psychological injury) under £5,000 in general damages run through officialinjuryclaim.org.uk under the Civil Liability Act 2018 small-claims regime. The fixed tariff under the Whiplash Injury (Amendment) Regulations 2025 (SI 2025/615) applies for accidents on or after 31 May 2025. The portal is not the right route for higher-severity motorway injuries - the high impact energies on UK motorways routinely produce orthopaedic injury, traumatic brain injury, spinal injury and complex psychological harm that take the claim well above the small-claims limit. Those claims sit outside the portal and proceed through an SRA-regulated solicitor on the standard fast-track or multi-track route.

What happens if I am struck on the hard shoulder of a UK motorway?

Hard-shoulder collisions are a recognised high-severity pattern. A vehicle stopped on the hard shoulder is struck by a vehicle that has either drifted out of lane 1 (fatigue, distraction, mobile-phone use), failed to anticipate the stationary vehicle, or has itself lost control after a debris strike or a tyre failure. The contemporaneous reconstruction turns on dashcam footage from the moving vehicle (where present), National Highways gantry CCTV, the HEA incident log, witness statements from other drivers, and the vehicle damage pattern - a rear-impact collision on the offside of a stopped vehicle establishes a different fault profile from a near-90-degree side impact. CityGrip pulls every available evidence stream inside the National Highways retention window.

How long do I have to bring a UK motorway accident claim?

Three years from the date of the accident or the date of knowledge for any personal injury claim, under section 11 of the Limitation Act 1980. Six years from the date of the accident for vehicle damage and other property loss, under section 2 of the same Act. Where the injured person was a child at the time, the three-year clock starts on the eighteenth birthday. Where the injured person is a protected party under the Mental Capacity Act 2005, the limitation period does not run while the protection continues. Where the at-fault vehicle is uninsured or untraced, the Motor Insurers' Bureau Uninsured Drivers' Agreement 2015 and Untraced Drivers' Agreement 2017 carry their own short notification windows that must also be met. CityGrip records the relevant limitation dates on every file at intake.

UK motorway accident claims

Motorway collisions in the UK turn on a tight set of facts - which lane the vehicle was in, whether the section was conventional, Dynamic Hard Shoulder or All Lane Running, whether a Red X was set, whether an Emergency Area had been reached and what the HATO patrol logged at the scene. This page sets out the claim-side rules, the recurring patterns and the evidence chain. The companion recovery-side page sits at /motorway-accident-recovery.

What should I do after a UK motorway accident?

Get every occupant behind the safety barrier under Highway Code rule 275. On an All Lane Running smart-motorway section, aim for the next orange Emergency Area before stopping; if you are stranded in a live running lane and cannot be moved, stay in the vehicle with seatbelts on and hazards activated. Call 999 or use the orange SOS phone to request a Red X over the closed lane. Once safe, exchange details under section 170 of the Road Traffic Act 1988 and capture the police incident reference. Back up the dashcam clip within 24 hours, request your vehicle's manufacturer event-data, and send a preservation request to National Highways for the gantry CCTV and the HEA incident log inside the 31-day retention window. Then open the accident-management file. For higher-severity injuries the claim goes outside the OIC portal to an SRA-regulated solicitor with your separate written consent.

UK motorway accident claims sit at the high-severity end of the road-traffic claim spectrum. The combination of 70mph national speed limit traffic, multi-lane carriageways, smart-motorway All Lane Running geometry and rapid HATO and police scene management produces a distinct evidence chain - National Highways gantry CCTV, the HEA incident log, ANPR Red X enforcement, vehicle event-data records and dashcam footage all carry more weight on a motorway file than on any other collision scenario. This page covers the claim side: the rules of Highway Code 253 to 277, the statutory powers of National Highways Traffic Officers under Part 5 of the Traffic Management Act 2004, the smart-motorway design changes since the Department for Transport's 15 April 2023 announcement, the recurring collision patterns, the evidence preservation windows and the route into a CityGrip file. The recovery-side operational page sits separately at /motorway-accident-recovery.

Highway Code rules 253 to 277 - the motorway rule set

The Highway Code motorway rules run from 253 to 277. Rules 253 to 265 cover general motorway driving - who is permitted to use the motorway (rule 253 excludes pedestrians, holders of provisional car licences before a relevant supervised lesson, certain agricultural vehicles, motorbikes under 50cc, ridden horses and certain invalid carriages), signs and signals on motorways (rule 257), lane discipline (rule 264 - keep to the left-hand lane when there are no slower vehicles to overtake), overtaking (rule 268 - do not overtake on the left except in specified circumstances) and the prohibition on reversing, U-turns and driving against the traffic flow (rule 263).

Rules 266 to 273 cover joining and leaving the motorway via slip roads - give way to traffic already on the motorway, match speed in the slip-road acceleration lane, signal and adjust position, and on leaving the motorway signal well in advance and use the deceleration lane. Rules 274 to 277 cover breakdowns and incidents - the stranded-vehicle protocol under rule 275, the duties of drivers approaching an incident under rule 283, and the requirements not to slow down to look at an incident in the opposing direction. The Highway Code is statutory and advisory; breaches are not themselves criminal offences but are expressly admissible in any civil or criminal proceedings under section 38(7) of the Road Traffic Act 1988 to establish liability - the same statutory bridge that operates on every other collision scenario.

National Highways Traffic Officers (HATOs) and the Traffic Management Act 2004 Part 5

Traffic Officers on the English strategic road network - known operationally as HATOs and previously branded as Highways Agency Traffic Officers and then Highways England Traffic Officers - operate under Part 5 of the Traffic Management Act 2004 (sections 6 to 21). Section 6 establishes the designation of a traffic officer by the appropriate national authority. Section 7 gives traffic officers the power to direct traffic, including to stop traffic and to direct it to follow a specified route. Section 9 sets out powers in relation to vehicles - to move or arrange the movement of a vehicle on the strategic road network where it is causing an obstruction or a danger.

HATOs do not hold police powers of arrest or stop-and-search. Their authority is statutory direction of traffic and scene management - they close lanes, set up a rolling block, manage debris, attend to broken-down vehicles and coordinate with the police, the fire and rescue services and the ambulance service at the scene. The rolling block - a controlled-speed slow-down of all traffic on a stretch of motorway by a patrol vehicle weaving across the lanes ahead of the scene - is the standard live-lane scene-management technique. On a claim file, the HATO record of events captured in the HEA incident log is a routine evidence pull. The log records every action taken at the scene with second-level precision: time of arrival, time of lane closure, time of Red X activation, time of rolling block start, time of vehicle recovery, time of scene clearance. Where liability is contested, the HEA log is often the determinative document.

The same Part 5 framework applies (with modifications) on the trunk-road network in England. Scotland's motorway network - the M8, M9, M73, M74, M77, M80, M90 and M898 - is operated by Transport Scotland under separate Scottish primary legislation, and Wales's motorways (the M4 between Magor and Pont Abraham and the A55 expressway sections) sit under Welsh Government control. The HATO equivalents in those jurisdictions operate under broadly analogous powers; the underlying Highway Code rules 253 to 277 apply on a UK-wide basis.

Smart motorways - All Lane Running, Dynamic Hard Shoulder and the 15 April 2023 cancellation

Smart motorways evolved through three generations. The original 2006 Active Traffic Management pilot on the M42 between J3A and J7 opened the hard shoulder to traffic during peak periods only - the original Dynamic Hard Shoulder design. From the mid-2010s, new smart-motorway sections on the M25 J5-7, M25 J23-27 and other corridors adopted All Lane Running (ALR), in which the former hard shoulder is permanently converted to a fourth running lane and breakdowns are accommodated in orange-surfaced Emergency Areas placed at intervals along the carriageway. The third element was variable mandatory speed limits set by the gantry signs and enforced by ANPR-fed automatic detection.

On 15 April 2023 the Department for Transport announced that all new smart-motorway schemes would be cancelled. Existing ALR stretches were retained - the cancellation applied to schemes not yet started or only in early stages - and the Emergency Area retrofit programme on existing ALR stretches continued, reducing inter-Emergency-Area spacing across the network. The DHS design was closed to new schemes from the same announcement and existing DHS sections were already being progressively converted to ALR. The practical effect on motorway claim files is that the smart-motorway geography is now stable - the existing ALR sections will remain ALR, the M42 ATM pilot stretch operates as it has done, and no new ALR or DHS conversions are being constructed. A liability file on an ALR section therefore still needs to analyse Red X state, gantry sign content and Emergency Area proximity at the moment of impact. A liability file on a conventional motorway section still needs to analyse hard-shoulder positioning under rule 275 and any tyre-debris or stranded-vehicle pattern that preceded the collision.

Red X enforcement, variable mandatory speed limits and the gantry sign record

The Red X is the overhead gantry signal that closes a motorway lane to traffic. Driving in a Red X-closed lane is an offence under the Motorways Traffic (England and Wales) Regulations 1982 (SI 1982/1163) - specifically regulation 9 and the related signs-and-signals regime. Automatic ANPR-based detection of Red X transgressions has been operational across the National Highways network from June 2019. The fixed penalty is £100 with three penalty points; the court-imposed maximum runs higher. On a civil claim the relevance is direct: a driver who continued under a Red X faces a near-conclusive contributory-negligence finding and frequently a 100/0 split against them, with the gantry signal data and the HEA incident log forming the contemporaneous record.

Variable message signs on the gantry network display lane closures, incident warnings, variable mandatory speed limits and operational messages. The variable speed limits - typically 60mph, 50mph or 40mph stepped down from the 70mph national limit - are mandatory on smart-motorway sections when displayed in red circles, and are enforced by ANPR-fed average-speed detection. On a claim file the content of the relevant VMS at the moment of impact is recovered from National Highways alongside the gantry CCTV. Where the file involves a high-speed collision in a 50mph or 40mph variable-limit section, the speed-of-impact analysis turns on whether the driver was complying with the displayed limit; a breach of the limit is admissible both in any criminal prosecution and in the civil apportionment.

Stranded-vehicle protocol - rule 275 and the All Lane Running variation

Highway Code rule 275 sets the stranded-vehicle protocol. On a conventional motorway with a hard shoulder, the driver should pull onto the hard shoulder, switch on hazards, leave the vehicle by the nearside door, walk behind the safety barrier and call 999 or use the orange SOS phone. The dominant safety concern is the secondary collision - a following vehicle drifting out of lane 1 striking either the stationary vehicle or any occupant who has stepped out into the lane. Department for Transport casualty data has historically identified hard-shoulder secondary collisions as a significant proportion of motorway fatalities and the Highway Code rule reflects that risk.

On an All Lane Running section there is no hard shoulder available for routine breakdowns. The rule 275 protocol points drivers to the nearest Emergency Area, with the inter-Emergency-Area spacing on retrofitted ALR sections progressively reduced through the National Highways retrofit programme. Where the vehicle cannot reach an Emergency Area, the rule advises that occupants should stay in the vehicle with seatbelts on and hazards activated if it is unsafe to exit, and call 999 - the Regional Operations Centre can then set a Red X over the lane the vehicle stopped in to protect the occupants. Exiting a stationary vehicle into a 70mph running lane is the highest-risk action available to a stranded driver and is the dominant cause of secondary-collision fatalities on smart motorways. Files arising from a stranded-vehicle scenario therefore turn heavily on the timing of the Red X activation, the proximity of the next Emergency Area and the content of the gantry signs in the seconds before impact.

02MOTORWAY

Joining and leaving the motorway - rules 266 to 273 and the slip-road merge

Highway Code rules 266 to 273 cover joining and leaving the motorway via slip roads. On joining, the driver gives way to traffic already on the motorway under rule 259, matches speed in the slip-road acceleration lane, signals and adjusts position, and merges into a gap in lane 1 without causing a vehicle on the motorway to brake or swerve. On leaving, the driver signals well in advance (rule 272), uses the deceleration lane and adjusts speed appropriately. A recurring liability pattern on UK motorway files is the slip-road merge collision - a vehicle on the acceleration lane merging into lane 1 strikes a vehicle already in lane 1 that was unable or unwilling to move to lane 2. The apportionment turns on whether the merging driver had a safe gap, whether the lane-1 driver could safely have moved over, and whether either driver had signalled.

On large UK motorway interchanges - the M25 J15 with the M4, the M25 J28 with the A12, the M6 J6 Spaghetti Junction in Birmingham, the M1 J6A with the M25, the M4 J20 with the M5 at Almondsbury, the M62 J35 with the A1(M) at Ferrybridge, the M62 J6 with the M57 in Liverpool - the slip-road geometry is complex and lane allocations change between approach and merge. Liability disputes on these interchanges routinely require gantry CCTV from multiple cameras to reconstruct the relative positions of every vehicle in the seconds before impact. National Highways CCTV is recoverable inside the standard 31-day retention window and CityGrip drafts the preservation request at intake.

MOTORWAY

Section 3 of the walkthrough.

Recurring UK motorway collision patterns

Motorway files cluster around seven recurring patterns. The first is the hard-shoulder collision - a vehicle stopped on the hard shoulder of a conventional motorway is struck by a vehicle that has drifted out of lane 1 through fatigue, distraction or mobile-phone use. The second is the live-lane stranded vehicle impact on an All Lane Running section, where a vehicle stopped in a running lane (typically because it could not reach the next Emergency Area) is struck by following traffic before a Red X is set. The third is the Red X transgression file, where a driver continued in a closed lane and either struck or was struck by a vehicle, recovery or emergency-services activity in that lane.

The fourth is the lane-change side-swipe at motorway speeds, where two vehicles in adjacent lanes attempt to occupy the same space - covered in more detail on the sibling lane-change-accident-claims page. The fifth is the tyre-debris or dropped-load secondary impact, where a vehicle strikes debris in the carriageway or is struck by a vehicle ahead that has lost its load. The sixth is the slip-road merge collision under rules 272 and 273. The seventh - and the highest-severity end of the spectrum - is the multi-vehicle pile-up, where an initial collision precipitates a chain reaction through following traffic, amplified in fog, sun-strike or heavy rain conditions. The M5 carriageway collisions in fog, the M40 corridor pile-ups and the M62 transpennine winter events all feature in the recurring claim pattern.

Across all seven patterns the impact energies on a UK motorway are high. Whiplash-band soft-tissue injury under £5,000 in general damages - within the Civil Liability Act 2018 small-claims tariff and routed through the Official Injury Claim portal - is common at the low-severity end, but motorway files routinely produce orthopaedic, spinal, traumatic brain and complex psychological injuries that take the claim well outside the portal and into the standard fast-track or multi-track litigation route. The secondary-collision risk on every live-lane breakdown is the single largest cause of fatality on the UK strategic road network and the rule 275 protocol is calibrated against it.

04MOTORWAY

Evidence - gantry CCTV, HEA log, vehicle telematics and dashcam

Five categories of evidence dominate UK motorway claim files. The first is National Highways traffic CCTV - gantry-mounted on smart-motorway sections, pole-mounted elsewhere - fed to the Regional Operations Centres. The standard retention period is around 31 days unless the recording is flagged against an incident, after which it is held against the HEA log. A preservation request submitted promptly through the National Highways customer-contact channel, or through the police force handling the scene, secures the footage. Where the file involves a serious injury, the police usually request the gantry footage as part of their investigation and that request preserves the recording for as long as the police hold the file.

The second is the HEA incident log - the timestamped operational record kept by the Regional Operations Centre. Every HATO action is logged with the time to the second, alongside the time of every Red X activation, lane closure and rolling block. The log is the most reliable contemporaneous record of the scene and is routinely determinative on contested liability files. The third is dashcam footage - front-facing, rear-facing and where present cabin-facing - capturing the impact, the approach speeds and the lane configuration. Most dashcams in continuous-recording mode loop their oldest footage within 12 to 48 hours; the clip must be extracted and backed up within 24 hours of the incident.

The fourth is vehicle event-data. Modern Volvo, Tesla, BMW, Mercedes-Benz, Polestar and Audi vehicles retain Intelligent Driving Data event records that include speed, brake application, steering inputs, lane-keeping assist activations and the state of any active-safety system in the seconds before impact. The data is requestable through the manufacturer's data-subject access route under UK GDPR. The fifth is the police accident report - Form 17, TC1, or the regional equivalent - where the police attended. Police reports are disclosable on a third-party motorway file under the Civil Procedure Rules disclosure framework. CityGrip routes the evidence chain at intake so every relevant stream is preserved inside its retention window.

The UK motorway claim process - recovery, engineer, injury route and settlement

The process on a UK motorway claim mirrors any other UK road-traffic claim with three motorway-specific overlays. Step one is the immediate scene response - get behind the safety barrier under rule 275, section 170 exchange where it is safe to do so, police reporting, dashcam back-up and vehicle telematics request. Step two is the accident-management instruction - PAS 43 recovery from the live carriageway (handled in operational detail on the motorway recovery page), secure storage, independent engineer instruction, ABI Salvage Code categorisation (Cat A, B, S or N) and like-for-like credit hire under Lagden v O'Connor [2003] UKHL 64 with the like-for-like principle confirmed in Bee v Jenson [2007] EWCA Civ 923. Notification to the driver's own insurer for information purposes follows.

Step three is the property-damage claim against the at-fault driver's insurer under section 151 of the Road Traffic Act 1988. The third-party insurer's liability investigation on a clear motorway file takes between two and six weeks; where Red X transgression, hard-shoulder positioning or lane-change apportionment is contested, the investigation can run materially longer and benefits directly from a complete National Highways evidence pack. Step four is the personal-injury route. For soft-tissue whiplash-band injury under £5,000 in general damages, the claim runs through the Official Injury Claim portal under the Civil Liability Act 2018 and the Whiplash Injury (Amendment) Regulations 2025 (SI 2025/615). The fixed tariff applies only to soft-tissue injury lasting under 24 months. For higher-severity injuries - orthopaedic, spinal, traumatic brain, complex psychological - the claim sits outside the portal and is referred to an SRA-regulated panel solicitor under CMCOB 6 and CMCOB 7, with the referral arrangement disclosed in writing and the customer's separate written consent recorded.

Step five is settlement and recovery of the credit-hire, repair, storage and engineer costs from the at-fault insurer. Step six is the signed file closure with the CMCOB 4.3.1R(1A) standalone disclosure recorded, the charge schedule provided to the customer in writing and any onward solicitor handling complete. Insurer dynamics on motorway files differ from urban-collision dynamics - high-severity files frequently sit outside the OIC portal from the outset and the at-fault insurer's reserve is set higher early in the file. The Civil Liability Act 2018 tariff applies only to the soft-tissue element below 24 months; everything else is valued conventionally on Judicial College Guidelines and the relevant case law.

This motorway claims page sits under the UK collision-types hub and alongside the sibling Wave-2 and Wave-3 scenario pages. The companion recovery-side page at /motorway-accident-recovery covers the operational PAS 43 recovery workstream from the live carriageway - a distinct workstream from the claim itself but tightly coupled on day one. Cross-vertical hubs for multi-vehicle pile-ups, fog-driving collisions and lane-change side-swipes deepen the relevant patterns at the high-severity end of the motorway claim spectrum.

Ranking factors

Six UK motorway claim-strength factors

The six factors that distinguish a strong UK motorway collision claim from a weak one. Adapted from the universal collision factors with motorway-specific evidence (National Highways gantry CCTV, the HEA incident log, vehicle event-data) and statute references (Traffic Management Act 2004 Part 5, the Motorways Traffic Regulations 1982 and Highway Code rules 253-277). CityGrip handles each file on a claim-by-claim basis, not by scenario template.

Immediate action in the first 72 hours

Motorway files turn on a tight window of perishable evidence. Dashcam footage loops within 12 to 48 hours, National Highways traffic CCTV is retained for around 31 days unless flagged, and the National Highways incident log records every HATO action at the scene with second-level precision. The first 72 hours are when scene photographs, dashcam exports, vehicle telematics requests, the section 170 RTA 1988 exchange and the police reference number are captured. A file built inside that window is materially stronger than one assembled weeks later.

Window: 0-72 hours

UK process fit and statute reference

A UK motorway claim pleads the Road Traffic Act 1988 (sections 143, 151, 170), the Traffic Management Act 2004 Part 5 (HATO powers), the Highway Code (rules 253 to 277, admissible under s.38(7) RTA 1988), the Motorways Traffic (England and Wales) Regulations 1982 (SI 1982/1163) where a Red X transgression or other regulation 9 offence is engaged, the Civil Liability Act 2018 and Whiplash Injury (Amendment) Regulations 2025 (SI 2025/615) for the injury element, and the Limitation Act 1980 sections 11 and 2 for the time limits. A file built on these references on day one moves cleanly through any third-party insurer process.

Authority: legislation.gov.uk + gov.uk/highway-code

Evidence window for third-party records

National Highways traffic CCTV is retained for around 31 days at the Regional Operations Centre unless the recording is incident-flagged. The HEA (National Highways Agency) incident log is retained against any flagged record. Vehicle event-data - Volvo, Tesla, BMW, Mercedes-Benz, Polestar - must be requested through the manufacturer under UK GDPR before the rolling retention period expires. Bus and HGV telematics retention varies by operator and typically runs 14 to 90 days. Preservation letters sent inside the retention window are the difference between a winnable file and a contested one.

Window: 31 days for National Highways CCTV

Compliance boundary - CMC vs solicitor

CityGrip handles the property-damage chain under FCA CMCOB authorisation - PAS 43 recovery, secure storage, independent engineer instruction, BS 10125 / PAS 125 repair coordination, like-for-like credit hire under Lagden v O'Connor and direct dialogue with the at-fault driver's insurer. Higher-severity motorway personal-injury work is referred to an SRA-regulated solicitor under CMCOB 6 and CMCOB 7 with the referral arrangement disclosed in writing and the customer's separate written consent recorded. The CMCOB 4.3.1R(1A) standalone disclosure - confirming the customer is not obliged to use a claims management company - is rendered on the page before any instruction.

Reference: FCA CMCOB 4, 6, 7

Operational detail - motorway-specific particulars

Motorway files turn on facts no other collision scenario carries: which lane the vehicle was in, whether the section was conventional, Dynamic Hard Shoulder or All Lane Running, whether a Red X was set over the lane at the moment of impact, whether the vehicle had reached an Emergency Area, and what speeds were recorded on the variable mandatory speed limit gantries. CityGrip records the motorway, junction-to-junction location, smart-motorway design, gantry sign state and HATO involvement at intake. Generic templates do not capture the relevant facts on a motorway file.

Method: claim-by-claim, not template

Reviewed entity - who handles what

CityGrip Accident Claims (Citygrip LTD) is the accident-management entity. Independent engineers, PAS 43 recovery operators, BS 10125 / PAS 125 certified bodyshops and SRA-regulated panel solicitors are named on the file at the point of referral. Every onward referral is disclosed in writing with the referral fee position made explicit and the customer's separate written consent recorded. National Highways is the gov.uk-published source for HATO operations and gantry CCTV retention; legislation.gov.uk is the canonical source for every statute cited.

Disclosure: SRA + FCA + ABI panels

Six-step UK motorway post-collision evidence and claim flow

Step one keeps the occupants alive - the secondary-collision risk on a live UK motorway lane is the dominant cause of motorway fatalities. Steps two through four preserve the perishable evidence chain. Steps five and six route the file to the right onward chain - accident-management for the property-damage workstream, OIC portal or SRA-regulated solicitor for the injury workstream depending on severity.

Step 1
Get behind the barrier - Highway Code rule 275
Switch on hazards. If the vehicle is on a hard shoulder, leave by the nearside door and move every occupant behind the safety barrier. If the stretch is All Lane Running and no hard shoulder is available, aim for the next orange Emergency Area before stopping; the inter-Emergency-Area spacing on retrofitted ALR sections is typically under one mile. If the vehicle is stranded in a live running lane and cannot be moved, stay in the vehicle with seatbelts on and hazards activated, and call 999 - exiting into a 70mph running lane is the dominant cause of secondary-collision fatalities on UK motorways. Where occupants are clear of the carriageway, dial 999 or use the orange SOS phone to request a Red X over the closed lane.
Step 2
Comply with section 170 of the Road Traffic Act 1988 and report to the police
Exchange names, addresses, vehicle registration marks and insurer details with every other driver involved. Where injury is present, where details cannot be exchanged, or where any animal listed in section 170(8) is hurt, the collision must be reported to the police as soon as reasonably practicable and in any event within 24 hours. Most UK forces operate online collision-reporting portals; on a serious motorway incident the police will usually be at scene already and will allocate an incident reference at the time. The police accident report (Form 17 / TC1 / regional equivalent) is a routine evidence pull on the third-party file.
Step 3
Capture dashcam, vehicle telematics and event-data records inside 24 hours
Extract and back up the dashcam clip covering the 60 seconds before and 30 seconds after impact within 24 hours - most cameras in continuous-recording mode loop their oldest footage on a 12 to 48 hour cycle. Where the vehicle is a modern Volvo, Tesla, BMW, Mercedes-Benz, Polestar or Audi, the manufacturer retains Intelligent Driving Data event records that include speed, brake application, steering inputs and lane-keeping assist activations - these can be requested through the manufacturer's data-subject access route under UK GDPR. Photograph the position of the vehicle on the carriageway, the lane number, the gantry signal state if visible, and the damage panels before recovery moves the vehicle.
Step 4
Send a preservation letter to National Highways inside the 31-day window
National Highways traffic CCTV - gantry-mounted on smart-motorway sections, pole-mounted elsewhere - is retained for a standard period of around 31 days at the Regional Operations Centre unless the recording is flagged against an incident. A preservation request submitted promptly via the National Highways customer-contact channel, or via the police force handling the scene, secures the gantry footage and the HEA incident log. The HEA log captures every HATO action - Red X activation, lane closure, rolling block, debris clearance - with the times to the second. Where the file is contested, the gantry data and the HEA log together usually resolve the liability dispute.
Step 5
Instruct accident management - PAS 43 recovery, independent engineer, like-for-like replacement
Open the accident-management file at the earliest opportunity. PAS 43 recovery from the live carriageway to a secure storage site preserves the vehicle for the engineer's report. An independent engineer determines the ABI Salvage Code categorisation (Cat A, B, S or N) on neutral ground before the at-fault insurer's chosen engineer sets a reserve. Like-for-like credit hire under Lagden v O'Connor [2003] UKHL 64, with the like-for-like principle confirmed in Bee v Jenson [2007] EWCA Civ 923, keeps the non-fault driver mobile while the property-damage claim moves. Repair work is routed to a BS 10125 / PAS 125 certified bodyshop where the damage warrants it.
Step 6
Route the injury claim - OIC portal or SRA-regulated solicitor based on severity
For soft-tissue whiplash-band injury under £5,000 in general damages, the claim runs through the Official Injury Claim portal at officialinjuryclaim.org.uk under the Civil Liability Act 2018 and the Whiplash Injury (Amendment) Regulations 2025 (SI 2025/615). The high impact energies on UK motorways routinely produce injuries above the small-claims threshold - orthopaedic, spinal, traumatic brain and complex psychological - that take the claim outside the portal. Those files are referred to an SRA-regulated panel solicitor under CMCOB 6 and CMCOB 7, with the referral arrangement disclosed in writing at the point of instruction and the customer's separate written consent recorded.

UK motorway accident claims - FAQs

Which Highway Code rules govern UK motorways?: Motorway driving is covered by rules 253 to 277 of the Highway Code. Rules 253 to 265 cover general motorway driving - who may use the motorway, signs and signals, joining behaviour, lane discipline, overtaking and the prohibition on reversing, U-turns and driving against the traffic flow. Rules 266 to 273 cover joining and leaving the motorway via slip roads. Rules 274 to 277 cover breakdowns, the use of the hard shoulder where one exists, the stranded-vehicle protocol on All Lane Running smart-motorway sections, and the duties of drivers approaching an incident. Breaches of these rules are admissible in any civil or criminal proceedings under section 38(7) of the Road Traffic Act 1988 to establish liability.
What is the difference between motorway accident recovery and a motorway accident claim?: Recovery is the operational job of getting a damaged vehicle off a live motorway carriageway safely under National Highways and police direction - covered separately on the /motorway-accident-recovery page. A motorway accident claim is the legal and insurance process that follows: liability investigation, evidence preservation against gantry CCTV and the National Highways incident log, independent engineer instruction, like-for-like credit hire under Lagden v O'Connor [2003] UKHL 64, personal-injury work through the Official Injury Claim portal or an SRA-regulated solicitor depending on severity, and final recovery of all costs from the at-fault driver's insurer. The two workstreams overlap on day one - the recovery operator's PAS 43 movement record becomes evidence in the claim - but are separately regulated.
Who are National Highways Traffic Officers (HATOs) and what powers do they have?: National Highways Traffic Officers - known as HATOs or Highways Officers, and previously badged Highways Agency Traffic Officers when the agency was the Highways Agency, then Highways England - patrol the English motorway and trunk-road network on behalf of National Highways. They operate under Part 5 of the Traffic Management Act 2004 (sections 6 to 21), which gives them statutory powers to stop and direct traffic, close lanes and carriageways, place temporary signs and signals, manage incidents and request information. Section 6 establishes the role; section 7 sets out the power to direct traffic; section 9 covers powers in relation to vehicles on the strategic road network. HATOs do not have police powers of arrest but operate alongside the police at every serious incident.
What is the rolling block and when do National Highways use it?: A rolling block is a controlled-speed slow-down of all traffic on a stretch of motorway, performed by a National Highways patrol vehicle (or a police vehicle) weaving across the lanes ahead of the incident scene. The traffic behind the patrol vehicle is held at a slow speed, opening a gap in front into which the incident scene can be safely managed - debris cleared, vehicles recovered, casualties attended. The rolling block is the standard live-lane scene-management technique on UK motorways. It is authorised under the HATO direction powers in section 7 of the Traffic Management Act 2004 and runs alongside any police scene management.
What is smart-motorway All Lane Running (ALR) and how does it affect a claim?: All Lane Running is the smart-motorway design in which the former hard shoulder is permanently converted to a fourth running lane. ALR has been in operation since the 2014 M25 J5-7 and M6 J10A-13 schemes and has been retained on existing stretches following the 15 April 2023 Department for Transport decision to cancel all new smart-motorway schemes. On an ALR section there is no hard shoulder available for a routine breakdown - the stranded-vehicle protocol under Highway Code rule 275 therefore points drivers to Emergency Areas (the orange-surfaced refuges placed at intervals along the carriageway) rather than to the verge. A collision file on an ALR section turns on whether a stationary or slow-moving vehicle was struck in a live running lane and whether the Red X gantry signal was set in time.
What was Dynamic Hard Shoulder (DHS) and is it still in use?: Dynamic Hard Shoulder was the earlier smart-motorway design under which the hard shoulder was opened to traffic only during peak periods, when overhead gantry signs activated lane 1. The original M42 Active Traffic Management pilot in 2006 used DHS. Following the Department for Transport's 15 April 2023 announcement, no new DHS schemes are being built and the design is closed for new construction. Existing DHS sections were already being progressively converted to All Lane Running before the announcement. On a DHS section the liability question on a hard-shoulder collision turns on whether lane 1 was open or closed at the moment of impact - gantry signal data is the conclusive evidence and is recoverable from National Highways inside the standard retention window.
What is a Red X and how is it enforced?: A Red X is the overhead gantry signal that closes a motorway lane to traffic. When the lane shows a red X the lane is closed - either because of a stranded vehicle, an incident, debris, lane works or emergency-services activity ahead. Driving in a closed lane is an offence under regulation 9 of the Motorways Traffic (England and Wales) Regulations 1982 (SI 1982/1163), and from June 2019 National Highways has operated automatic ANPR-based detection of Red X transgressions, with the resulting evidence passed to the police. The fixed penalty is £100 with three penalty points; the court-imposed maximum is significantly higher. On a claim file a driver who continued under a Red X faces a near-conclusive contributory-negligence finding and frequently a 100/0 split.
How long does National Highways retain gantry CCTV after a motorway collision?: National Highways operates a network of traffic CCTV cameras on the motorway and trunk-road network - gantry-mounted at smart-motorway sections, pole-mounted elsewhere - feeding the Regional Operations Centres. The standard retention period is typically 31 days unless a recording is flagged for incident review, after which it is held against the relevant National Highways incident log (the HEA / National Highways Agency log). A preservation request submitted promptly via the National Highways customer-contact route, or via the police where the police attended, secures the footage. A request sent after 31 days where the recording was not incident-flagged is usually met with a deletion-already-occurred response. CityGrip drafts the preservation request at intake on every motorway file.
What is the stranded-vehicle protocol under Highway Code rule 275?: Highway Code rule 275 sets the protocol for a vehicle stranded on a UK motorway. Where a hard shoulder is available the driver should pull onto it, switch on hazards, leave the vehicle by the nearside door, walk behind the safety barrier and call 999 or use the orange SOS phone. Where the stretch is All Lane Running and no hard shoulder is available the driver should aim for the next Emergency Area, set hazards on approach and use the SOS phone in the Emergency Area to alert the Regional Operations Centre - which can then set a Red X over the lane the vehicle stopped in. Where the vehicle cannot reach an Emergency Area, occupants should stay in the vehicle with seatbelts on and hazards activated if it is unsafe to exit. The risk of a secondary collision from a following vehicle is the dominant safety concern on every motorway breakdown.
What evidence wins a UK motorway accident claim?: Five categories of evidence dominate motorway files. First, dashcam footage from any vehicle in the immediate area - front-facing, rear-facing and where present cabin-facing - captures the impact, the approach speeds and the lane configuration at the moment of collision. Second, National Highways gantry CCTV from the Regional Operations Centre, recoverable inside the standard 31-day window. Third, the National Highways incident log (HEA log) - a timestamped operational record of every action taken at the scene by HATOs, including any Red X activation and any lane closure. Fourth, telematics and event-data records from modern vehicles - Volvo, Tesla, BMW, Mercedes-Benz and Polestar all retain Intelligent Driving Data event records that include speed, brake application, steering angle and lane-departure-assist activations. Fifth, police accident report (Form 17 / TC1 / equivalent) where the police attended.
Do motorway injury claims go through the Official Injury Claim portal?: Lower-value motorway injury claims do - soft-tissue injuries (whiplash and associated psychological injury) under £5,000 in general damages run through officialinjuryclaim.org.uk under the Civil Liability Act 2018 small-claims regime. The fixed tariff under the Whiplash Injury (Amendment) Regulations 2025 (SI 2025/615) applies for accidents on or after 31 May 2025. The portal is not the right route for higher-severity motorway injuries - the high impact energies on UK motorways routinely produce orthopaedic injury, traumatic brain injury, spinal injury and complex psychological harm that take the claim well above the small-claims limit. Those claims sit outside the portal and proceed through an SRA-regulated solicitor on the standard fast-track or multi-track route.
What happens if I am struck on the hard shoulder of a UK motorway?: Hard-shoulder collisions are a recognised high-severity pattern. A vehicle stopped on the hard shoulder is struck by a vehicle that has either drifted out of lane 1 (fatigue, distraction, mobile-phone use), failed to anticipate the stationary vehicle, or has itself lost control after a debris strike or a tyre failure. The contemporaneous reconstruction turns on dashcam footage from the moving vehicle (where present), National Highways gantry CCTV, the HEA incident log, witness statements from other drivers, and the vehicle damage pattern - a rear-impact collision on the offside of a stopped vehicle establishes a different fault profile from a near-90-degree side impact. CityGrip pulls every available evidence stream inside the National Highways retention window.
How long do I have to bring a UK motorway accident claim?: Three years from the date of the accident or the date of knowledge for any personal injury claim, under section 11 of the Limitation Act 1980. Six years from the date of the accident for vehicle damage and other property loss, under section 2 of the same Act. Where the injured person was a child at the time, the three-year clock starts on the eighteenth birthday. Where the injured person is a protected party under the Mental Capacity Act 2005, the limitation period does not run while the protection continues. Where the at-fault vehicle is uninsured or untraced, the Motor Insurers' Bureau Uninsured Drivers' Agreement 2015 and Untraced Drivers' Agreement 2017 carry their own short notification windows that must also be met. CityGrip records the relevant limitation dates on every file at intake.
