Upfront to driver
A head-on collision is a front-to-front impact between two vehicles travelling toward each other - most commonly on an undivided rural A-road, a single-track country lane or a wrong-way dual-carriageway entry. UK law applies the centre-line rule (Highway Code rules 124 and 160), the single-track passing-place rule (rule 155) and the overtaking framework (rules 162-169). A driver who crosses the centre line into oncoming traffic is virtually always primarily liable. Head-on collisions are over-represented in UK fatal and serious-injury statistics because the closing speed is the sum of the two vehicles' approach speeds, producing impact energies that exceed the design envelope of the modern frontal crumple zone. This page sets out the rule frame, the reconstruction-evidence requirements, the catastrophic-injury solicitor pathway and the Fatal Accidents Act 1976 limitation rules - together with the universal six-step evidence flow.
Head-on collisions sit at the top of the UK injury-severity scale. Two vehicles approaching each other on an undivided road bring a closing speed equal to the sum of their approach speeds - two cars each at 50mph produce a combined-speed impact of 100mph, well beyond the design envelope of the modern frontal crumple zone. The Department for Transport's Reported Road Casualties Great Britain (STATS19) series records rural single-carriageway A-roads as carrying a disproportionate share of UK fatal head-on collisions relative to traffic volume. The fault picture is framed by Highway Code rules 124 and 160 on centre-line discipline, rule 155 on single-track passing places and rules 162 to 169 on overtaking - read with the Road Traffic Act 1988 dangerous and careless driving framework in sections 1, 2, 2A, 2B, 3 and 3A. Head-on files are the most reconstruction-evidence-driven files on the CityGrip ledger and the most likely to be referred immediately to an SRA-regulated catastrophic-injury panel solicitor.
Country-lane head-on collisions sit on single-track roads where the carriageway is wide enough for only one vehicle. The rule that governs them is Highway Code rule 155. The rule requires a driver to pull into a passing place on their left, or wait opposite a passing place on their right, when seeing an oncoming vehicle. Where the nearest passing place is behind, the rule expects the driver to reverse to it where necessary to allow the oncoming vehicle to proceed. Drivers should give way to vehicles coming uphill where possible and be prepared to reverse a considerable distance. The same rule notes that passing places may also be used to allow overtaking vehicles to pass.
Single-track lanes are found extensively across the Highlands, Snowdonia, the Lake District, Cornwall, the Yorkshire Dales and the rural fringes of the Cotswolds and Norfolk. The recurring head-on pattern on these lanes is the passing-place miscommunication: each driver sees the other, each driver expects the other to pull into the passing place visible to one or the other, neither stops, and a low-speed front-to-front contact follows around the next bend. Damage is usually moderate but blocked-lane recovery is operationally difficult - the recovery operator may need to clear several hundred metres of lane to reach the impact site. Higher-speed single-track head-ons (above 40mph) on the longer straights of the A82, A87, A487 or A6 produce damage profiles closer to the centre-line crossing pattern below.
Liability on a single-track-lane head-on turns on the rule 155 analysis. The driver who failed to use an available passing place when the geometry of the road and the relative positions made it the obvious option bears the loss, normally with a partial contributory-negligence reduction where the other driver could also have stopped or reversed. Witness evidence from following or oncoming vehicles, dashcam footage from either driver and the physical evidence of tyre-mark direction at the impact location form the core of the file.
The cleanest head-on liability picture arises from a driver crossing the centre line of an undivided road into oncoming traffic. The duty engaged is under Highway Code rule 160 - drive in the left-hand lane and keep to the left of the carriageway except when overtaking or turning right - read with rule 124 on speed and lane discipline. A driver whose vehicle is found on the wrong side of the road at the moment of impact raises a prima facie case of negligence. The doctrine of res ipsa loquitur, often invoked in the rear-end context, applies with equal force here: the wrong-side position itself speaks of the breach of duty, and the burden shifts to the centre-line-crossing driver to rebut.
The recognised rebuttals are narrow. A medical event - a stroke, a cardiac arrest, a syncopal episode, a hypoglycaemic episode in a diabetic driver with documented good control - is the most commonly pleaded rebuttal and is evidenced by ambulance records, the receiving hospital's clerking, the deceased's GP records where applicable and the coroner's pathology where a fatality results. An unavoidable obstruction in the nearside lane - a tree across the road, a deer or other large animal entering the carriageway, an oncoming vehicle itself crossing the centre line first - is the second category. Mechanical failure (steering, suspension, brake failure) is the third. Where the rebuttal is not made out, the centre-line-crossing driver bears the loss entirely; where partial rebuttal is made out (for example where the oncoming driver was also speeding or briefly distracted) damages are reduced under the Law Reform (Contributory Negligence) Act 1945.
The principle that a driver crossing the centre line is virtually always primarily liable is one of the cleaner doctrines on the civil road-traffic ledger. The reconstruction engineer's task on a centre-line-crossing file is to fix the impact location relative to the centre line (the gouge mark and the debris-field plan-view position are the key physical evidence) and to back-calculate any rebuttable explanation.
The signature high-energy UK head-on collision is the overtaking-into-oncoming event on a rural A-road. Rules 162 to 169 of the Highway Code frame the duty. Rule 162 sets the gateway test - overtake only when it is safe and legal to do so and only where the way is clear. Rule 163 sets out the manoeuvre itself: mirrors, signal, plenty of room, return to the nearside as soon as it is safe. Rule 164 deals with overtaking large vehicles where the view ahead is obscured. Rule 165 is the central head-on rule: do not overtake where it would force you to cross or straddle double white lines (which themselves carry the prohibition under the Traffic Signs Regulations and General Directions), where the road narrows, where you are approaching or at a road junction on either side, where there is a brow of a hill, a school crossing patrol, a pedestrian crossing, a bend, a dip in the road, a narrow road or any other location where you might come into conflict with other road users. Rules 166 to 169 address being overtaken and dual-carriageway overtaking.
The overtaking head-on file follows a predictable shape. The at-fault driver commits to an overtake on a single-carriageway A-road - the A429 across the Cotswolds, the A82 through the Highlands, the A140 across Norfolk, the A487 in Snowdonia, the A6 through the Lake District, the A38 across Devon and Cornwall - without adequate sight-line. An oncoming vehicle appears in the overtaking driver's lane (which is the wrong-side lane); the overtaking driver attempts to abort but the gap to the vehicle being overtaken has closed; the head-on impact follows. The overtaking driver is virtually always primarily liable on rule 165 grounds. Contributory negligence on the oncoming driver is rare and usually limited to a small deduction for any avoidable failure to take evasive action.
Where the overtaking manoeuvre crossed double white lines (the solid line on the overtaking driver's side), the breach is itself an offence under the Traffic Signs Regulations and General Directions 2016 read with section 36 of the Road Traffic Act 1988. The dashcam clip from any vehicle and the tyre-mark evidence on the road surface (the curving yaw mark across the centre line) usually settle the picture cleanly.
The Department for Transport publishes the annual Reported Road Casualties Great Britain series (the STATS19 dataset). The series consistently records rural roads as the road class with the highest fatality rate per billion vehicle miles travelled. Within the rural-road class, single-carriageway A-roads - typically the 60mph national-speed-limit roads connecting market towns through open countryside - are the highest-risk subset. The published figures show single-carriageway A-roads carrying a disproportionate share of fatal collisions relative to the traffic volume they carry, with head-on impacts forming a significant portion of those fatal collisions.
The contributing factors are well-documented and well-understood. There is no central physical separation between opposing traffic streams - no Armco-style barrier, no concrete divider, no soft separator. Differential speeds are high - a tractor, milk-tanker, horsebox or slow tourist vehicle in the carriageway encourages overtaking manoeuvres into the oncoming lane. Sight-lines are limited by bends, brows of hills, dips, hedgerows, drystone walls and roadside vegetation. There is no street lighting in most rural sections, so night-time driving relies entirely on headlamps. Agricultural vehicles, horse riders (Highway Code rules 215-218), cyclists and pedestrians without footways share the carriageway. And rural-road psychology operates against the driver - the open road reduces the perceived risk of error while the actual physical consequence of any error remains catastrophic.
The CityGrip head-on case ledger reflects the geography. The A429 across the Cotswolds, the A82 from Glasgow up to Inverness through the Highlands, the A66 across the Lake District, the A487 along the Snowdonia coast, the A140 across Norfolk, the A30 through Cornwall, the A684 across the Yorkshire Dales - all produce a recurring profile of overtaking-into-oncoming and centre-line-drift fatalities. The fact that the file in any given instance is anchored to a different rural region matters operationally (different police force, different coroner, different ambulance service) but the doctrinal picture is the same wherever the impact happens.
Head-on collisions in the UK present in a small set of recurring patterns. The passing-place miscommunication on a single-track lane - neither driver pulls in to the available passing place, both close at low to moderate speed, front-to-front contact follows around a bend. The overtaking-into-bend on a rural A-road - the at-fault driver commits to an overtake on a single-carriageway A-road without adequate sight-line, an oncoming vehicle appears, the overtaking driver cannot abort safely, high-energy frontal impact follows.
The drift-across-centre-line - caused by drowsiness on a long rural drive, by distraction (phone, satnav, food), by a medical event (cardiac, neurological, hypoglycaemic) or by intoxication. The drift pattern is the cleanest centre-line crossing - the impact is usually at the far edge of the oncoming driver's nearside lane and the yaw-mark evidence shows no late corrective action. The wrong-way-on-dual-carriageway event - rare but catastrophic. A driver enters a dual carriageway via a slip road in the wrong direction, drives several miles against the flow and impacts an oncoming vehicle at the combined speeds of both. The legal analysis is straightforward - the wrong-way driver bears the loss entirely save for unusual mitigation.
The parked-vehicle obstruction head-on - a vehicle parked or stopped on the nearside lane of a narrow rural A-road forces the approaching driver to encroach on the oncoming lane to pass. Where an oncoming vehicle then appears, the encroaching driver is in the wrong-side position and bears primary liability, but the parked vehicle's owner may bear a contributory share where the parking was itself unlawful or obstructive under section 137 of the Highways Act 1980 or under the local authority's traffic regulation order under section 1 of the Road Traffic Regulation Act 1984. The proportion depends on the visibility of the parked vehicle and the available sight-line for the encroaching driver.
The defining characteristic of a head-on collision is the combined-speed impact. Two vehicles approaching each other at 50mph produce a closing speed of 100mph and an impact energy proportional to the square of that figure. Modern frontal crumple zones are designed against a regulatory test regime - Euro NCAP frontal offset deformable barrier test at 64km/h (40mph), Euro NCAP full-width rigid barrier test at 50km/h (31mph), small overlap and centre-pole tests in the recent protocols - but the regulatory envelope assumes one vehicle impacting a fixed structure, not two vehicles impacting each other at the sum of their approach speeds. Head-on closing speeds of 100mph and above routinely exceed the design envelope.
The damage pattern reflects the energy. Severe frontal-crumple-zone deployment, with the bonnet folding upwards, the wings buckling, the engine block displacing rearwards into the bulkhead, the footwell intruding into the lower-limb space and (at higher energies) the A-pillars distorting and the windscreen frame collapsing. Front airbag deployment is universal at impact speeds above the deployment threshold (typically 25km/h closing speed front-on for a single airbag-equipped vehicle, but head-on impacts always trigger). Seatbelt pretensioners deploy with the airbag. Knee airbags, curtain airbags and (in side-impact-secondary cases) side airbags may also deploy. The pretensioner deployment leaves a characteristic friction burn pattern across the chest and shoulder on the seatbelt line.
The occupant injury pattern is severe frontal-impact polytrauma. Multiple long-bone fractures (femur, tibia, ankle), pelvic fracture from seatbelt loading on the lap belt, chest-wall injury with rib fractures from the shoulder-belt loading and the airbag, pulmonary contusion, possible aortic injury (a high-mortality pattern), abdominal injury, head injury (concussion through to traumatic brain injury and diffuse axonal injury at higher energies), facial injury despite airbag deployment, lower-limb injury from footwell intrusion. Fatal outcomes are over-represented. The Sentencing Council guidelines for causing death by careless and dangerous driving - and the related offences under sections 1, 2, 2B and 3A of the Road Traffic Act 1988 - apply at the criminal end of the proceedings, with coroner-inquest considerations under the Coroners and Justice Act 2009 running alongside.
HEAD-ON
Section 3 of the walkthrough.
Head-on collision files are uniquely reconstruction-evidence-driven. The tyre-mark direction analysis is the starting point. A yaw mark - a curved tyre track left when a vehicle is sliding sideways with the wheels still rotating - captures the trajectory of each vehicle in the moments before impact. The yaw radius, combined with the road-surface coefficient of friction measured at scene with a drag-sled, feeds into the critical-speed-yaw calculation that gives the minimum speed at which the vehicle was travelling at the start of the yaw. Skid marks (straight, dark, four-wheel under heavy braking) and scrub marks (where a wheel was being dragged sideways under braking and steering input) give additional information on driver input. Gouge marks left by deformed metalwork contacting the road surface fix the impact location to within centimetres.
The road-surface debris field is photographed in plan view before recovery vehicles disturb it. Broken glass, plastic trim, dropped fluids, displaced load - the spread direction and density gradient record the direction of momentum carry after impact, which constrains the closing-speed back-calculation. Witness positioning matters: a witness in a following vehicle has seen the approach but may not have seen the impact itself; a witness in a stationary roadside vehicle (a parked car, a pub or shop frontage) has the cleanest line of sight; a witness in an oncoming vehicle in the same direction as either party has a partial view. Dashcam capture of approach speed and lane discipline from either vehicle, where the camera survived the impact, is the single most valuable single piece of evidence. Telematics data from any insurer black-box policy gives independent speed, position and braking input records around the impact moment.
Skid reconstruction techniques include brake-bias analysis (the distribution of braking force front-to-rear, used to back-calculate pre-impact braking from skid intensity), drag-sled coefficient of friction testing (a calibrated sled dragged across the road surface to measure the friction available), and critical-speed-yaw calculation (the formula relating yaw radius, friction coefficient and minimum vehicle speed at the start of the yaw). The standard reference texts are the SAE J224 vocabulary, the Northwestern Center for Public Safety reconstruction methodology and the Institute of Traffic Accident Investigators (ITAI) training programme.
Head-on collisions sit uncomfortably between two evidence patterns from the insurer's perspective. Where one driver was unambiguously on the wrong side of the road and the other was unambiguously on the correct side, the liability picture is clean and the wrong-side driver's insurer admits quickly. Where both vehicles had partial centre-line encroachment, where both drivers committed to manoeuvres at similar moments, where the road geometry made the boundary ambiguous, or where a passing-place miscommunication is in play, liability is heavily contested. Insurers' own panel engineers often reach divergent conclusions on closing speeds and on the impact location relative to the centre line. Reconstruction-engineer evidence on neutral ground becomes critical.
The major UK motor insurers - Aviva, AXA, Allianz, Direct Line, Admiral, Hastings, LV=, RSA, Esure, Churchill, More Than, Saga, NFU Mutual (which carries a heavy rural-driver book), Lloyds Banking Group brands and the broker schemes - handle head-on claims through specialist large-loss teams rather than the volume motor desks. Reserves are set high from the moment injury severity is established. Where the at-fault driver was uninsured or untraced the claim moves to the Motor Insurers' Bureau under the Uninsured Drivers' Agreement 2017 or the Untraced Drivers' Agreement 2017; the procedural rules are stricter and notification deadlines apply.
For any head-on collision with serious injury, polytrauma, prolonged hospital admission or fatal outcome, the personal-injury or fatal-accident claim is referred immediately to an SRA-regulated panel solicitor with documented catastrophic-injury experience. The Civil Liability Act 2018 small-claims regime and the Official Injury Claim portal are designed for low-value whiplash claims and are not the right route for a head-on polytrauma file. CityGrip's onward referral runs under FCA CMCOB 6 and CMCOB 7 with the referral fee position disclosed in writing, the customer's (or bereaved family's) separate written consent obtained before transfer, and the standalone CMCOB 4.3.1R(1A) disclosure provided in writing in advance. CityGrip does not undertake personal-injury work itself - it is an accident management company, not a firm of solicitors, and the boundary is observed strictly.
Where the injury exceeds the £5,000 small-claims threshold the file leaves the OIC portal and runs as a full personal injury claim after a car accident with general and special damages assessed separately from the whiplash compensation tariff. Panel solicitors handle these on a no win, no fee conditional fee agreement so there is no upfront cost. If the at-fault driver carried no valid insurance, the file routes through the MIB - see our pages on a MIB uninsured driver claim or, where the at-fault driver fled the scene, a MIB untraced driver claim.
Where a head-on collision results in a fatality, the deceased's dependants have a statutory claim under the Fatal Accidents Act 1976 as amended. The class of qualifying dependants - the spouse or civil partner, the children (including step-children and adopted children), parents, certain other defined relatives - was extended by the Civil Partnership Act 2004 and the Marriage (Same Sex Couples) Act 2013. The recoverable heads of loss are loss of dependency (lost financial support from the deceased's income), the statutory bereavement award (currently £15,120 for deaths on or after 1 May 2020 under the Damages for Bereavement (Variation of Sum) (England and Wales) Order 2020), funeral expenses and the costs of any pre-death suffering. The Law Reform (Miscellaneous Provisions) Act 1934 separately preserves the deceased's own cause of action for the benefit of their estate.
The limitation period sits in section 12 of the Limitation Act 1980 - three years from the date of death or from the date of knowledge of the relevant dependant. Each dependant has their own limitation clock; in practice a single bereaved family may have several different limitation dates running in parallel, and the file must track each separately. A child dependant's clock does not start until the child's eighteenth birthday. A protected party under the Mental Capacity Act 2005 has no clock running while capacity is absent. Our wider guide to the accident claim time limit sets out the section 11 three-year period for non-fatal injury and the section 2 six-year period for vehicle damage.
A coroner's inquest will normally be opened where the death arises from a road traffic collision. The inquest is governed by the Coroners and Justice Act 2009 and the Coroners (Inquests) Rules 2013. The coroner's evidence - the pathology report, the police collision investigation report, the toxicology, the witness statements - is separately useful to the civil claim and to any criminal proceedings under sections 1, 2B or 3A of the Road Traffic Act 1988. CityGrip's fatal head-on referral to the panel catastrophic-injury solicitor coordinates the civil, inquest and criminal tracks so that the bereaved family does not have to manage three separate evidence streams.

Ranking factors
The six factors that distinguish a strong UK head-on collision claim from a weak one. The clean centre-line-crossing case tilts the starting point heavily in the non-fault driver's favour; the disputed-encroachment case turns on reconstruction-engineer evidence; the catastrophic-injury and fatal cases require immediate SRA-regulated panel solicitor referral. CityGrip handles each on a claim-by-claim basis.
Head-on files turn on physical evidence captured before recovery vehicles move debris. Yaw-mark photography, debris-field plan-view shots, vehicle resting positions, registration plates and witness contact details locked down inside the first three days. Where any occupant is hospitalised, a CityGrip handler attends to the scene-evidence task on the family's behalf so the reconstruction is not lost while the priority is intensive care.

Head-on collisions are uniquely reconstruction-evidence-driven. The combined-speed impact destroys both vehicles, scatters the debris field, leaves yaw marks visible only for hours under rain and traffic, and produces a damage pattern that requires accredited engineer interpretation. An ITAI-accredited reconstruction engineer instructed inside 14 days, with road-surface friction coefficient measured at scene and critical-speed-yaw calculation completed, is the single biggest determinant of clean apportionment between contested insurers.

Head-ons sit in the catastrophic-injury and fatal-accident tier far more often than other collision patterns. Polytrauma, traumatic brain injury, spinal injury and fatal outcome dictate immediate referral to a documented SRA-regulated catastrophic-injury solicitor - not to the OIC portal small-claims route. CityGrip's panel referral runs under CMCOB 6 and CMCOB 7 with the customer's (or bereaved family's) separate written consent obtained before transfer. CMCOB 4.3.1R(1A) standalone disclosure makes the customer's choice visible in writing before any onward instruction.

The same six steps apply to every UK head-on collision, from a low-speed passing-place miscommunication on a Highlands single-track lane to a high-energy overtaking-into-oncoming fatality on a Cotswolds A-road. Step one secures the scene with priority on the serious-injury response; step six opens the accident management file with the reconstruction engineer instructed and the SRA-regulated catastrophic-injury solicitor referral made where the injury severity warrants it. Speak to a CityGrip handler at any point in the flow.
Step 1
Make the scene safe and prioritise serious-injury response
Head-on collisions sit at the top of the UK injury-severity scale. Do not try to extract a casualty from a wrecked vehicle unless fire, fuel leak or water makes the vehicle position unsurvivable. Switch on hazard warning lights, set the warning triangle at least 45 metres back where road type permits (not on a motorway), and call 999 for police, ambulance and fire and rescue. Where the impact has blocked a single-carriageway A-road or a country lane, oncoming traffic is the immediate threat - flag down approaching vehicles around any blind brow or bend before they crest. On a dual carriageway or motorway live lane do not exit the vehicle if it remains drivable to the verge or hard shoulder; National Highways protocol is to remain in the vehicle with seatbelts on where exit is unsafe. Note registration plates and vehicle positions even if you cannot photograph them in the first moments.
Step 2
Preserve the tyre-mark, debris and vehicle-position evidence before recovery
Head-on collisions are reconstructed from the physical evidence on the road surface. Before recovery vehicles arrive and move debris, photograph every yaw mark, skid mark and gouge mark in plan view; photograph the road-surface debris field (glass, plastic trim, fluid pools) showing direction of spread; photograph each vehicle's final resting position from at least four angles; photograph the road geometry showing the centre line, any double white lines under the Road Traffic Regulation Act 1984 and any sight-line obstruction. Record the time, the road name, the nearest mile marker and the weather conditions in a voice note on a phone. The fire and rescue service may dictate that you stay clear of an immobilised vehicle with deformed structure or a deployed pretensioner - comply with that direction; photograph from the cordon line.
Step 3
Exchange details under section 170 RTA 1988 and report to police
Every driver involved must give name, address, vehicle registration mark and the name and address of the insurer to every other driver and to any person reasonably requiring them, under section 170 of the Road Traffic Act 1988. Where any person is injured (which is the norm in a head-on), where details cannot be exchanged at the scene because of injury, where details are refused, or where an animal listed in section 170(8) is killed or injured, the collision must be reported to the police as soon as reasonably practicable and in any event within 24 hours. In any serious-injury head-on the police will normally already be in attendance; the police collision reference number is the spine of the file. Where the at-fault driver has fled the scene the case becomes a hit-and-run under section 170(4) and the file runs against the MIB Untraced Drivers' Agreement 2017.
Step 4
Back up dashcam and telematics data before it is lost
Dashcam footage from either vehicle is the single most important piece of evidence where it survives. Most consumer dashcams overwrite on a 24- to 48-hour loop; the SD card must be removed and the clip backed up to cloud storage and a second physical device within 24 hours. The clip should run at least 60 seconds before impact and 60 seconds after. Any insurer black-box telematics record (Marmalade, Admiral Little Black Box, ingenie, Carrot) captures speed, GPS position, lateral acceleration and braking input around the impact moment - a written preservation request should be sent to the telematics provider inside 14 days. Any CCTV from a roadside pub, agricultural building or shop visible to the impact location is preserved on a 28-day retention cycle at most - preservation letters under data protection law and the pre-action protocol must be sent inside that window.
Step 5
Instruct an independent reconstruction engineer
Where injury is serious, where liability is contested or where a fatality is involved, an independent reconstruction engineer accredited by the Institute of Traffic Accident Investigators (ITAI) should be instructed inside the first 14 days. The engineer's brief covers tyre-mark direction analysis (yaw pattern), road-surface debris-field analysis, vehicle damage geometry, restraint-deployment data extraction from the event data recorder where present, road-surface friction coefficient testing with a drag-sled and impact speed back-calculation using the critical-speed-yaw method or equivalent. The engineer's report stands as neutral evidence before either insurer's panel engineer reaches a position. For a fatal head-on the engineer's report also informs the coroner's inquest and any subsequent prosecution under sections 1, 2, 2B or 3A of the Road Traffic Act 1988.
Step 6
Open the accident management file and consider SRA-regulated referral
Open a file with an accident management company at the earliest opportunity. Recovery from the scene to a secure PAS 43 storage site, an independent engineer's report under the ABI Salvage Code (Cat A, B, S or N - head-on collisions frequently total the vehicles), like-for-like credit hire instruction where the non-fault claimant survived the impact and is mobile, and repair coordination at a BS 10125-certified bodyshop all start from the same call. For a head-on with serious injury, polytrauma, prolonged hospital admission or fatal outcome, the personal-injury or fatal-accident claim is referred immediately to an SRA-regulated solicitor with documented catastrophic-injury experience, with the referral arrangement disclosed in writing under CMCOB 6 and CMCOB 7 and the customer's (or bereaved family's) separate written consent obtained before any onward transfer. The standalone CMCOB 4.3.1R(1A) disclosure - you are not obliged to use a claims management company - is given in writing before any instruction.
Head-on collisions are the most reconstruction-evidence-driven files on the UK road-traffic ledger and the most likely to require an SRA-regulated catastrophic-injury panel solicitor. Scene-evidence preservation, ITAI-accredited reconstruction engineer instruction, secure PAS 43 recovery and storage, like-for-like credit hire where the non-fault driver survived ambulatory and Fatal Accidents Act 1976 dependants' referral with separate written consent.
