Someone jumped a red light and hit me: liability and what to do (UK)
A driver who goes through a red light and collides with your vehicle has breached one of the clearest duties in road law: the obligation under section 36 of the Road Traffic Act 1988 to comply with a traffic signal. For the non-fault driver, that statutory breach means liability is usually resolved quickly - provided the right evidence is secured in the hours and days immediately after the collision.
This guide explains why a red-light collision almost always lands liability on the driver who jumped the light, the narrow exceptions that a third-party insurer might try to argue, and the practical steps to protect your position, claim recovery, repairs and a replacement vehicle at no upfront cost.
Why liability almost always falls on the driver who ran the red
Section 36 of the Road Traffic Act 1988, read together with the Traffic Signs Regulations and General Directions 2016, creates an absolute duty for every driver to comply with the red aspect of a traffic signal. Running a red light is a criminal offence punishable by a fixed-penalty notice and three penalty points. In civil terms, a driver who proceeds through a red signal and strikes a vehicle lawfully crossing on green has committed a clear act of negligence: they failed to keep a proper look-out, failed to observe the signal and drove into a space occupied by another road user who had priority.
English courts have consistently held that the burden of proof in such cases falls on the driver who was on the wrong aspect. If you crossed on green and the other driver went through a red, the insurer for the other driver faces an almost unanswerable liability case provided the evidence establishes the signal state. That evidence - traffic-light camera data, junction CCTV, dashcam footage and witness accounts - is what the first 24 hours are about.
It is worth noting that the non-fault driver does not have to prove a criminal standard of proof. The civil standard is the balance of probabilities. Dashcam footage showing your signal turning green seconds before the impact, combined with the impact geometry and road positions, is typically sufficient. You do not need the police to issue a ticket to the other driver before the insurer will accept liability.
DETAIL

Section 3 of the walkthrough.
Evidence that proves the other driver ran the red
Traffic-light cameras. Many UK junctions are equipped with fixed traffic-enforcement cameras that photograph vehicles entering the controlled zone after the signal has turned red. If the police attend, they can request the imagery. If they do not attend, the relevant local authority or Highways England can be asked to preserve footage before automatic deletion, which typically occurs after 28 to 31 days.
Junction CCTV. Local authorities operate their own CCTV networks for traffic management. In London, Transport for London's camera estate covers most signalised junctions on the TfL Road Network. Outside London, the relevant local authority highways department holds the footage. A formal preservation request should be made within 48 to 72 hours; many authorities will delete footage after 14 days unless a hold is placed.
Your own dashcam. A front-facing dashcam that captured your signal phase turning green, the moment of impact and the other vehicle's trajectory is often decisive. Preserve the original memory card and do not overwrite the footage. Download a copy to cloud storage immediately. If your dashcam timestamps video, the footage is even more useful.
The other driver's dashcam. The third-party insurer is required by the Civil Procedure Rules Pre-Action Protocol for Personal Injury Claims to disclose any dashcam footage held by their insured that is relevant to liability. If the dashcam shows the signal state at the other vehicle's approach, the insurer cannot withhold it in proceedings.
Witnesses. Pedestrians waiting to cross, passengers in other vehicles and drivers stopped at the same junction frequently witness red-light collisions. Take contact details at the scene. A pedestrian who confirms they were waiting for the pedestrian phase - which only illuminates when vehicles have a red - is compelling corroborative evidence.
Damage geometry. The engineer's inspection of both vehicles will show the impact geometry: where each vehicle was struck and in what direction relative to the other. A vehicle proceeding lawfully on a green phase at a junction will typically take the impact on the front quarter, side or door. This is consistent with a vehicle crossing from the other driver's direction. Impact geometry alone is not conclusive, but combined with other evidence it supports the account.
Narrow exceptions where the insurer may try to argue liability
A well-resourced insurer will look for any argument to reduce or extinguish liability. In a red-light case, the most common argument is that your signal was not green when you entered the junction. This is why evidence of your own signal phase is important, not just evidence that the other driver had a red.
A second argument is contributory negligence: even though the other driver ran the red, you drove into the junction without adequate observation. The duty to take reasonable care does not disappear merely because you had priority. However, the standard of care expected of a driver on a green signal does not require anticipation of a lawbreaking driver on a red. A driver on green is entitled to proceed. Contributory negligence arguments in straightforward red-light cases tend to fail unless there were visible warning signs - flashing amber, an approaching vehicle clearly not slowing - that the reasonable driver should have heeded.
If the amber phase was active when you entered the junction rather than green, the position is more nuanced. The Highway Code advises treating amber as stop unless you have already crossed the stop line or are so close to it that stopping would be dangerous. If you crossed on a late amber, the insurer may argue a degree of shared responsibility. Document honestly what you observed; insurers have access to signal-timing logs from the local authority that show the exact phase at the time of the collision.
What to do at the scene of a red-light collision
Stop and fulfil your section 170 duties. Even though you are not at fault, the duty to exchange details and, if required, report to the police applies to all drivers involved. Take the other driver's name, address, vehicle registration, insurer and policy number. Do not accept any claim by the other driver that the collision was your fault; exchange details politely without discussion of cause.
Call the police if anyone is injured, the road is blocked, or the other driver is uncooperative, provides false details or leaves the scene. If the police attend, give them the same account you would give the insurer - factual, not speculative. Note the CAD or CRIS reference before they leave.
Photograph everything. The resting positions of both vehicles, the damage, the junction layout, the signal heads, any skid marks, and the road surface. If your dashcam preserved the footage, tell the officer. Photograph the traffic-signal housing so the insurer and their engineers can identify which signal controls traffic from your direction.
Do not move your vehicle until you have photographs. Moving cars before photographing the rest positions destroys evidence of the impact geometry and the approach paths.
Open an accident management file within the hour. Recovery, an independent engineer's inspection and a replacement vehicle can all be arranged at no upfront cost to you when the other driver is at fault. The accident management company will put the third-party insurer on notice and handle the insurer's initial liability inquiries.
06DETAILKey takeaway
Claiming recovery, repairs and a replacement vehicle
Where liability is clear and the third-party insurer accepts it, you are entitled to recover from them: the cost of recovery and secure storage of your vehicle; an independent engineer's inspection to assess damage and market value; the cost of repair at an approved repairer or a total-loss settlement at fair market value; and a reasonable credit-hire replacement vehicle for the period you were without your car.
None of these costs fall on you as the non-fault driver, provided you act promptly, preserve evidence, and refer the claim through an accident management company that operates on a credit basis (recovering costs from the at-fault insurer, not from you). You should not be required to pay excess, surrender a no-claims bonus or accept a vehicle from the at-fault insurer's hire fleet as a condition of the claim.
Where liability is disputed - perhaps because the other driver claims the lights were not red for them - the claim proceeds on a credit basis while liability is resolved. This means you are not left without a vehicle or stranded with a damaged car while a dispute runs. The accident management company handles the insurer correspondence and, where needed, coordinates with solicitors for the litigation phase.
What if the other driver disputes the lights?
Red-light disputes are more common than they should be. Some drivers genuinely remember the signal differently; others are motivated by the cost and policy implications of a fault claim. Either way, a liability dispute does not mean you are left without recourse.
The Pre-Action Protocol for Personal Injury Claims (which also governs property-damage claims where injury may be involved) requires the third-party insurer to investigate and respond to a letter of claim within three months. If they deny liability, they must set out the basis of the denial. You then have the evidence gathered in the first 72 hours - dashcam, CCTV preserved in time, witness statements, damage geometry and signal-timing logs - to mount a positive case.
Signal-timing logs are particularly important. The local authority highways department holds logs from traffic signal controllers that record the exact phase sequence with timestamps. A disclosure request or, in proceedings, a Part 18 request for specific disclosure, can produce logs that show definitively what phase was active at the time of the collision. Combined with CCTV or dashcam footage, these logs make a red-light dispute very difficult for the at-fault insurer to sustain.
If the dispute proceeds to county court, the small claims track applies to property-damage claims up to £10,000, reducing the risk of adverse costs. Personal injury claims are handled under the whiplash-tariff system via the Official Injury Claim portal or through the Fast Track, depending on value. In either case, a driver who objectively ran a red light has an extremely weak position in a contested hearing.

Specific limits, retention windows and process steps may change; the position at the date of any individual collision will govern the handling of that claim.
Frequently asked questions
- Do I need the police to issue a ticket before my claim can proceed?
- No. The civil claim proceeds on the balance of probabilities, not the criminal standard. A police ticket to the other driver is helpful supporting evidence but is not a prerequisite for a non-fault claim. CCTV, dashcam footage and signal-timing logs are typically sufficient.
- What if there are no cameras at the junction?
- Camera coverage is one of several evidence streams, not the only one. Witnesses, damage geometry, dashcam footage from other vehicles in the area, and signal-timing logs from the local authority all contribute. An uncameraed junction does not mean no evidence.
- Can I be found partly at fault even though I had a green light?
- In theory, yes - but contributory negligence arguments in red-light cases very rarely succeed unless you had a visible warning (flashing amber, a vehicle clearly not braking) that a reasonable driver should have acted on. Proceeding on a green signal is lawful and the standard of care does not require anticipating lawbreaking.
- How long do I have to claim?
- For property damage the limitation period under the Limitation Act 1980 is six years. For personal injury it is three years from the date of the accident. However, CCTV is deleted within 14 to 31 days. Act within 24 to 48 hours to secure evidence, even if the formal claim takes longer to open.
- What if the other driver left the scene?
- Note as much as you can: registration, make, model, colour, direction of travel. Report to the police within 24 hours under section 170(6) Road Traffic Act 1988. If the driver cannot be traced, the Motor Insurers' Bureau Untraced Drivers' Agreement 2017 provides a route to compensation for injury and property damage.
