Fail to Stop & Failure to Report: UK Driver Guide
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
Being involved in a road traffic incident can be disorientating, and many drivers only later realise they had legal duties at the scene. The law in England and Wales is not limited to dramatic 'hit and run' situations. A low-speed bump in a supermarket car park, clipping a wing mirror, or nudging a bollard on private land accessible to the public can all trigger the same obligations.
If those duties are missed, the consequences can be far more serious than the original incident itself. This guide walks through what the law expects after a collision, the penalties that courts typically impose, the defences that can sometimes apply, and the practical steps worth taking if you believe you may have committed one of these offences. It is written for ordinary drivers trying to make sense of a stressful situation, not for lawyers.
Overview
Failing to stop and failing to report are two separate offences created by section 170 of the Road Traffic Act 1988. They apply whenever a vehicle is involved in an accident on a road or other public place that causes injury to a person, damage to another vehicle, damage to property on or near the road, or injury to certain animals such as dogs, horses, cattle, sheep, pigs, goats and donkeys.
If any of these happen, the driver must stop and, if asked, give their name and address, the owner's name and address, and the vehicle registration mark to anyone with reasonable grounds to ask for them. If details are not exchanged at the scene, for any reason, the driver must then report the incident to the police as soon as reasonably practicable and within 24 hours at the latest.
The two duties are linked but independent: a driver who stops but does not exchange details may still need to report, and a driver who fails to stop is not excused simply because they later report. Both offences can be committed without any intention to evade responsibility, which catches many motorists by surprise.
Key steps
- Stop safely and stay at the scene. If you are involved in any collision or contact, bring your vehicle to a halt as soon as it is safe. Turn on hazard lights, check for injuries, and remain at the scene long enough to fulfil your duties. Driving off, even a short distance to 'find a safer spot' and not returning, can be treated as failing to stop.
- Exchange the required details. Give your full name and address, the name and address of the vehicle's registered keeper if that is someone else, and the vehicle registration number to anyone with reasonable grounds to request them. This typically means the other driver, a property owner, or a pedestrian involved. It is sensible to take their details too and to note the time, location and circumstances.
- Report to the police within 24 hours. If nobody was present to take your details, or nobody asked for them, you must still report the incident at a police station in person, or by calling 101 where that route is accepted locally, as soon as reasonably practicable. Do not wait out the full 24 hours; courts expect prompt action, and the clock starts at the moment of the incident.
- Gather and preserve evidence. Take photographs of vehicle positions, damage, road layout, skid marks and any relevant signage or lighting. Note the names and contact details of witnesses. If a dashcam was running, save the footage immediately so it is not overwritten. This material can be decisive if the facts are later disputed.
- Get guidance before responding to police or insurers. If you receive a Notice of Intended Prosecution, a request for driver information under section 172, or a voluntary interview invitation, how you respond matters. Speaking with an experienced legal adviser before you reply can help you understand what is being asked and the implications of each answer based on what you describe.

Common questions
Q Does the law apply if the accident happened in a private car park?
Possibly, yes. Section 170 covers accidents on a road or 'other public place', and many supermarket, retail park and pub car parks are treated as public places because the public has access to them. A purely private driveway or a locked industrial yard may fall outside the rules, but the boundary is not always obvious, and courts look at the specific facts of access and use.
Q What happens if I genuinely did not know I had been in an accident?
Lack of knowledge can be a defence, but the bar is realistic rather than generous. If a reasonable driver in your position would have felt, seen or heard the impact, a court is unlikely to accept that you were unaware. Minor contact in a busy car park can sometimes pass unnoticed, and evidence such as dashcam footage, vehicle damage and witness accounts all feed into that assessment.
Q Will I automatically lose my licence?
Not automatically, but a driving ban is a real possibility, particularly where injury is involved or the circumstances suggest deliberate avoidance. These offences also carry penalty points within a range set by the courts. If the points added push your total to twelve or more within three years, you face a separate totting-up disqualification. Sentencing is fact-specific.
Q Can I be charged with both failing to stop and failing to report?
Yes. They are distinct offences and prosecutors sometimes charge both arising from the same incident. In practice, where a court sentences for both, it will usually avoid double-counting by imposing penalty points for only one of them, but a conviction is still recorded for each. Fines and any driving ban are considered in the round.
Q How soon do I need to report the incident to the police?
As soon as reasonably practicable, and in any event within 24 hours. 'Reasonably practicable' means without unnecessary delay, so if you could have reported on the day and chose not to, the 24-hour long-stop will not save you. Reporting must generally be in person at a police station, though some forces accept initial reports by phone; check with the relevant force.
Q What if the other driver drove off before I could exchange details?
You should still report the incident to the police within 24 hours, giving as much information as you have, including the other vehicle's registration if you noted it, a description of the driver, and the time and location. Doing so protects you, supports any insurance claim, and helps the police trace the other party.
Q Does reporting to my insurer count as reporting to the police?
No. Insurance notification and police reporting are entirely separate. Telling your insurer is important for any claim, but it does not discharge your duty under the Road Traffic Act. You must report to the police within the statutory timeframe in the required way, in addition to notifying your insurer.
