Time limit for reporting a road accident

This is governed by section 170 of the Road Traffic Act 1988.

The legal position:

If you are involved in a road traffic accident and you fail to stop and exchange the required details at the scene (your name, address, and the registration number of the vehicle, and in cases involving personal injury, your insurance details), you are under a legal duty to report the accident to a police station or to a police constable as soon as reasonably practicable, and in any case within 24 hours of the accident.

The 24-hour deadline is a hard legal limit. Failing to comply with this obligation is a criminal offence under section 170(4) of the Road Traffic Act 1988.

Important details:

1. "As soon as reasonably practicable" is the real standard. The 24 hours is the absolute outer limit, not a target. If you could have reported it sooner but chose not to, you may still face difficulty even if you come in within 24 hours.

2. You must report in person at a police station. A phone call does not satisfy the statutory requirement, although in practice calling 101 or attending a station and finding it closed would be relevant to showing you acted reasonably.

3. If the accident involved personal injury to another person, you must also produce your certificate of insurance at the time of reporting, or produce it at a police station within seven days.

Penalties for failing to stop or failing to report:

The offence carries up to six months' imprisonment, an unlimited fine, and five to ten penalty points on your licence. Disqualification is also possible at the court's discretion. Where the failure to stop or report is combined with serious injury or death, the consequences can be significantly more severe, and the police may also consider charges of dangerous or careless driving depending on the circumstances.

Practical points:

If you have not yet reported and are still within time, go to a police station immediately and report the accident. Take with you your driving licence, insurance certificate, and the vehicle registration details. Make a written note of what happened while it is fresh in your memory, including the time, location, and any details of the other vehicle or people involved.

If you are already past the 24-hour window, reporting late is still significantly better than not reporting at all. It does not guarantee you will avoid prosecution, but voluntary late reporting is treated more favourably than being traced by the police after the event.
