How to prove your accident (no witness, no contact, hit-and-run)

Practical guide · Updated 2026-06-01

For road accidents, French law strongly protects victims. But you still need to establish that a vehicle was involved — especially where there was no contact.

Build a body of evidence

Photos and videos of the scene, skid marks, debris.
Nearby CCTV footage (shops, streets) — ask quickly, it gets erased.
Dashcam and your vehicle data.
Written witness statements, with contact details.
The accident report, and above all a police complaint in case of a hit-and-run.

The no-contact accident

A vehicle can be involved even without impact, if it played a role in the accident. But this involvement is not presumed: it is up to the victim to prove it, by any means.

Hit-and-run or uninsured driver

File a complaint quickly. If the driver remains unknown or is uninsured, the French guarantee fund (FGAO) may compensate your bodily injury, subject to conditions.

Secure your file early

The value of evidence is assessed case by case. Early support prevents decisive elements from disappearing.

Frequently asked questions

Without a witness, am I doomed to a 50/50 split?

Not necessarily. Photos, CCTV, dashcam, physical traces and a complaint can re-establish your version. The absence of a witness should be noted on the report.

Does the guarantee fund cover material damage?

The fund mainly steps in for bodily injury when the driver is unknown or uninsured. For material damage the conditions are more restrictive.
