What to do after a road accident in France

Practical guide · Updated 2026-06-01

The hours following an accident are decisive. What you do — or fail to do — will later weigh on the recognition of your losses. Here are the essential reflexes.

1. Secure the scene and alert

Get to safety, switch on your hazard lights. If anyone is injured, call the emergency services (15, 18 or 112): their intervention leaves a useful record.

2. Complete the report (constat) or a police report

Fill in an accident report with the other driver. If there are injuries, the electronic report is not suitable: use the paper report and involve the police, who will draw up an official report.

3. See a doctor without delay

Even if the pain seems mild, obtain an initial medical certificate, ideally within 24 to 72 hours. It links your injuries to the accident. Mention every symptom, including sleep problems, anxiety and headaches.

4. Gather evidence

Photograph the scene, the vehicles and your injuries. Note the witnesses (name, phone, email). Keep everything: report, invoices, sick notes, medical records.

5. Report to your insurer — and get advice

Declare the claim within the deadline, but do not sign any offer or release before having your rights checked. An early offer is almost always lower than the compensation you may be entitled to.

Frequently asked questions

Should I call the police for a minor accident?

Not necessarily if no one is injured: an amicable report is enough. But as soon as there is an injury, a serious disagreement or a hit-and-run, involving the police is strongly advised.

I only felt pain the next day — is it too late?

No. See a doctor quickly and ask them to note that your symptoms are consistent with the accident. The closer the consultation is to the accident, the harder the link is to contest.
