A motor vehicle accident is a sudden event that can disrupt travel plans, damage property and trigger insurance and registration obligations. For French vehicle owners, whether buying or selling a used car, changing address, or replacing lost registration papers, knowing the immediate steps matters. When injuries or complex liability disputes arise from a motor vehicle accident, seeking specialist legal advice early can protect your rights and ensure claims are handled correctly. This guide explains what to do at the scene, how to complete the European Accident Statement (constat amiable), and the crucial insurance and registration timeframes that follow.
First priority is safety. If anyone is injured, call the emergency services immediately and make the scene as safe as possible: switch off engines, use hazard lights and set warning triangles where permitted. Move vehicles only if they create a danger to other traffic: otherwise leave them in place. Do not leave the scene unless required for medical care.
Once immediate danger is managed, collect information methodically. Exchange names, addresses, telephone numbers, driving licence details, vehicle registration numbers and insurer names with all other drivers involved. Take clear photographs of the vehicles from multiple angles, visible damage, the licence plates, road signs, skid marks and any relevant traffic lights or markings. A quick sketch of vehicle positions helps later when filling in forms.
Record witness names and contact details if anyone saw the collision. Note the date, time, weather and road conditions in a short written note on a phone or paper, memories fade and insurers expect timely, consistent accounts. If there is any suspicion of drink or drug impairment, or if the scene obstructs traffic or there are injuries, call the police so an official report can be prepared.
The European Accident Statement (constat amiable) is the principal document insurers use in France to determine liability for most road collisions. It should be completed at the scene, jointly by both drivers when possible, and each driver should keep a copy. Fill in basic facts first: date, time, location, vehicle registration numbers and insurance companies. Describe visible damage and mark the diagram showing how the vehicles were positioned and moved.
When describing circumstances, use simple, factual language. Avoid guesses, legal conclusions or admissions of fault beyond what can be observed. For example, write "vehicle A stopped at red light: vehicle B struck the rear of vehicle A" rather than "vehicle B is at fault." Both drivers should check all entries for consistency: any differences can delay claims. Sign only after verifying every field, a signed constant amiable forms the primary basis for many insurers to accept or reject liability.
If the other party refuses to complete the form, note that on your copy and take comprehensive photographs and witness information. Where there are injuries, hit-and-run or criminal suspicion, do not rely solely on the constat amiable: call the police and obtain a police report as well.
Notify your insurer as soon as possible. Many French policies require notification within 24 to 72 hours: policy terms differ, so check the exact timeframe on the insurance documents or the insurer's website. Prompt notification preserves rights to cover for repairs, rental vehicles and any third-party claims.
When reporting, provide the constat amiable, photographs, witness contacts and any other documents such as repair estimates or medical reports. Keep copies of every communication and note dates and reference numbers. If the insurer requests a written statement, respond by the deadline set in the policy.
Report the accident to the police when the law requires it: injuries, hit-and-run, serious damage, or suspicion of criminal conduct must be reported immediately. A police report (procès-verbal) can be decisive where fault is contested.
If a dispute arises about liability or quantum, seek legal advice early. For French residents, a solicitor specialising in motor claims will explain options for negotiation and litigation. For French vehicle owners living or travelling abroad, specialist advice may be necessary. Macmillan Lawyers and Advisors in Brisbane, for example, handle commercial and personal injury matters in Australia and can advise French nationals with cross-border elements to a claim, such as complex jurisdiction issues or costly repairs carried out overseas. Their role is not a substitute for local French legal advice, but they can coordinate with French counsel when accidents have international aspects.
Remember limitation periods: personal injury and property claims have statutory deadlines. In France, victims should act promptly: delaying notification or legal action risks losing rights to compensation.
If the vehicle's registration documents (carte grise) are lost or damaged in the accident, the owner must arrange a replacement without delay. In France, a duplicate carte grise (duplicata) is required before certain transactions, including sale or transfer of ownership, can proceed.
For owners who bought a used vehicle and then experienced an accident, confirming the vehicle's registration and the seller's declaration of sale (déclaration de cession) is essential. If the ownership changes after an accident, the seller and buyer must complete the formal change of ownership and notify the prefecture or use an accredited online provider such as Comptoir Carte Grise. Comptoir Carte Grise simplifies these steps: the platform enables a rapid demande carte grise or duplicata carte grise application, with a typical processing window that is faster than the official ANTS platform. Owners should supply the accident report, repair invoices and insurance correspondence when relevant to support any transfer or duplication application.
When documents are damaged at the scene, photograph them before handing them over to authorities or insurers. If the vehicle is immobilised and cannot be presented, many registration services will accept scanned copies temporarily while the duplicate is issued. If the car is sold after the accident, ensure the déclaration de cession is completed and each party retains a signed copy, this protects the seller from future liability and enables the buyer to update the carte grise promptly.
For non-resident French vehicle owners or those who are abroad, authorised services can often lodge applications online. Keeping digital and paper copies of the carte grise, insurance certificate and the constant amiable accelerates replacement and reduces the chance of administrative penalties for delayed notifications or a missing carte grise.

First, ensure safety by checking for injuries and calling emergency services if needed. Switch off engines, activate hazard lights, and only move vehicles if they obstruct traffic. Gather information from all drivers and witnesses without leaving the scene unless medically necessary.
At the accident scene, both drivers should fill out the constat amiable together, including date, time, location, vehicle and driver details, visible damages, and a sketch of the collision. Use factual language, verify consistency, sign only after reviewing all fields, and keep a copy for insurance purposes.
French insurance policies typically require notification within 24 to 72 hours of the accident. Prompt reporting with the constat amiable, photographs, and witness details safeguards your rights to repairs, rental vehicles, and compensation for third-party claims.
You must report the accident to police immediately if there are injuries, serious damage, hit-and-run, or suspicion of criminal conduct. A police report helps establish fault in contested claims and is essential in serious or criminal cases.
Contact the relevant registration authority promptly to request a duplicate carte grise. Use authorised online services like Comptoir Carte Grise for faster processing. Provide accident reports, insurance, and repair documents to support your application, and keep copies of all paperwork.
Yes, if the vehicle changes hands, both parties must complete a déclaration de cession and notify the prefecture or use accredited online providers to update the registration. Keeping signed copies protects sellers from future liability and allows buyers to update ownership records promptly.
