You were driving your UK-registered car through France when another vehicle clipped you at a roundabout, or you woke to find your parked car smashed and no note on the windscreen. Since Brexit, British drivers face the same French road-accident rules as everyone else, but with unfamiliar paperwork, a foreign language and an insurer that may be based in another country. This guide explains, step by step, what a British driver should do in the first hours after a road accident in France, how the French system decides who pays for injuries and vehicle damage, and how to challenge an insurer that refuses to pay or offers too little. It covers both visitors on a short trip and British residents driving a UK-registered or French-registered car, the paper constat amiable and the e-constat app, the criminal consequences of leaving the scene, and the strict deadlines that protect victims under French insurance law.
I. What should a British driver do in the first hours after an accident on a French road?
The minutes after a collision matter more in France than many British drivers expect. France uses a shared accident report called the constat amiable, meaning an amicable accident statement, a standard two-copy form that both drivers fill in and sign together. What you write on that form shapes the insurers’ decision on liability, so it pays to understand it before you ever need it. Where someone is hurt, or the other driver refuses to cooperate or drives away, the police or gendarmerie take over, and different rules apply.
A. How do you fill in the constat amiable so that it protects your claim?
The constat amiable, the European accident statement form carried in most French-insured cars, is the single most important document after a minor collision in France. The official service-public.fr page on the subject explains how to complete the constat amiable after an accident, and an electronic version called the e-constat auto now exists alongside the paper form. If you drive a UK-registered car in France, download the e-constat app or keep a blank paper constat in the glove box before you travel, because the other driver will almost certainly produce one and expect you to fill in your half on the spot.
Fill in the form calmly and factually. Each driver completes one column, describing their own vehicle, their insurer and policy number, and the circumstances in a shared central section with tick boxes and a sketch. Draw the sketch carefully, showing the position of both vehicles, the direction of travel, road markings and signs, because adjusters rely on it heavily. Tick only the boxes that truly describe what your vehicle was doing. A wrong tick, for example stating that you were changing lanes when you were in fact established in your lane at a roundabout, can reverse the finding on liability. Write the time, the exact place, and the names and addresses of any witnesses, meaning independent witnesses rather than your own passengers, whose evidence an insurer must take seriously. Take photographs of both vehicles, the number plates, the road layout and any debris before the cars are moved, and keep them with your copy.
Sign the form only when you agree with everything on it. Once both drivers have signed, the front of the constat cannot be altered, so check the other driver’s column before signing. If you disagree about what happened, say so in the observations box, meaning the free-text comments section, rather than refusing to sign. A constat signed by only one driver still has value, but a jointly signed constat recording agreed facts is far harder for an insurer to disregard. Each driver keeps one copy and sends it to their own insurer, and in practice you should notify your insurer within five working days of the accident, keeping proof of postage or the acknowledgment of receipt for an online declaration. British residents who imported a UK car should also read the companion guide on customs clearance, the 846A certificate and ANTS registration for a British driver’s UK car in France, because an insurer may query cover where the vehicle’s registration position is unclear.
Be precise about injuries. If anyone feels pain, dizziness or shock, call the emergency services on 15, the SAMU, or 112, the European emergency number, and mention it on the constat. Under the French victim-compensation system, bodily injury claims follow special protective rules on medical assessment and insurer offers, described in Part II below, and early medical records become the baseline for everything that follows. Go to the urgences, the hospital accident and emergency department, or your médecin traitant, your registered GP, the same day even if you feel almost well, and keep every certificate, prescription and receipt. Whiplash and soft-tissue injuries often appear the next morning, and a gap in the medical record gives the insurer room to argue that your symptoms came from something else.
Language difficulties do not excuse errors. If your French is limited, complete the observations box in English as well as attempting the tick boxes, photograph the whole signed form, and write your own dated account of the accident while it is fresh. Ask the other driver for their permis de conduire, the driving licence, carte grise, the vehicle registration certificate now called certificat d’immatriculation, and attestation d’assurance, the insurance certificate, and photograph them. Note the other vehicle’s country of registration. If the other driver is uninsured, refuses to show documents, or behaves aggressively, do not argue at the roadside. Record what you can, call the police, and let the guarantee fund procedure described below take over.
B. When must you call the police, and what happens if the other driver flees the scene?
Call the police or the gendarmerie immediately whenever someone is injured, when a driver appears to be under the influence of drink or drugs, when the drivers cannot agree on the facts, or when a driver refuses to stop or drives off. In towns the Police nationale or Police municipale attends, while outside built-up areas the Gendarmerie nationale has jurisdiction. The officers draw up a procès-verbal, the official police report, which carries significant weight with insurers and courts. Ask for the report number and the brigade’s contact details before you leave, and request a copy later for your file. Where the accident blocks the road or involves a lorry carrying dangerous goods, also call 17 for the police or 18 for the fire brigade, the sapeurs-pompiers.
Leaving the scene of an accident you have caused or been involved in is a criminal offence in France called the délit de fuite, meaning the hit-and-run offence. The rule is strict and every British driver should understand it, because even a moment of panic can turn a simple insurance matter into a criminal case. Article 434-10 of the Code pénal, the French Criminal Code, provides that “Le fait, pour tout conducteur d’un véhicule ou engin terrestre, fluvial ou maritime, sachant qu’il vient de causer ou d’occasionner un accident, de ne pas s’arrêter et de tenter ainsi d’échapper à la responsabilité pénale ou civile qu’il peut avoir encourue, est puni de trois ans d’emprisonnement et de 75 000 € d’amende.” The Code de la route, the French Highway Code, repeats these provisions in its article L231-1, and adds that a convicted driver also faces suspension of the driving licence for up to five years, a suspension that cannot be limited to driving outside work. Note the breadth of the definition: it covers any driver who knows they have just caused or been involved in an accident and fails to stop in order to escape possible criminal or civil liability, even where the damage looks slight.
Two recent rulings of the Cour de cassation, the French supreme court for civil and criminal matters, show how the courts interpret this offence, and both help British drivers understand its boundaries. In a judgment of 1 October 2025 on appeal number 24-86.411, the criminal chamber recalled the text and explained that “Est ainsi sanctionnée une entrave à l’exercice de la justice dans la détermination des circonstances d’un accident, en vue d’établir d’éventuelles responsabilités.” The protected interest, in other words, is the justice system’s ability to establish what happened. The same ruling then drew an important limit: “L’incrimination d’un tel comportement n’est pas compatible avec une déclaration de culpabilité qui caractérise l’usage intentionnel d’un véhicule, par la personne poursuivie, en vue de commettre un dommage matériel ou corporel, le dommage ainsi causé ne présentant pas le caractère d’un événement fortuit et ne pouvant donc être qualifié d’accident.” A deliberate ramming with a car is prosecuted as violence, not as a hit-and-run on top, because the damage was intentional rather than an accident in the legal sense. In a second judgment of 24 March 2026 on appeal number 25-82.140, the criminal chamber held that “le délit de fuite ne peut être retenu qu’à l’encontre du conducteur d’un véhicule ou engin”, meaning only the driver, and not a passenger who runs away with the driver, can commit the hit-and-run offence, since the statute punishes “tout conducteur d’un véhicule ou engin terrestre, fluvial ou maritime, sachant qu’il vient de causer ou d’occasionner un accident, de ne pas s’arrêter et de tenter ainsi d’échapper à la responsabilité pénale ou civile qu’il peut avoir encourue”. A British passenger who panics and leaves the scene therefore faces different charges, such as failure to assist a person in danger, rather than the délit de fuite itself.
The practical lesson is simple. Always stop, exchange details, help the injured, and wait for the emergency services where they have been called. If the other driver flees, memorise the number plate, the make, model and colour of the vehicle, and the direction it took, photograph the scene, and give everything to the police. Your own claim does not die with the fleeing driver: as Part II explains, the guarantee fund compensates victims of unknown or uninsured drivers. And remember that ordinary traffic offences remain your personal responsibility as the person at the wheel. Article L121-1 of the Code de la route states that “Le conducteur d’un véhicule est responsable pénalement des infractions commises par lui dans la conduite dudit véhicule.” A related guide on French speeding fines, ANTAI notices and UK licences after Brexit explains what happens when the offence is excess speed rather than a collision.
II. How does French law decide who pays for a road accident, and how do you challenge a refusal or a low offer?
Once the dust has settled, the question becomes money: who pays for the dented wing, the hire car, the broken wrist and the months off work. France answers it through a combination of compulsory motor insurance, a victim-friendly statute from 1985 known as the Loi Badinter, the general law of civil liability, and strict procedural deadlines that force insurers to make reasoned offers quickly. British victims benefit from exactly the same rules as French victims for accidents on French soil, and they hold two powerful procedural weapons: a direct claim against the other driver’s insurer, and a statutory timetable for compensation offers with penalties for delay.
A. Who pays for your injuries and your vehicle damage under French traffic-accident law?
Start with insurance. France makes motor insurance compulsory, and the obligation covers British drivers on French roads in the same way. Article L211-1 of the Code des assurances, the French Insurance Code, provides that “Toute personne physique ou toute personne morale autre que l’Etat, dont la responsabilité civile peut être engagée en raison de dommages subis par des tiers résultant d’atteintes aux personnes ou aux biens dans la réalisation desquels un véhicule est impliqué, doit, pour faire circuler celui-ci, être couverte par une assurance garantissant cette responsabilité, dans les conditions fixées par décret en Conseil d’Etat.” Anyone whose civil liability could be engaged for damage to third parties in which a motor vehicle is involved must therefore be covered by liability insurance before driving. Driving without valid insurance in France is itself a criminal offence punishable by heavy fines and possible confiscation of the vehicle, so a British motorist should verify before every trip that their UK policy covers driving in France and carry the insurance certificate in the car. The gov.uk guidance for UK licence holders living in the EU sets out the United Kingdom side of the position on licences and driving abroad, and it should be checked alongside the French rules explained here.
For bodily injury, France applies the Loi n° 85-677 du 5 juillet 1985, the statute for improving the position of road-traffic victims and speeding up compensation, universally called the Loi Badinter after the minister who introduced it. Its philosophy is that road-traffic victims should be compensated quickly and generously through the insurers, with the driver’s fault playing only a limited role. Non-driving victims such as pedestrians, cyclists and passengers are compensated almost automatically, while a driver’s own fault can reduce or exclude their compensation only in narrowly defined circumstances, and never where the victim is under sixteen, over seventy, or seriously disabled. In practice the victim or their lawyer notifies the liable driver’s insurer, supplies the medical evidence, and the insurer must then follow the statutory offer procedure examined in the next section. Property damage, by contrast, still turns largely on fault, proven mainly through the constat amiable, photographs, the police report and witness statements, against the background of the general principle in article 1240 of the Code civil, the French Civil Code, that “Tout fait quelconque de l’homme, qui cause à autrui un dommage, oblige celui par la faute duquel il est arrivé à le réparer.”
Two safety nets matter especially for British drivers. First, what if the other driver is uninsured or untraced. France maintains a Fonds de garantie des assurances obligatoires de dommages, the Guarantee Fund for compulsory insurance, known as the FGAO, which steps in where the liable driver is unknown or uninsured. Article L421-1 of the Code des assurances provides that “Le fonds de garantie des assurances obligatoires de dommages indemnise, dans les conditions prévues aux 1 et 2 du présent I, les victimes ou les ayants droit des victimes des dommages nés d’un accident survenu en France dans lequel est impliqué un véhicule au sens de l’article L. 211-1”, covering personal injury where the person responsible is unknown or uninsured, and property damage under conditions set by decree. A British visitor hit by an uninsured driver on the autoroute, or sideswiped by a car that speeds off with unreadable plates, therefore still has a solvent payer for personal injuries. The claim goes through the Fund with the police report and medical evidence, and a lawyer’s letter framing the request against the statutory conditions speeds matters considerably.
Second, what if the accident involves vehicles from two countries. A collision in France between a UK-registered car and a French car is handled under French compensation rules for the French proceedings, with each victim claiming against the liable driver’s insurer and the national bureaux system settling accounts between insurers behind the scenes. Keep both insurers informed from day one, send each the constat, and never accept an oral statement from either insurer that the foreign element removes your rights. It does not. The French victim-protection rules apply because the accident happened in France, and the foreign registration of one vehicle changes the paperwork, not the substance of your rights.
B. How do you claim, what deadlines bind the insurer, and how do you challenge a refusal or a low offer?
French law gives victims a direct action against the liable driver’s insurer, called the action directe, meaning the right for the injured third party to sue the insurer directly without first suing the driver. Article L124-3 of the Code des assurances states that “Le tiers lésé dispose d’un droit d’action directe à l’encontre de l’assureur garantissant la responsabilité civile de la personne responsable.” The Cour de cassation gave this provision full effect in a judgment of its second civil chamber on 16 December 2021, appeal number 20-16.340, where a car owner whose vehicle had been hit sued the other driver’s insurer directly after meeting silence. The Court held that “Il résulte de ce texte, selon lequel le tiers lésé dispose d’un droit d’action directe à l’encontre de l’assureur garantissant la responsabilité civile de la personne responsable, que la recevabilité de l’action directe contre cet assureur n’est pas subordonnée à la déclaration préalable du sinistre par la victime auprès de son propre assureur.” A British victim therefore does not need to claim first on their own UK policy or to have declared the accident to their own insurer before suing the French insurer of the driver who caused the crash. The direct action stands on its own, which matters enormously where the victim’s own UK insurer is slow, uncooperative, or purports to apply English claims-handling habits to a French accident.
The insurer, in return, is bound by one of the strictest offer timetables in French consumer-protection law. Article L211-9 of the Code des assurances requires that “Quelle que soit la nature du dommage, dans le cas où la responsabilité n’est pas contestée et où le dommage a été entièrement quantifié, l’assureur qui garantit la responsabilité civile du fait d’un véhicule terrestre à moteur est tenu de présenter à la victime une offre d’indemnité motivée dans le délai de trois mois à compter de la demande d’indemnisation qui lui est présentée.” Where injuries are involved, the backstop is even clearer: “Une offre d’indemnité doit être faite à la victime qui a subi une atteinte à sa personne dans le délai maximum de huit mois à compter de l’accident.” The offer must be reasoned, meaning it must explain the basis of liability and the calculation of each head of loss, and it may be provisional, called a provision or offre provisionnelle, where the victim’s condition has not yet stabilised, with a final offer due within five months of being informed of stabilisation. Late or incomplete offers carry statutory interest penalties, and article L211-22 extends these duties to the Guarantee Fund in its dealings with victims. In plain terms, the insurer cannot simply go quiet. If three months pass after your quantified claim without a reasoned response, or eight months pass after the accident without an injury offer, the insurer is already in breach, and that breach becomes leverage.
Time limits also protect victims, but they must be respected. For bodily injury, article 2226 of the Code civil provides that “L’action en responsabilité née à raison d’un événement ayant entraîné un dommage corporel, engagée par la victime directe ou indirecte des préjudices qui en résultent, se prescrit par dix ans à compter de la date de la consolidation du dommage initial ou aggravé.” Consolidation, the medical stabilisation of the injury, means the point at which doctors consider the condition stable enough to assess permanent effects, and the ten-year clock runs from that date, not from the accident itself, with aggravation capable of restarting discussion. Property-only claims follow shorter limitation periods, so vehicle-damage claims should be pursued without delay and never parked behind the injury file. Keep every medical certificate describing the initial injuries and each stage of consolidation, because the insurer will scrutinise the chain from the first urgences report to the final expertise médicale, the independent medical assessment that underpins the valuation of pain, suffering, disability and lost earnings.
When the insurer refuses liability, disputes the facts, or makes an offer that undervalues your loss, challenge it methodically. First, reply in writing within the file, point by point, attaching the constat, the photographs, the police report number, the witness details and the medical certificates, and remind the insurer of the three-month and eight-month deadlines with their penalty interest. Second, commission a contre-expertise, an independent counter medical assessment, where the insurer’s doctor minimises your injuries, and have a French-speaking representative attend any joint medical examination with you. Third, use the statutory mediation and complaints ladder: the insurer’s service réclamations, the complaints department, then the Médiation de l’assurance, the insurance ombudsman, while keeping the limitation clock in view. Fourth, where the deadlock persists, issue proceedings before the tribunal judiciaire, the ordinary civil court, of the place of the accident or of the defendant’s domicile, suing the driver’s insurer directly under article L124-3 and claiming the penalty interest for late offers alongside the substantive damages. Paris practice is organised: accidents in the capital are handled by the Tribunal judiciaire de Paris with its road-injury chambers and a deep pool of approved medical experts, so a British resident in Île-de-France should expect the expertise to be ordered locally and should prepare French translations of UK medical records, payslips and employment evidence for loss-of-earnings claims. Throughout, never sign a transaction, the formal settlement agreement, or cash a final cheque described as full settlement, until independent advice confirms that every head of loss, including future care, assistance by a third person, adapted housing and pension loss, has been valued. A signed settlement in France is very difficult to reopen, even where later symptoms emerge, outside the narrow aggravation procedure.
Conclusion
A road accident in France need not become a legal accident for a British driver. Complete the constat amiable with care and never sign what you dispute, call the police whenever there are injuries or a driver who will not cooperate, and always stop, because leaving the scene turns an insurance file into a criminal prosecution for délit de fuite punishable by three years’ imprisonment and a 75,000 euro fine. Then use the protection French law gives every victim on French soil: compulsory insurance behind every vehicle, the victim-friendly logic of the Loi Badinter, the Guarantee Fund where the other driver is uninsured or unknown, a direct action against the liable driver’s insurer that needs no prior claim on your own policy, reasoned offers within three months of your quantified claim and eight months of the accident, and ten years from medical consolidation to bring the bodily-injury claim. Where the insurer refuses or underpays, answer on paper, build the medical evidence, invoke the deadlines and their penalties, and take the direct action to court rather than accepting a low offer. Handled this way, a crash on a French road remains what it should be: a bad day, a file number, and full compensation, not a lasting injustice.
