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.<\/p>\n
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.<\/p>\n
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<\/a> 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.<\/p>\n 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.<\/p>\n 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<\/a>, because an insurer may query cover where the vehicle’s registration position is unclear.<\/p>\n 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 m\u00e9decin 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.<\/p>\n 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.<\/p>\n 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 proc\u00e8s-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.<\/p>\n Leaving the scene of an accident you have caused or been involved in is a criminal offence in France called the d\u00e9lit 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 p\u00e9nal<\/a>, the French Criminal Code, provides that “Le fait, pour tout conducteur d’un v\u00e9hicule ou engin terrestre, fluvial ou maritime, sachant qu’il vient de causer ou d’occasionner un accident, de ne pas s’arr\u00eater et de tenter ainsi d’\u00e9chapper \u00e0 la responsabilit\u00e9 p\u00e9nale ou civile qu’il peut avoir encourue, est puni de trois ans d’emprisonnement et de 75 000 \u20ac d’amende.” The Code de la route, the French Highway Code, repeats these provisions in its article L231-1<\/a>, 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.<\/p>\n 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<\/a>, the criminal chamber recalled the text and explained that “Est ainsi sanctionn\u00e9e une entrave \u00e0 l’exercice de la justice dans la d\u00e9termination des circonstances d’un accident, en vue d’\u00e9tablir d’\u00e9ventuelles responsabilit\u00e9s.” 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 d\u00e9claration de culpabilit\u00e9 qui caract\u00e9rise l’usage intentionnel d’un v\u00e9hicule, par la personne poursuivie, en vue de commettre un dommage mat\u00e9riel ou corporel, le dommage ainsi caus\u00e9 ne pr\u00e9sentant pas le caract\u00e8re d’un \u00e9v\u00e9nement fortuit et ne pouvant donc \u00eatre qualifi\u00e9 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<\/a>, the criminal chamber held that “le d\u00e9lit de fuite ne peut \u00eatre retenu qu’\u00e0 l’encontre du conducteur d’un v\u00e9hicule 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 v\u00e9hicule ou engin terrestre, fluvial ou maritime, sachant qu’il vient de causer ou d’occasionner un accident, de ne pas s’arr\u00eater et de tenter ainsi d’\u00e9chapper \u00e0 la responsabilit\u00e9 p\u00e9nale 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 d\u00e9lit de fuite itself.<\/p>\n 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<\/a> states that “Le conducteur d’un v\u00e9hicule est responsable p\u00e9nalement des infractions commises par lui dans la conduite dudit v\u00e9hicule.” A related guide on French speeding fines, ANTAI notices and UK licences after Brexit<\/a> explains what happens when the offence is excess speed rather than a collision.<\/p>\n 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.<\/p>\n 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<\/a>, the French Insurance Code, provides that “Toute personne physique ou toute personne morale autre que l’Etat, dont la responsabilit\u00e9 civile peut \u00eatre engag\u00e9e en raison de dommages subis par des tiers r\u00e9sultant d’atteintes aux personnes ou aux biens dans la r\u00e9alisation desquels un v\u00e9hicule est impliqu\u00e9, doit, pour faire circuler celui-ci, \u00eatre couverte par une assurance garantissant cette responsabilit\u00e9, dans les conditions fix\u00e9es par d\u00e9cret 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<\/a> 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.<\/p>\n For bodily injury, France applies the Loi n\u00b0 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<\/a>, the French Civil Code, that “Tout fait quelconque de l’homme, qui cause \u00e0 autrui un dommage, oblige celui par la faute duquel il est arriv\u00e9 \u00e0 le r\u00e9parer.”<\/p>\n 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<\/a> provides that “Le fonds de garantie des assurances obligatoires de dommages indemnise, dans les conditions pr\u00e9vues aux 1 et 2 du pr\u00e9sent I, les victimes ou les ayants droit des victimes des dommages n\u00e9s d’un accident survenu en France dans lequel est impliqu\u00e9 un v\u00e9hicule 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.<\/p>\n 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.<\/p>\n 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<\/a> states that “Le tiers l\u00e9s\u00e9 dispose d’un droit d’action directe \u00e0 l’encontre de l’assureur garantissant la responsabilit\u00e9 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<\/a>, where a car owner whose vehicle had been hit sued the other driver’s insurer directly after meeting silence. The Court held that “Il r\u00e9sulte de ce texte, selon lequel le tiers l\u00e9s\u00e9 dispose d’un droit d’action directe \u00e0 l’encontre de l’assureur garantissant la responsabilit\u00e9 civile de la personne responsable, que la recevabilit\u00e9 de l’action directe contre cet assureur n’est pas subordonn\u00e9e \u00e0 la d\u00e9claration pr\u00e9alable du sinistre par la victime aupr\u00e8s 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.<\/p>\n 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<\/a> requires that “Quelle que soit la nature du dommage, dans le cas o\u00f9 la responsabilit\u00e9 n’est pas contest\u00e9e et o\u00f9 le dommage a \u00e9t\u00e9 enti\u00e8rement quantifi\u00e9, l’assureur qui garantit la responsabilit\u00e9 civile du fait d’un v\u00e9hicule terrestre \u00e0 moteur est tenu de pr\u00e9senter \u00e0 la victime une offre d’indemnit\u00e9 motiv\u00e9e dans le d\u00e9lai de trois mois \u00e0 compter de la demande d’indemnisation qui lui est pr\u00e9sent\u00e9e.” Where injuries are involved, the backstop is even clearer: “Une offre d’indemnit\u00e9 doit \u00eatre faite \u00e0 la victime qui a subi une atteinte \u00e0 sa personne dans le d\u00e9lai maximum de huit mois \u00e0 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<\/a> 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.<\/p>\n Time limits also protect victims, but they must be respected. For bodily injury, article 2226 of the Code civil<\/a> provides that “L’action en responsabilit\u00e9 n\u00e9e \u00e0 raison d’un \u00e9v\u00e9nement ayant entra\u00een\u00e9 un dommage corporel<\/a>, engag\u00e9e par la victime directe ou indirecte des pr\u00e9judices qui en r\u00e9sultent, se prescrit par dix ans \u00e0 compter de la date de la consolidation du dommage initial ou aggrav\u00e9.” 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 m\u00e9dicale, the independent medical assessment that underpins the valuation of pain, suffering, disability and lost earnings.<\/p>\nB.
