You shipped your right-hand-drive car from Dover, or you drove it down through the Tunnel, and now it sits on GB plates outside your house in the Dordogne, the Charente or the suburbs of Paris. Since Brexit that car is no longer an EU vehicle on a routine hop across the Channel. It is a third-country vehicle, you are a third-country national living in France, and three French clocks started ticking the day you arrived: the one-month deadline to apply for a French certificat d’immatriculation (the registration certificate everyone still calls the carte grise), the obligation to hold French motor insurance from the moment you become resident, and the need for a French contrôle technique (the periodic roadworthiness test, the rough equivalent of the MOT) once the car falls due. Miss any of them and the same drive to the shops can end with a fine, an immobilisation order, or your car in the fourrière, the official vehicle pound, with the storage bill running daily at your expense. This guide walks you through the whole chain in order: notifying the DVLA and clearing French customs, registering the car with the ANTS (the Agence nationale des titres sécurisés, the national agency for secure documents that issues registration certificates), sorting roadworthiness and insurance, and challenging the ticket or the impound decision if the police say you got it wrong.
I. Making your British car French: registration, roadworthiness and insurance after Brexit
France does not have one single vehicle formality. It has four separate ones, handled by four different bodies, and each one can sink the others if you neglect it. Customs wants its clearance paper. The ANTS wants the registration file. An approved contrôle centre wants to inspect the car. And a French insurer wants to cover your liability before the wheels turn. Take them in that order and keep every receipt, because the paper trail is what saves you at the roadside and before the court.
A. Telling the DVLA, clearing customs and registering with the ANTS within one month
Start on the British side before the ferry sails. The gov.uk guidance on taking a vehicle out of the country treats any absence of twelve months or more as a permanent export that must be notified to the DVLA. In practice you complete the permanent-export section of the V5C log book, keep the remainder of the document for the French registration file, and post the completed section to the DVLA in Swansea, adding a letter with your new address where a vehicle-tax refund may be due. Keep a copy of everything you send, because the French file will ask what the car was and where it came from, and the V5C remainder is your proof. Full details are on the gov.uk permanent export page.
At the French border, Brexit changed the customs story completely. A car arriving from the United Kingdom is now an import from outside the European Union, not an intra-Community transfer. The ANTS procedure for registering a second-hand vehicle bought abroad therefore asks for a customs clearance certificate (the form 846A) or, failing that, a written exemption statement from the customs authorities, as the official service-public.fr English page explains (see the service-public.fr registration page and the ANTS foreign-vehicle page). In practice, contact the customs office (bureau de douane) of your future French home before you ship the car: households genuinely transferring their residence to France can often bring their long-owned car in free of duty and VAT under the personal-effects relief, but the relief has conditions on length of prior ownership and use, it must be claimed with the right form, and if you miss it the bill can reach 20 percent VAT plus 10 percent duty on the car’s assessed value. Never assume the ferry booking counts as a customs declaration. Get the 846A certificate or the written exemption first, because without one of them the ANTS will simply refuse the file.
Then comes the French registration itself, and the deadline is short. The same service-public.fr page states the deadline without ambiguity: owners have one month to apply for the new registration certificate, online or through an authorised motor-trade professional. The application goes to the Minister of the Interior through the ANTS website or the Simplimmat application, or through an authorised motor-trade professional (garagiste habilité). The statute behind that page is article R. 322-1 of the Code de la route, which opens: “Tout propriétaire d’un véhicule à moteur autre qu’un cyclomobile léger, d’une remorque dont le poids total autorisé en charge est supérieur à 500 kilogrammes ou d’une semi-remorque et qui souhaite le mettre en circulation pour la première fois doit faire une demande de certificat d’immatriculation en justifiant de son identité.” Your British file must add the import-specific pieces on top of the standard ones: proof of identity, proof of French address, the V5C and bill of sale, the customs 846A or exemption, and the Certificate of Conformity (COC) issued by the manufacturer proving the car meets an approved European type, or failing that a single-vehicle approval (réception à titre isolé) through the DREAL, the regional environment and planning authority. Right-hand-drive cars with a full European COC normally pass this stage, but headlamp dip direction, rear fog light position and speedometer markings in miles per hour are the three classic traps, so budget for the beam-deflector or headlamp work before the inspection rather than after a refusal.
Two companion duties complete the registration picture. First, the ANTS may ask you to prove insurance and a driving licence for the vehicle category at any point: article R. 322-1 of the Code de la route further requires the owner to be able to prove, on demand: “De la souscription, pour le véhicule considéré, d’une assurance conforme aux dispositions de l’article L. 211-1 du code des assurances” and, where the owner is a private individual, a driving licence covering the relevant vehicle category, a point on which the provision cross-refers to article L. 322-1-1. That cross-reference matters for British licence holders: article L. 322-1-1 of the Code de la route states that “Lorsque qu’une personne physique propriétaire d’un véhicule effectue une demande de certificat d’immatriculation, ce certificat est établi à son nom si cette personne est titulaire d’un permis de conduire correspondant à la catégorie du véhicule considéré.” If your UK licence was never exchanged and you cannot evidence the matching entitlement, the certificate goes in someone else’s name, which is exactly the administrative tangle you want to avoid, so sort the licence exchange in parallel with the car file. Second, once the car carries French plates, every later move of house restarts a smaller clock: article R. 322-7 of the Code de la route provides that “Tout propriétaire d’un véhicule soumis à immatriculation doit, dans le mois qui suit le changement de domicile, de siège social ou d’établissement d’affectation ou de mise à disposition du véhicule, adresser par voie électronique une déclaration au ministre de l’intérieur l’informant de ce changement.” Fines go to the address on the file, so an out-of-date address means you learn about the ticket from the majorée, the increased penalty, months later.
If instead of importing you buy a car already in France, the seller’s paperwork duty is just as strict and the courts enforce it. When a used vehicle already registered changes hands, article R. 322-4 of the Code de la route requires that “En cas de changement de propriétaire d’un véhicule soumis à immatriculation et déjà immatriculé, l’ancien propriétaire doit effectuer, dans les quinze jours suivant la cession, une déclaration au ministre de l’intérieur l’informant de cette cession et indiquant l’identité et le domicile déclarés par le nouveau propriétaire.” The seller must bar through the old certificate, hand it over, and declare the sale within fifteen days, while you as buyer apply for the new certificate within the month. Judges treat the registration document as part of what the seller owes you, not as an optional extra. In a judgment of 25 September 2025 the Tribunal judiciaire de Vannes recalled that under the Civil Code the seller’s delivery duty is wide: the court cited the rule that the “obligation de délivrer la chose comprend ses accessoires et tout ce qui a été destiné à son usage perpétuel”, and the buyer’s claim shows the remedy sought in these cases: “Condamner le garage AUTOCCASION 29 à remettre à Monsieur [E] le certificat d’immatriculation du véhicule et ce sous astreinte de 100 € par jour de retard passé un délai de 8 jours à compter de la notification de la décision” (Tribunal judiciaire de Vannes, 25 September 2025, no. 24/00721, full judgment on courdecassation.fr). For a British buyer this is a practical shield: never drive away with only the keys and a handshake. Insist on the barred certificate, the signed cession declaration (déclaration de cession) and the contrôle technique report where one is due, and check the fifteen-day seller declaration has been made, because an undeclared sale leaves the old owner’s name on the national file and their fines landing on your doormat.
B. Passing the contrôle technique and taking out French insurance before you drive
Registration gets the car a French identity. Roadworthiness and insurance make it lawful to move. British newcomers sometimes assume a valid MOT and an unexpired UK policy cover the transition period. They do not, or at least not in the way that matters once you live here. An MOT is a British certificate for a British-registered vehicle; once you are resident in France and the car must carry French plates, only a French contrôle technique counts, and a UK insurer’s European cover note is written for holidays and temporary stays, not for a policyholder who has moved their permanent home abroad. Drive for months on the old combination and you accumulate two separate offences at once, each with its own penalty scale.
The contrôle technique is run by the State or by State-approved controllers in approved centres: article L. 323-1 of the Code de la route states that “Lorsqu’en application du présent code, des véhicules sont astreints à un contrôle technique, celui-ci est effectué par les services de l’Etat ou par des contrôleurs agréés par l’Etat dans des installations agréées.” For ordinary cars the rhythm is fixed by article R. 323-22 of the Code de la route: first test “D’un contrôle technique dans les six mois précédant l’expiration d’un délai de quatre ans à compter de la date de leur première mise en circulation”, then repeat inspections every two years after that, under the same article R. 323-22. The same article requires a test before any transfer of a car older than four years unless one was done in the previous six months, which is why a private purchase without a recent report should ring alarm bells. Book the test as soon as the car lands if its fourth birthday is near or past, because the ANTS file for an older imported vehicle will expect a valid report, and because driving to the test centre with an overdue test is itself ticketable outside the direct route and appointment justification. Right-hand-drive specifics belong in the preparation: headlamp alignment converted for driving on the right, a rear fog lamp on the correct side, tyres with the right load index, and a speedometer showing kilometres per hour or a clear dual display. A British-market car with miles-only dials can fail, and the retest fee plus the lost week hurt far more than a pre-shipment check.
Insurance is the heavier obligation of the two, because it protects third parties and the criminal law treats it accordingly. Article L. 211-1 of the Code des assurances lays down the universal duty: “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.” Note the breadth: everyone whose liability could be engaged, for any motorised land vehicle put into circulation. Driving uninsured, even through simple carelessness, is not a parking-ticket matter but a criminal offence (délit): article L. 324-2 of the Code de la route punishes “Le fait, y compris par négligence, de mettre ou de maintenir en circulation un véhicule terrestre à moteur ainsi que ses remorques ou semi-remorques sans être couvert par une assurance garantissant sa responsabilité civile conformément aux dispositions de l’article L. 211-1 du code des assurances”, and the penalty is “puni de 3 750 euros d’amende”, with further additional penalties available to the criminal court and consecutive sentencing where other driving offences were committed at the same time. Take out a French policy the week you arrive, not the week the UK policy expires. Ask the French insurer explicitly whether your UK no-claims history can be recognised, declare the car’s British origin, its right-hand drive and any modification, and get the green insurance sticker (now the electronic record plus the memo on the vehicle insurance database) sorted before the first school run. Keep proof of cover in the car at all times, because article R. 233-1 of the Code de la route requires that “tout conducteur ou, le cas échéant, tout accompagnateur d’un apprenti conducteur, est tenu de présenter à toute réquisition des agents de l’autorité compétente” the driving entitlement, the registration certificate and the insurance evidence. At a rural checkpoint, the gendarme’s first three questions are licence, carte grise, assurance, in that order, and hesitation on any of them sets the tone for the rest of the stop.
The declaration you sign for the insurer deserves the same care as the ANTS file, because an inaccuracy can destroy the cover retroactively. French insurance law allows the insurer to seek annulment of the whole contract where the policyholder intentionally misled it about the risk. Article L. 113-8 of the Code des assurances provides: “Indépendamment des causes ordinaires de nullité, et sous réserve des dispositions de l’article L. 132-26 , le contrat d’assurance est nul en cas de réticence ou de fausse déclaration intentionnelle de la part de l’assuré, quand cette réticence ou cette fausse déclaration change l’objet du risque ou en diminue l’opinion pour l’assureur, alors même que le risque omis ou dénaturé par l’assuré a été sans influence sur le sinistre.” Paid premiums stay with the insurer, and the victim is still compensated by the guarantee fund mechanism before the insurer turns back against the annulled policyholder, so the driver who hid something pays twice: no indemnity and a recourse bill. A recent appeal decision shows how unforgiving this is for undisclosed vehicle changes. The insurer Axa discovered after a motorcycle accident that the bike carried an undisclosed additional injection module affecting engine performance and the characteristics shown on the registration certificate; the court of appeal held that the hidden change necessarily altered the insurer’s assessment of the risk, annulled the policy and ordered costs against the policyholder: “Prononce la nullité du contrat Moto souscrit par M. [I] auprès de la société Axa France Iard n° 10005850804 du 16 mai 2018” (Cour d’appel de Versailles, 15 January 2026, RG 23/07867, full judgment on courdecassation.fr). Two protective rules from the same judgment are worth memorising. First, “La charge de la preuve de cette fausse déclaration pèse sur l’assureur qui s’en prévaut.” Second, “Il incombe aussi à l’assureur de démontrer en quoi la fausse déclaration intentionnelle a changé l’objet du risque ou en a diminué son opinion”, a requirement the court traced to the Cour de cassation (Civ. 2ème, 12 December 2013, pourvoi no. 12-28.829). For a British owner this cuts both ways: declare everything in writing at subscription, the import, the right-hand drive, the remap, the tow bar, the declared value, and keep the questionnaire answers, because silence about a performance change can void the policy after the crash; but if an insurer later cries foul over a trivial omission, make it prove both the intentional falsehood and the changed risk assessment, because the burden is entirely on the insurer.
II. Stopped with GB plates: fines, impound and how to challenge them
British plates in a French village are not invisible. Automatic number-plate cameras, gendarmerie patrols and even the neighbourly town-hall clerk can all notice that the same GB car has been parked in the same street for a year. Once the police stop you, the officer works down a short checklist: is the car registered where its keeper lives, is it insured in France, is it roadworthy, and are the papers in order. Each wrong answer is a separate procedure with its own paper, its own deadline and its own appeal route, and confusing them is how winnable cases are lost. What follows separates the three tracks and gives you the challenge method for each.
A. What the police can write up: unregistered car, no French insurance and the pound
The lightest of the three tracks, on paper, is circulation without registration. Article R. 322-1 of the Code de la route, the same provision that orders owners to apply, closes with the sanction: “Le fait, pour tout propriétaire, de mettre en circulation un véhicule sans avoir obtenu un certificat d’immatriculation est puni de l’amende prévue pour les contraventions de la quatrième classe.” A fourth-class contravention ticket (amende forfaitaire) is the standard outcome at a first clean stop: a fixed fine notice handed over or sent to the keeper, with a reduced amount for prompt payment and an increased amount (majorée) if ignored. Do not read “light” as “harmless”. The ticket goes with penalty points logic for other offences, it flags the car for the next stop, and if the underlying situation is not regularised the second stop can escalate to immobilisation, where the officer physically prevents the car from moving on with a wheel clamp, a confiscated registration document or an order to drive directly to a garage or test centre.
The second track is the absence of French insurance, and it jumps a full category into criminal law. As seen above, article L. 324-2 punishes putting or keeping an uninsured motor vehicle into circulation with 3,750 euros of fine, and the offence needs no intent: negligence is expressly enough. At the roadside this means the officer can have the vehicle immobilised on the spot and, where the cover gap is confirmed, the public prosecutor can order the car into the pound. The pound procedure has its own definition worth knowing word for word: article R. 325-12 of the Code de la route states that “La mise en fourrière est le transfert d’un véhicule en un lieu désigné par l’autorité administrative ou judiciaire en vue d’y être retenu jusqu’à décision de celle-ci, aux frais du propriétaire de ce véhicule.” Those last five words are the sting: daily storage fees, removal fees and expert fees accumulate against the owner while the car sits behind the fence, and release requires showing valid insurance and registration plus payment of the costs. An uninsured British car that entered France lawfully on a green card in January and is still running on expired foreign cover in October is the textbook pound case, because the file shows a resident keeper, a foreign plate and no French policy, which reads at a glance as a deliberate evasion.
The third track is behaviour at the stop itself, and British drivers must take it more seriously than any other point in this guide. French law punishes flight from a police stop with remarkable severity: article L. 233-1 of the Code de la route provides that “Le fait, pour tout conducteur, d’omettre d’obtempérer à une sommation de s’arrêter émanant d’un fonctionnaire ou d’un agent chargé de constater les infractions et muni des insignes extérieurs et apparents de sa qualité est puni de deux ans d’emprisonnement et de 15 000 euros d’amende.” Two years of imprisonment and 15,000 euros for failing to stop when ordered by an identifiable officer, with additional penalties and consecutive sentencing on top. Panicking at blue lights because the registration is late turns a ticketable administrative delay into a criminal file with custody, a court date and a possible driving ban. Always stop, stay courteous, hand over the licence, the V5C or carte grise and whatever insurance evidence you hold, and argue the substance later in writing with a lawyer, never on the verge with the patrol. If language is a barrier, say so calmly, show the documents, and note the officers’ names, the time, the place and the reference number of any notice, because those details are the raw material of every successful challenge described below.
B. Challenging the ticket, the increased fine and the impound decision step by step
Every French traffic fine carries its challenge instructions on the notice itself, and the first rule is to read them before doing anything else, because the wrong move at the wrong time closes doors permanently. For a standard fixed fine arising from a fourth-class contravention such as circulation without registration, the route is the requête en exonération (the request for exoneration) or, after the increased-fine stage, the réclamation (the formal complaint) to the public prosecutor. Admissibility is formalistic to the point of brutality: article 529-10 of the Code of Criminal Procedure warns that “la requête en exonération prévue par l’article 529-2 ou la réclamation prévue par l’article 530 n’est recevable que si elle est adressée par lettre recommandée avec demande d’avis de réception, en utilisant le formulaire joint à l’avis d’amende forfaitaire”, accompanied by the supporting documents the article lists. Translation for a British keeper: send it by recorded delivery with return receipt (lettre recommandée avec accusé de réception), on the official form attached to the notice, with the exhibits, and keep the postal receipt. An email, a phone call to the fines centre, or a letter in English without the form is inadmissible, however strong the underlying argument. The valid grounds themselves are practical, not theoretical: the car was in fact registered by the date alleged, the ANTS receipt (accusé d’enregistrement) proves a timely application stuck in processing, the address on file was wrong through no fault of yours, or you were not the keeper at the material time, proved by the cession declaration and the fifteen-day seller record.
If the first notice was ignored or arrived at an old address, the file moves to the amende forfaitaire majorée, the increased fixed fine, which is an enforceable title with its own complaint window. Article 530 of the Code of Criminal Procedure provides that “Dans les trente jours de l’envoi de l’avis invitant le contrevenant à payer l’amende forfaitaire majorée, l’intéressé peut former auprès du ministère public une réclamation motivée”, and that complaint, where admissible, sends the case before the police court (tribunal de police) for a full hearing instead of an automatic collection. The thirty days run from the sending of the notice, not from your discovery of it, which is why the one-month address-update duty in article R. 322-7 is not bureaucratic decoration: keep the ANTS address current, open every letter from Rennes (the national fines centre), and diary the deadline the day the envelope arrives. Before the police court the argument shifts from form to substance. Produce the dated ANTS application receipt showing you applied within the month, the customs 846A or exemption proving the import was lawful, the COC or single-vehicle approval, the contrôle technique report, and the French insurance certificate with its start date. Judges regularly discharge or substantially reduce penalties where the file shows a genuine newcomer who applied promptly and was trapped by ANTS processing times, a missing manufacturer document or a customs delay, as opposed to a keeper who drove two years on GB plates without lifting a finger. Paying the reduced fine promptly while separately regularising the car is often the commercially sensible course for a clear-cut delay, but never pay the majorée without advice where you have a real defence, because payment can be treated as recognition and the complaint route, once open, is the only path to a judicial acquittal.
Impound and insurance cases need faster, parallel action because the car degrades and the fees grow every day. Demand the written impound order (procès-verbal de mise en fourrière) and check its stated legal basis, the authority that ordered it and the designated pound. Regularise immediately in the following order: French insurance with a certificate effective from a date you can prove, ANTS registration application with receipt, and contrôle technique appointment confirmation. Then apply in writing for release (mainlevée) to the ordering authority, attaching the three proofs, and contest any refusal before the administrative court where the order came from the prefect, or before the criminal court where it came from the prosecutor. For insurance prosecutions, build the file around the two edges the Versailles judgment identified: make the insurer prove any alleged intentional falsehood and its effect on the risk assessment, and produce your own subscription questionnaire, emails and cover notes showing what you actually declared. Where cover genuinely lapsed for a few days between the UK policy’s end and the French policy’s start, gather bank statements, the UK cancellation letter and the French subscription timestamp to frame the gap as negligence at worst, documented and cured, rather than a deliberate uninsured circulation. And throughout, keep one master folder, physical and scanned: V5C export section, ferry or transport invoice, customs 846A, ANTS receipts, COC, contrôle reports, insurance certificates, every fine notice with its envelope, and every recorded-delivery slip. French traffic litigation is won by the party whose folder is complete, and the British keeper whose folder tells a coherent story of a household that did everything in order is the one who walks out of the tribunal de police with a discharge or a symbolic penalty instead of the maximum.
Conclusion
Bringing a British car to a French life after Brexit is a perfectly lawful project, but it is an administrative project before it is a road trip. Notify the DVLA’s permanent export section and keep the V5C remainder. Clear customs and secure the 846A certificate or exemption before counting on any deadline. Apply to the ANTS within the month with identity, address, V5C, customs paper and conformity proof, and keep the application receipt as the most valuable document you own. Pass the French contrôle technique on the four-year then two-year rhythm through approved centres. Insure with a French company from the week you arrive and declare the car’s origin and every modification in writing. Update the file within a month of every house move. And if the police stop you, stop, cooperate, note everything, and challenge in writing by recorded delivery on the official form within the stated time, taking the thirty-day majorée complaint to the police court with a complete folder rather than an explanation. The statutes are demanding but predictable: registration within the month, insurance always, roadworthiness on schedule, and formal challenges through the prosecutor to the judge. Meet them in order and the GB plates become a brief transitional memory. Ignore them and the same car becomes the most expensive object in the drive, billing you daily from behind the pound fence while the fines multiply at your former address.
