You had two glasses of Bergerac at a village supper near Sarlat, waited an hour, and drove the ten minutes home along a road you know by heart. Halfway there, blue lights fill the mirror. The gendarmes are running a routine evening check, and the small tube they hold out changes your next twelve months: one reading over the limit, your pink UK photocard slipped into a sealed envelope, and a piece of paper telling you that you may not drive in France from this moment on. If you live in the Dordogne, the Charente, Brittany or the Luberon on a British passport, this scene is far more common than the expatriate forums admit, and the procedure that follows is nothing like an English fixed penalty. France runs two parallel tracks against you at once, an administrative track led by the préfet, meaning the State representative in the département who can suspend your right to drive within days, and a criminal track before the tribunal correctionnel, meaning the criminal court that tries mid-level offences, which can fine you, suspend you again, and enter a conviction on your French record. Your UK licence does not shield you, your British insurance habits do not apply, and every deadline runs in French from the night of the stop. This guide explains, step by step, what happens in the first seventy-two hours, how the roadside test can be challenged, what the criminal court will actually do to a British resident, and what a conviction means for your UK licence, your French points balance and your motor insurance.

I. I Have Just Been Stopped for Drink-Driving in France: What Happens to My Licence in the First 72 Hours?

A. How the Roadside Alcohol Test Works in France and Why Refusing It Makes Everything Worse

French drink-driving law starts from a lower limit than many British drivers expect, and the vocabulary matters from the first minute. The preliminary screening at the roadside is the dépistage, meaning the initial breath screening carried out with a handheld device, and the evidential measurement that follows is the vérification, meaning the formal verification of your alcohol level by an approved instrument or a blood sample. For an ordinary experienced driver, the line between lawful and unlawful sits at 0.50 grammes of alcohol per litre of blood, or 0.25 milligrammes per litre of exhaled air. Below that you drive on, possibly shaken but lawful. Between that line and the higher criminal line, you commit a serious traffic contravention punished by a fourth-class fine and an automatic loss of six points for a French licence holder. Article R. 234-1 of the Highway Code targets exactly this middle band: “Une concentration d’alcool dans le sang égale ou supérieure à 0,20 gramme par litre ou par une concentration d’alcool dans l’air expiré égale ou supérieure à 0,10 milligramme par litre et inférieure aux seuils fixés à l’article L. 234-1”. Note the 0.20 figure inside that text: it applies to probationary drivers, bus drivers and drivers already restricted to a car fitted with an alcohol interlock, so if you passed your test recently or drive with an éthylotest anti-démarrage, meaning an ignition interlock device that blocks the starter when alcohol is detected, your margin is less than half the normal one. For most British residents holding a full licence, the 0.50 line is the one that counts, and the gendarmes need no sign of drunkenness to act once the device shows it.

At or above 0.80 grammes per litre of blood, or 0.40 milligrammes per litre of exhaled air, you cross from a contravention into a délit, meaning a criminal offence tried by the criminal court rather than dealt with as a ticket. Article L. 234-1 of the Highway Code states the rule bluntly: “le fait de conduire un véhicule sous l’empire d’un état alcoolique caractérisé par une concentration d’alcool dans le sang égale ou supérieure à 0,80 gramme par litre ou par une concentration d’alcool dans l’air expiré égale ou supérieure à 0,40 milligramme par litre est puni de trois ans d’emprisonnement et de 9 000 euros d’amende”. Read that opening phrase carefully, because it answers the argument heard at every village bar: the offence exists, in the words of the same article, “Même en l’absence de tout signe d’ivresse manifeste”, meaning even where there is no outward sign of drunkenness at all. Driving perfectly straight, speaking clearly and passing every balance test counts for nothing once the measured level reaches the threshold. The same article adds two automatic consequences that surprise British drivers: your vehicle can be immobilised on the spot under the impounding rules, and the offence triggers by operation of law the loss of half the maximum points on a French licence, which in practice means six points gone before the court has even seen you.

The worst decision you can make at the roadside is to refuse the test in the belief that no measurement means no case. French law punishes refusal as harshly as the drink-driving itself. Article L. 234-8 of the Highway Code provides: “Le fait de refuser de se soumettre aux vérifications prévues par les articles L. 234-4 à L. 234-6 ou aux vérifications prévues par l’article L. 234-9 est puni de trois ans d’emprisonnement et de 9 000 euros d’amende”. Refusal also opens the same additional penalties as a positive result, including suspension or cancellation of your right to drive, and it hands the préfet clean grounds for an immediate administrative suspension, since the officer’s report will record that the statutory checks were offered and declined. There is one narrow situation where the measurement genuinely can be fought, and it concerns the machine itself. The evidential breath analyser, the éthylomètre, meaning the fixed or transported electronic device whose reading is used as evidence in court, must be of an approved type and periodically checked. On 13 May 2025 the Criminal Chamber of the Court of Cassation, France’s highest court for criminal matters, restated the rule in appeal number 24-86.012: “la recherche de la concentration d’alcool par l’analyse de l’air expiré est réalisée au moyen d’un appareil conforme à un type homologué et soumis à des vérifications périodiques”. In that case the appeal court had annulled the whole prosecution because the type-approval certificate for the Draeger device had expired, but the Court of Cassation quashed the acquittal, holding that “la vérification primitive après réparation constitue une vérification périodique permettant l’utilisation pendant un an supplémentaire de l’éthylomètre dont la validité de l’examen de type a pris fin sans être prorogée”. The lesson for your defence is precise rather than encouraging: challenges to the machine succeed only with hard metrology evidence about missed checks or an unrepaired device, never with a general complaint that the reading felt wrong. What you should always do, politely and on the record, is ask for the second breath measurement after the short statutory interval and, where the level is close to a threshold or you dispute the reading, request a blood sample as a counter-analysis, because a documented procedural request made that night is worth far more than an argument invented three months later.

Practical conduct in the first hour therefore follows a short checklist. Stay courteous and produce your UK photocard, your Withdrawal Agreement residence card or visa, and your insurance certificate without argument. Do not volunteer how much you drank, where, or when, beyond confirming your identity, because your statements are written into the procès-verbal, meaning the official written record drawn up by the officers that the court will treat as reliable unless cogent evidence contradicts it. Sign the papers you are asked to sign, but read the figures on the breath printout and note the exact times. Ask for the blood counter-test if the reading surprises you. And telephone a lawyer before any extended interview, because anything from this point can move into police custody, the garde à vue, meaning detention at the police station for questioning, where an interpreter must be provided if your French is limited and where early legal advice shapes the entire file.

B. How the Police Keep Your Licence on the Night and How the Préfet Suspends Your Right to Drive Within Days

The envelope your photocard went into is not a confiscation but a rétention, meaning the immediate short-term holding of your licence by the police, typically for seventy-two hours, which buys the administration time to decide. Within that window the file goes to the préfet, and for alcohol and drug cases requiring laboratory or evidential verification the window stretches to one hundred and twenty hours. Article L. 224-2 of the Highway Code sets the mechanism: “Le représentant de l’Etat dans le département doit, dans un délai de soixante-douze heures à compter de la rétention du permis de conduire prévue à l’article L. 224-1, ou dans un délai de cent vingt heures pour les infractions pour lesquelles les vérifications prévues aux articles L. 234-4 à L. 234-6 et L. 235-2 ont été effectuées, prononcer la suspension du permis de conduire lorsque”, followed by the listed alcohol cases. The official English-language service-public.fr guidance confirms the practice in plain terms: the prefect decides within seventy-two hours, or one hundred and twenty hours for alcohol and drug offences needing verification, and where those deadlines could not be met the prefect may still order suspension once informed by an offence report carrying a possible suspension penalty. In ordinary cases the maximum length of this administrative suspension is six months, and the notification letter arrives by recorded delivery or personal service, setting out the period and the appeal routes. From the moment of the roadside rétention you are forbidden to drive anywhere in France, including moving your car from the pound, and driving during the suspension is itself a criminal offence.

Two British-specific traps operate inside this administrative phase. The first concerns the physical UK licence in the prefecture’s drawer. Officers will retain a British photocard exactly as they retain a French one, and the prefecture’s order suspends your right to drive on French territory regardless of which country printed the card. You cannot defeat the order by producing a second document, ordering a replacement from Swansea, or arguing that a French prefect cannot touch a British licence: French territorial law governs driving on French roads, and the suspension attaches to the right to drive in France. The second trap concerns your residence status paperwork. If you hold a Withdrawal Agreement card, a long-stay visa, or a visitor status, the suspension does not directly cancel your residence right, but the criminal conviction that usually follows must be declared on certain renewal and naturalisation forms, and a recent drink-driving conviction colours any character assessment. Keep every notification, because the administrative dates will matter at sentencing, as explained below, and because a missing letter is the most common reason British drivers discover a suspension only at a second roadside check, which converts a manageable file into a far darker one.

Challenging the prefectural order is possible but narrow, and you must understand its limits before spending money on it. The order can be contested by an informal appeal to the prefect, the recours gracieux, meaning a written request asking the authority that signed the decision to reconsider it, alongside or followed by litigation before the administrative court, the tribunal administratif, meaning the court that reviews decisions of public authorities, including an urgent interim application, the référé-suspension, meaning the fast-track hearing asking the judge to halt the order while the main case is examined. The service-public.fr guidance warns expressly that your appeal does not prevent the prefect’s decision from applying, so you remain unable to drive while the judge considers the case. In practice the administrative judge intervenes only for a clear illegality, such as a missed deadline without a covering offence report, a suspension signed by an authority without power, or a decision with no statement of reasons, and even a victory may arrive after the suspension has been largely served. The medical dimension then takes over: for suspensions of six months or more you must pass a psychotechnical examination with an approved psychologist before the medical check, then attend the departmental medical commission, the commission médicale, meaning the panel of approved doctors that assesses fitness to drive after alcohol or drug offences, or an approved individual doctor for shorter cases. If that commission declares you unfit, the prefect extends the consequences until fitness is established, and a licence eventually reissued after a long suspension may carry a limited validity of six months or a year, forcing a fresh medical round. None of this replaces the criminal case running in parallel, and it is the criminal court that ultimately fixes your lasting position.

II. How Do I Get My Licence Back and Challenge the Decision as a British Driver?

A. How the Criminal Court Punishes Drink-Driving and How Your Administrative Suspension Counts Towards the Sentence

Most first-time drink-driving cases against resident drivers are steered into fast procedures that resolve within weeks, and you need to recognise which door you are walking through. The gentlest route is the composition pénale, meaning a settlement procedure proposed by the prosecutor for lower-level offending, where you agree to measures such as a fine, a short suspension or an awareness course without a full trial, though it still leaves a trace. The middle route is the comparution sur reconnaissance préalable de culpabilité, often called CRPC, meaning the guilty-plea hearing where you admit the facts before a judge who approves a negotiated penalty on the spot. The full route is a trial before the tribunal correctionnel, with witnesses, expert argument about the machine, and a reasoned judgment. Which route you are offered depends on your reading, your record, and whether you already hold a French criminal record entry, and a lawyer’s first job is often to push your file from the full trial list into the negotiated hearing where the outcome can be controlled. Never treat the summons, the convocation, meaning the formal notice ordering you to appear before the court on a fixed date, as optional correspondence: failure to attend means trial and sentence in your absence, and a British address on the file is no excuse the court will accept twice.

At sentencing the court disposes of a menu of additional penalties that go well beyond the headline fine. Article L. 234-2 of the Highway Code lists them, starting with the one that hurts a rural household most: “La suspension, pour une durée de cinq ans au plus, du permis de conduire, cette suspension ne pouvant pas être limitée à la conduite en dehors de l’activité professionnelle”. That final clause deserves emphasis, because English courts sometimes shape disqualifications around employment needs, whereas the French suspension for this offence cannot be ring-fenced to spare your commute or your working hours. The same article allows cancellation of the licence with a ban on reapplying for up to five years, community service, day-fines, a ban on driving certain motor vehicles even where no licence is needed, and a compulsory road-safety awareness course at your expense. In practice a first offence with a moderate reading and no accident usually draws a fine of several hundred euros, a suspension of a few months, and the course, while high readings, accidents, injuries, or repeat offending push the court towards cancellation, community service or imprisonment, including suspended terms that still stain the record. Your personal circumstances, stable residence, employment, family responsibilities, and evidence of abstinence or treatment since the stop, are the levers that move the sentence within these brackets, which is why gathering payslips, the employment contract, school certificates and proof of an alcohol-awareness initiative before the hearing is practical defence work rather than decoration.

The crucial accounting question, the one that decides the actual calendar date you drive again, is how the prefectural suspension interacts with the court’s suspension. Here the Court of Cassation has given drivers a clear and generous rule. Article L. 224-9 of the Highway Code provides: “La durée des mesures administratives s’impute, le cas échéant, sur celle des mesures du même ordre prononcées par le tribunal”. In a leading decision of 14 April 2021, appeal number 20-83.607, the Criminal Chamber applied this to a driver who had served a six-month prefectural suspension and then received a ten-month court suspension, restating the principle in these terms: “L’article L. 224-9 du code de la route prévoit que la durée des mesures administratives de suspension s’impute, le cas échéant, sur celles prononcées par le tribunal”. The same ruling extended the credit beyond the bare six months to the whole period during which the driver remained unable to drive for want of the medical fitness decision, holding that the maintained suspension counts too. Concretely, if the prefect suspends you for six months from January and the court in October suspends you for ten months, you do not serve sixteen months: the six months already served are deducted, and any extra months during which the administration kept you off the road pending the medical decision count as well. The mirror rule protects the acquitted: administrative measures ordered at the start of the case are treated as never having existed where the case ends in a dismissal or an acquittal, because, in the words of the same article, “Les mesures administratives prévues aux articles L. 224-1 à L. 224-3 et L. 224-7 sont considérées comme non avenues en cas d’ordonnance de non-lieu ou de jugement de relaxe”. Keep every prefectural letter and every medical notification, therefore, because the court needs the paper trail to compute the deduction, and errors in this arithmetic are common enough that a lawyer should verify the prosecutor’s proposed return date rather than accepting it.

Defences at trial fall into three families, and honesty about their odds saves you money. The first family attacks the measurement: missed periodic checks on the éthylomètre, an unrepaired device put back into service, confusion between the screening and evidential readings, or a denied request for a blood counter-test. As the May 2025 ruling shows, courts examine these arguments seriously but apply them strictly, and the prosecution usually produces the verification log that closes the point. The second family attacks the procedure: unlawful custody, missing interpreter where your French was plainly insufficient, or a burred chain of custody for a blood sample. These points require the custody record and the hearing transcript, and they succeed where the file shows a concrete breach rather than a theoretical one. The third family does not seek acquittal at all but negotiates the penalty: an unblemished record, a reading just over the threshold, immediate enrolment in a course, and proof that your household depends on your driving can halve a suspension or convert a cancellation into a suspension. One argument to discard immediately is the claim that Brexit puts you beyond French traffic law: the offence, the prefectural suspension and the court’s sentence apply to every driver on French soil, British passport or not, and the courtroom has heard that submission often enough to greet it with visible impatience.

B. What a French Conviction Means for Your UK Licence, Your French Points, and Your Motor Insurance

The post-Brexit licence position confuses even well-informed British residents, because the old European rules and the new third-country rules sit side by side. Under the current Highway Code, a licence issued by a country outside the European Union and the European Economic Area is recognised in France for one year after you take up normal residence, and during that year it may be exchanged for a French licence without sitting the French test. Article R. 222-3 of the Highway Code states: “Tout permis de conduire national, en cours de validité, délivré par un Etat ni membre de l’Union européenne, ni partie à l’accord sur l’Espace économique européen, peut être reconnu en France jusqu’à l’expiration d’un délai d’un an après l’acquisition de la résidence normale de son titulaire”. The sting sits in the final sentence of the same article: “Au terme de ce délai, ce permis n’est plus reconnu et son titulaire perd tout droit de conduire un véhicule pour la conduite duquel le permis de conduire est exigé”. Since Brexit, the United Kingdom is precisely such a third country, subject to the bilateral exchange arrangements that allow swap applications through the ANTS online portal, the Agence nationale des titres sécurisés, meaning the national agency that processes licences, registrations and identity documents. The practical consequence is stark: if you settled in France years ago and never exchanged your UK photocard, you may already have been driving on an unrecognised licence before the drink-driving stop, and the stop will expose it. Driving without a valid licence is its own offence: Article L. 221-2 of the Highway Code provides that “Le fait de conduire un véhicule sans être titulaire du permis de conduire correspondant à la catégorie du véhicule considéré est puni d’un an d’emprisonnement et de 15 000 euros d’amende”. Check your exchange position the week you read this, not the week the gendarmes check you.

For British drivers who did exchange in time, or who must exchange after the case, the offence accelerates everything. The Code has long provided that a European licence holder who commits an offence on French soil carrying a restriction, suspension, withdrawal or points loss must swap the licence for a French one so the measure can be applied. Article R. 222-2 of the Highway Code states: “L’échange d’un tel permis de conduire contre le permis français est obligatoire lorsque son titulaire a commis, sur le territoire français, une infraction au présent code ayant entraîné une mesure de restriction, de suspension, de retrait du droit de conduire ou de retrait de points”. The prefecture applies the same logic in practice to British licences after a drink-driving measure: you will be required to go through the ANTS exchange so that the suspension, the points withdrawal and any cancellation bite on a French document. The British side of the Channel looks at the matter through its own lens: the GOV.UK guidance for UK licence holders living in the European Union, available at Driving in Europe: UK licence holders living in the EU, explains that once resident you drive under the host country’s rules and should exchange or register your licence locally rather than relying on the UK document indefinitely. Nothing in that guidance overrides a French suspension, and no letter from Swansea restores a right that a French prefect and a French court have removed on French territory.

The French points system then produces its own surprise for British holders. France operates a points licence: every French licence carries a balance, reduced automatically with each points-bearing offence. Article L. 223-1 of the Highway Code states: “Le permis de conduire est affecté d’un nombre de points. Celui-ci est réduit de plein droit si le titulaire du permis a commis une infraction pour laquelle cette réduction est prévue”. Drink-driving at the délit level removes six points by operation of law, and a new French licence issued after exchange starts with a balance that the offence immediately depletes. The United Kingdom does not import French points onto the UK counterpart, and France does not export them to Swansea, but that symmetry helps you less than it seems: what counts is the territorial right to drive, and a zero or negative balance on the French side means no lawful driving in France even if the UK card looks untouched in your wallet. Repeat offending can therefore push you into cancellation and a full re-examination, the repasse du permis, meaning the obligation to resit the theory and practical driving tests after a court-ordered cancellation, a humiliation that several established British residents undergo each year in examination centres from Périgueux to Perpignan.

Insurance is where the financial damage often exceeds the fine, and British assumptions about comprehensive cover mislead. French law makes motor liability insurance compulsory for any vehicle in circulation. Article L. 211-1 of the Insurance Code provides that the person liable “doit, pour faire circuler celui-ci, être couverte par une assurance garantissant cette responsabilité, dans les conditions fixées par décret en Conseil d’Etat”. Your insurer must still compensate third-party victims even where you drove drunk, because victim protection is a matter of public policy, but the policy almost invariably gives the insurer a contractual action to recover the sums paid from a driver convicted of drink-driving, the recours de l’assureur, meaning the insurer’s claim back against its own policyholder after paying the victims. In a serious injury file that recovery can reach tens or hundreds of thousands of euros, dwarfing the criminal fine. Separately, damage to your own car is typically excluded where the driver was over the limit, so the overturned vehicle in the ditch is yours to pay for. Finally, expect the renewal arithmetic to punish you for years: the insurer may treble the premium, impose an excess measured in thousands, or simply decline renewal, and the French information exchange between insurers means a London-based policy written for a French-resident risk will not rescue you. Notify your insurer promptly through a formal declaration, keep proof of posting, and take advice before signing any settlement the insurer slides across the table while the criminal case is still open. And remember the immediate physical risk that started the file: the officers who stopped you could have had the car immobilised and impounded on the spot, since Article L. 325-1 of the Highway Code allows vehicles to “être immobilisés, mis en fourrière, retirés de la circulation et, le cas échéant, aliénés ou livrés à la destruction” where road safety or the victims’ right to compensation is at stake. Storage charges accrue daily, and release requires proof that a sober licensed driver collects the vehicle.

Conclusion

A drink-driving stop in France subjects a British driver to a machine with little tolerance for argument, an administration that suspends first and discusses later, and a criminal court whose toolbox runs from negotiated pleas to cancellation and imprisonment. The defences that work are technical and documentary: the calibration log of the éthylomètre, the seventy-two and one-hundred-and-twenty-hour clocks on the prefectural order, the medical commission file, and the exact arithmetic that deducts the administrative months from the judicial months. The traps that destroy files are distinctively British: an unexchanged photocard that was already unrecognised before the stop, a belief that the UK document overrides a French suspension, and an insurance policy read with English eyes. Treat the first night as the decisive one: request the counter-test, note every time and figure, keep every letter, and instruct a lawyer before the first hearing rather than after the first sentence. The French system rewards the prepared driver with shorter suspensions and preserved licences, and it shows no leniency to the driver who assumed Brexit had made French roads English.
