You were driving down to the Dordogne, or cutting along the A26 back to the Tunnel, when a white flash went off beside a grey box on the hard shoulder. Nobody stopped you, nobody asked for your licence, and you thought no more about it until a brown envelope from France landed on your doormat in Kent, or an email from your hire company told you that a French fine had been matched to your rental, sometimes with an administration fee added under your rental agreement. The letter is therefore not a scam to be binned, and it is not the end of the story either. It is the opening of a strict timetable in which paying within fifteen days can reduce the bill to 45 euros instead of 68, or 90 instead of 135, designating the real driver can move the liability, and doing nothing for forty-five days increases the penalty automatically. This guide explains, for British licence holders in particular, who French law holds liable when a camera flashes, what a speeding case really costs and when it turns criminal, how to pay or to name another driver when the notice reaches a United Kingdom address, and how to challenge the penalty without falling into the traps that defeat most appeals. Every French term is explained as it appears, and every decisive rule is tied to the exact statute or court decision that creates it.

I. I was flashed by a speed camera in France — what happens next and what do I risk?

A. Who pays when the camera never stops the driver?

A speed camera does not identify a driver; it photographs a number plate. French law draws a sharp line from that fact. The starting rule, in article L121-1 of the Highway Code (Code de la route), is personal: “Le conducteur d’un véhicule est responsable pénalement des infractions commises par lui dans la conduite dudit véhicule.” In plain English, the person behind the wheel is criminally responsible for the driving offences they commit. But cameras cannot stop the wheel, so a second rule takes over for automated offences. By way of exception, article L121-3 of the Highway Code provides that “le titulaire du certificat d’immatriculation du véhicule est redevable pécuniairement de l’amende encourue pour des infractions dont la liste est fixée par décret en Conseil d’Etat, à moins qu’il n’établisse l’existence d’un vol ou de tout autre événement de force majeure ou qu’il n’apporte tous éléments permettant d’établir qu’il n’est pas l’auteur véritable de l’infraction.” The titulaire du certificat d’immatriculation is the registered keeper of the vehicle, the person named on the French registration document still commonly called the carte grise; redevable pécuniairement means financially liable for the fine, as opposed to criminally guilty; and force majeure means an unforeseeable event beyond anyone’s control. Speeding recorded by automatic device is on the list, so the keeper pays unless they prove theft, force majeure, or produce material showing they were not the driver.

The Cour de cassation, the supreme court for criminal matters, polices that boundary strictly. On 9 September 2025, in decision no. 24-87.195 (ECLI:FR:CCASS:2025:CR00981), the criminal chamber restated that “Selon le premier de ces textes, le titulaire du certificat d’immatriculation du véhicule est redevable pécuniairement de l’amende encourue pour la contravention d’excès de vitesse, à moins qu’il n’établisse l’existence d’un vol ou de tout autre événement de force majeure, ou qu’il n’apporte tous éléments permettant d’établir qu’il n’est pas l’auteur véritable de l’infraction.” The lower court had acquitted a keeper who said his plates might have been stolen while he was on holiday in Morocco, reasoning that it was “perfectly plausible” the flashed car was not his. The supreme court quashed that reasoning outright: “En se déterminant ainsi, par des motifs hypothétiques insuffisants à écarter la responsabilité pécuniaire au titre de laquelle le prévenu était uniquement recherché, le tribunal n’a pas justifié sa décision.” Hypotheses do not defeat keeper liability. A British owner of a French-registered second-home car who simply says “it could have been anyone” will lose; a theft report (dépôt de plainte, the formal criminal complaint filed with the police), a destruction certificate, a sale declaration, or the full identity and licence details of the real driver is what the text demands.

A second decision shows the other side of the same line, and it matters particularly to anyone hiring a car. On 18 November 2025, in no. 25-83.480 (ECLI:FR:CCASS:2025:CR01484), the criminal chamber dealt with the hirer of a vehicle convicted of driving the wrong way down a street (circulation en sens interdit) recorded by an automatic device. The court recalled that “Selon le premier de ces textes, le conducteur d’un véhicule est responsable pénalement des infractions commises par lui dans la conduite dudit véhicule,” then held that where the offender was not stopped at the time, “la valeur probante du procès-verbal constatant l’infraction est limitée, en l’absence de verbalisation immédiate du contrevenant, à la caractérisation du comportement incriminé et à l’identification du véhicule en cause, l’identité du conducteur de ce dernier au moment des faits demeurant dès lors incertaine.” The procès-verbal is the official written record of the offence, and verbalisation immédiate means being stopped and reported on the spot. The hirer had denied being the driver both in his exemption request and before the court, yet had been convicted as the driver on the strength of the report alone. The supreme court quashed the conviction: without an on-the-spot stop, the report proves the manoeuvre and the vehicle, not who was driving, and the court should have considered financial liability as keeper rather than personal guilt as driver. For a British hirer the lesson is symmetrical with keeper liability. If you were genuinely not driving, deny it consistently from the first form and supply the real driver’s details, because silence leaves only the financial-liability route. And the authorities cannot turn a plate photograph into a named driver without more.

Hire cars follow the same logic with one extra link in the chain. Article L121-2 of the Highway Code, for parking and similar cases, and article L121-3, for radar speeding, both move the financial liability onto the hirer (locataire) where the vehicle was hired out, under the same defences. That is why the hire company writes to you weeks later: the enforcement system asks it who held the car at the flash time, it names you, and the avis de contravention, the formal notice of the offence setting out the fixed penalty to pay, is reissued in your name to your home address. The hire company may also debit an administration fee under your rental agreement for handling the paperwork. If the hire company debits such a fee, that dispute lies between you and the company under the rental agreement; the fine itself follows the forty-five-day procedure. Company cars are harsher still, as Part II explains: article L121-6 of the Highway Code makes failure to designate the employee driver a separate offence, punished far more heavily than the speeding itself.

One question worries British readers most: the points. A decision holding the keeper merely financially liable “ne donne pas lieu à inscription au casier judiciaire, ne peut être prise en compte pour la récidive et n’entraîne pas retrait des points affectés au permis de conduire”, in the words of article L121-3: no entry on the criminal record (casier judiciaire), no counting as a previous offence (récidive), no withdrawal of licence points. The same protection covers the deposit lodged with a challenge: article 529-10 of the Code of Criminal Procedure (Code de procédure pénale) provides that “cette consignation n’est pas assimilable au paiement de l’amende forfaitaire et ne donne pas lieu au retrait des points du permis de conduire prévu par le quatrième alinéa de l’article L. 223-1 du code de la route.” Article L223-1 of the Highway Code runs the French points system (permis à points), under which “Lorsque le nombre de points est nul, le permis perd sa validité”: when the points reach zero, the licence loses validity. If you hold a French licence and are convicted as the driver, points go under article L223-1. Paying as keeper, in any event, leaves no French criminal record. But do not confuse that with impunity, which is the subject of the next section: the money penalties are real, they grow fast, and at high speeds the case stops being a mere ticket.

B. What does a speeding ticket really cost, and when does it become a criminal case?

Ordinary speeding recorded by camera is a contravention, a minor offence dealt with by fixed penalty without a court hearing. Article R413-14 of the Highway Code states that “le fait, pour tout conducteur d’un véhicule à moteur, de dépasser de moins de 50 km/h la vitesse maximale autorisée fixée par le présent code ou édictée par l’autorité investie du pouvoir de police est puni de l’amende prévue pour les contraventions de la quatrième classe.” The one exception helps small excesses on fast roads: below 20 kilometres per hour over a limit above 50, the case drops to a third-class petty offence. The standard scale is set by regulation: article R49 of the Code of Criminal Procedure fixes “4° 68 euros pour les contraventions de la 3e classe ; 5° 135 euros pour les contraventions de la 4e classe.” Speed, in other words, is priced in two bands for camera cases: a modest excess on a motorway or dual carriageway sits at 68 euros, while anything from 20 over, or any excess in a 30 or 50 zone, sits at 135 euros. Exceeding the limit by 30 or more also exposes the driver to complementary penalties (peines complémentaires, additional sanctions a court may add): suspension of the French driving entitlement for up to three years, a ban on driving certain motor vehicles for up to three years, and a compulsory road-safety awareness course at the offender’s expense.

Speed then changes the arithmetic twice, once downwards and once upwards. Pay at once and the penalty shrinks. Article 529-7 of the Code of Criminal Procedure provides that for listed second-to-fifth-class road contraventions except parking, “l’amende forfaitaire est minorée si le contrevenant en règle le montant dans les conditions prévues par l’article 529-8”, and article 529-8 gives “un délai de quinze jours à compter de la constatation de l’infraction ou, si l’avis de contravention est ultérieurement envoyé à l’intéressé, dans le délai de quinze jours à compter de cet envoi”, adding that “En cas de non-paiement de l’amende forfaitaire minorée dans les conditions prévues ci-dessus, le contrevenant est redevable de l’amende forfaitaire.” The reduced (minorée) scale in article R49-9 runs “2° 45 euros pour les contraventions de la troisième classe ; 3° 90 euros pour les contraventions de la quatrième classe.” Wait too long and it swells: “A défaut de paiement ou d’une requête présentée dans le délai de quarante-cinq jours, l’amende forfaitaire est majorée de plein droit et recouvrée au profit du Trésor public en vertu d’un titre rendu exécutoire par le ministère public,” in the words of article 529-2 of the Code of Criminal Procedure. The Trésor public is the state revenue service that recovers public debts, and the ministère public is the prosecuting authority whose enforceable order (titre exécutoire) turns the increased sum into a recoverable debt automatically (de plein droit). The increased (majorée) scale in article R49-7 runs “4° 180 euros pour les contraventions de la troisième classe ; 5° 375 euros pour les contraventions de la quatrième classe.” Article R49-6 adds that the increased notice states that “en cas de paiement volontaire de l’amende forfaitaire majorée dans le délai d’un mois à compter de sa date d’envoi, le montant des sommes dues sera diminué de 20 %.” None of this needs a judge; it is arithmetic driven by dates, which is why Part II dwells on deadlines.

At 50 kilometres per hour or more over the limit, the file leaves the world of tickets entirely. Article L413-1 of the Highway Code provides that “le fait, pour tout conducteur d’un véhicule à moteur, de dépasser de 50 kilomètres à l’heure ou plus la vitesse maximale autorisée est puni de trois mois d’emprisonnement et de 3 750 euros d’amende.” That is a délit, a criminal offence tried in the criminal court, carrying up to three months’ imprisonment and a 3,750 euro fine. Paragraph IV nonetheless preserves a settlement route: “Dans les conditions prévues aux articles 495-17 à 495-25 du code de procédure pénale, l’action publique peut être éteinte, y compris en cas de récidive, par le versement d’une amende forfaitaire d’un montant de 300 euros.” The same article adds vehicle confiscation, which is compulsory on a repeat offence although “la juridiction peut toutefois ne pas prononcer cette peine, par une décision spécialement motivée”, licence suspension of up to three years without any restriction to non-professional driving, a driving ban of up to five years, a paid awareness course, and even cancellation of the licence with up to three years before a new one may be sought. The provision also wipes out half the points of a French licence by operation of law. A British driver caught at 180 on an empty autoroute limited to 130 is therefore facing a criminal prosecution, albeit one that may still be extinguished by the fixed-penalty route in paragraph IV, and should take legal advice before answering anything.

Drivers stopped at the roadside meet a different procedure again, based on residence rather than nationality. Article L121-4 of the Highway Code provides that “Sauf cas de versement immédiat d’une amende forfaitaire ou d’une amende forfaitaire minorée, lorsqu’elles sont respectivement applicables, lorsque l’auteur d’une infraction se trouve hors d’état de justifier d’un domicile ou d’un emploi sur le territoire français ou d’une caution agréée par l’administration habilitée à percevoir les amendes garantissant le paiement éventuel des condamnations pécuniaires encourues, le véhicule ayant servi à commettre l’infraction pourra être retenu jusqu’à ce qu’ait été versée au comptable public compétent ou à un agent mentionné à l’article L. 130-4 porteur d’un carnet de quittances à souches une consignation dont le montant est fixé par arrêté.” The consignation is a security deposit guaranteeing payment, and the caution agréée is a guarantee body approved by the administration, such as a motoring organisation. “La décision imposant le paiement d’une consignation est prise par le procureur de la République, qui est tenu de statuer dans le délai maximum de vingt-quatre heures après la constatation de l’infraction. Le véhicule peut être mis en fourrière si aucune de ces garanties n’est fournie par l’auteur de l’infraction et les frais en résultant sont mis à la charge de celui-ci.” The procureur de la République is the local public prosecutor, who must decide within twenty-four hours of the offence, and the fourrière is the official vehicle pound. In short: no French address, job, or approved guarantee, and no on-the-spot payment, means the car is held until the deposit is paid, the prosecutor decides within a day, and the pound with its storage costs follows otherwise. The same statute therefore governs the British tourist stopped at the roadside and the French driver alike: residence, not nationality, decides the procedure. A British resident with a French home or job follows the postal route instead, exactly like a French driver. Either way, the flash is only the beginning of the paper chain, and the next part follows that chain to a United Kingdom letterbox.

II. I received the French fine at my UK address — how do I pay it or challenge it?

A. How do I pay, designate another driver, or deal with a hire car or company car?

Start with the envelope itself. The avis de contravention states the offence, the speed measured, the standard fixed penalty, and the final date for payment or challenge. Article 529-1 of the Code of Criminal Procedure gives “quarante-cinq jours qui suivent la constatation de l’infraction ou, si cet avis est ultérieurement envoyé à l’intéressé, dans les quarante-cinq jours qui suivent cet envoi”: forty-five days from the offence or, where the notice is posted later, forty-five days from posting. The notice itself sets out how to pay and whether the fifteen-day reduced rate is still available, so use the stated payment method at once and keep the receipt. For a British addressee the posting date matters more than the arrival date, because the forty-five days run from posting. If the notice never arrived at all and the first letter is the increased penalty, do not pay the increased sum blindly: the remedies in section B exist precisely for that situation.

Where someone else was driving, French procedure invites you to say so rather than to pay for them. The notice encloses a designation form (formulaire de requête en exonération, the standard form for requesting exemption), and for camera cases article 529-10 of the Code of Criminal Procedure makes the exemption request or later complaint admissible by recorded delivery letter (lettre recommandée avec demande d’avis de réception, registered post with a signed receipt proving delivery) using that enclosed form, with either one of a closed list of documents, “1° Soit de l’un des documents suivants”: the police report for theft, plate usurpation or vehicle destruction; a signed letter giving the full identity, address and driving-licence reference of the person who was probably driving; the sale declaration with its registration acknowledgement; or the automated-driving-system certificate; “2° Soit d’un document démontrant qu’il a été acquitté une consignation préalable d’un montant égal à celui de l’amende forfaitaire dans le cas prévu par le premier alinéa de l’article 529-2, ou à celui de l’amende forfaitaire majorée dans le cas prévu par le deuxième alinéa de l’article 530”: or, alternatively, proof that the matching deposit has been paid. Name the real driver completely and accurately, because an incomplete designation fails and leaves you liable as keeper. A spouse who flashes your French-registered car while you stayed in London is the classic case: designate promptly with licence number, and the file moves to them. Give accurate, consistent details: an incomplete or contradictory designation fails and leaves you liable as keeper.

Hire cars add a practical layer to the same legal mechanism. The hirer is the person pursued, as explained above. The hire company may also debit an administration fee under the rental agreement for handling the enforcement paperwork. If the hire company debits such a fee, that dispute lies between you and the company under the rental agreement; the fine itself follows the forty-five-day procedure. Then treat the reissued notice exactly like any other: forty-five days, designation if someone else drove the hired car, challenge if the facts are wrong. Keep the rental agreement, the handover inspection sheet, and any additional-driver slip, because they prove who held the car at the flash time if the company named the wrong lead driver. Where the flash involves a British-registered car driven by several family members on holiday, agree immediately on who was driving and designate once, consistently, rather than sending contradictory letters.

Company cars deserve a red flag of their own, because the separate designation duty carries a price the supreme court has now confirmed twice. Article L121-6 of the Highway Code requires that where an offence recorded by automated device was committed with a company vehicle, “le représentant légal de cette personne morale doit indiquer, par lettre recommandée avec demande d’avis de réception ou de façon dématérialisée, selon des modalités précisées par arrêté, dans un délai de quarante-cinq jours à compter de l’envoi ou de la remise de l’avis d’infraction, à l’autorité mentionnée sur cet avis, l’identité et l’adresse de la personne physique qui conduisait ce véhicule, à moins qu’il n’établisse l’existence d’un vol, d’une usurpation de plaque d’immatriculation ou de tout autre événement de force majeure.” The représentant légal is the company’s legal representative, and the notice goes to the authority shown on it. “Le fait de contrevenir au présent article est puni de l’amende prévue pour les contraventions de la quatrième classe ou, lorsque l’infraction mentionnée au premier alinéa est un délit, de l’amende prévue pour les contraventions de la cinquième classe.” On 20 May 2025, in no. 24-86.765 (ECLI:FR:CCASS:2025:CR00656), the file had begun with speeding of under 20 kilometres per hour recorded by the automated centre on 5 January 2023. The notice was paid on 1 February 2023 without the driver being named, so on 17 May 2023 the company received a second notice, this time for failing to disclose the driver’s identity and address. An ordonnance pénale, a criminal order made without a hearing, held it liable to 135 euros for that non-disclosure, the company opposed the order, and the police court confirmed a 135 euro fine. The criminal chamber recalled that “Selon ce texte, en cas de condamnation d’un contrevenant qui a formulé une requête en exonération d’amende forfaitaire, l’amende prononcée ne peut être inférieure à celle qui aurait été due si l’intéressé n’avait pas présenté de réclamation”, that is article 530-1 of the Code of Criminal Procedure, and held: “En l’espèce, la prévenue, qui avait formé une requête en exonération de l’amende forfaitaire due pour la contravention au code de la route qui lui était reprochée, a été condamnée à une amende de 135 euros”, yet “le montant de l’amende ne pouvait être inférieur à celui de l’amende forfaitaire prévue pour les personnes morales, soit 675 euros”, so “le tribunal de police a méconnu le texte susvisé” and the fine was fixed at 675 euros with no retrial. On 13 January 2026, in no. 25-82.876 (ECLI:FR:CCASS:2026:CR00037), a road offence recorded on 25 May 2022 involving a company-held vehicle produced the same sequence: payment without naming the driver, a non-disclosure notice on 7 October 2022, an exemption request, a criminal order finding non-disclosure at 675 euros, opposition, and a police-court fine of 135 euros. The court said it again: “Selon l’alinéa 2 de ce texte, en cas de condamnation d’un contrevenant qui a formé un recours contre une amende forfaitaire, l’amende prononcée ne peut être inférieure à celle qui aurait été due si l’intéressé n’avait pas présenté de réclamation”, and “En prononçant ainsi, alors lors que le montant de l’amende ne pouvait être inférieur à celui de l’amende forfaitaire encourue pour les personnes morales, soit 675 euros, le tribunal de police a méconnu le texte susvisé.” Two lessons follow for British businesses running French-registered cars. Note the narrow exception in the second paragraph of article L121-6: where a natural person registered the vehicle as a legal entity, “l’obligation prévue au même premier alinéa est alors réputée satisfaite si le titulaire du certificat d’immatriculation ou le détenteur du véhicule justifie, dans le même délai et selon les mêmes modalités, que le véhicule est immatriculé à son nom.” Name the driver within the forty-five days, subject to the sole-trader exception below, and never assume that challenging will reduce the bill: once a challenge is lodged and fails, article 530-1 sets a floor at the fixed or increased penalty according to the route taken, and “En cas de condamnation, l’amende prononcée ne peut être inférieure au montant prévu à l’alinéa précédent augmenté d’une somme de 10 %” in consignation cases.

B. How do I challenge the fine, and which deadlines kill most appeals?

A challenge (requête en exonération, the reasoned request for exemption sent within the forty-five days) must be reasoned, on the enclosed form, by registered post with proof of delivery, to the department shown on the notice, using one of the two admissibility routes article 529-10 provides: the listed documents or the matching deposit. The department forwards it to the prosecuting authority. Two outcomes follow: the prosecutor drops the case, or the case goes to the police court (tribunal de police, the court that tries minor offences), seized under article 531 of the Code of Criminal Procedure by direct summons among other routes. The well-founded challenges are narrow: mistaken plate or vehicle, theft or cloned plates proved by a prompt complaint, sale proved by the registered sale declaration, or designation of the true driver with full details. The unusable ones are familiar: “I did not see the sign”, “everyone was speeding”, “my speedometer reads low”, or a bare “it was not me” with nothing attached, which the 9 September 2025 decision above shows a court will reject. Where the offence is serious enough to reach court and you live in Britain, consider instructing a French lawyer to handle the hearing.

The twin danger of any challenge is the floor rule already quoted twice: contest and lose, and the court cannot go below what the fixed penalty would have been. A challenge is therefore a calculated step, worth taking on theft, cloning, sale, or solid designation evidence, and worth pricing honestly elsewhere: “En cas de condamnation, l’amende prononcée ne peut être inférieure au montant de l’amende ou de l’indemnité forfaitaire dans les cas prévus par le premier alinéa de l’article 529-2”, nor below the increased fixed penalty on the increased-penalty routes. File the wrong admissibility route, a bare letter where the documents or the deposit were required, and the challenge is declared inadmissible without ever being examined, which is how careful drivers lose winnable cases. The notice and its enclosed form show which of the two routes your case requires, so follow them exactly.

Unpaid notices follow their own escalator. Under article 529-2, silence for forty-five days produces automatic increase and recovery on the prosecutor’s enforceable order. The increased notice (avis d’amende forfaitaire majorée) then opens a complaint (réclamation motivée, the reasoned complaint against the increased penalty) within thirty days of its posting, which cancels the enforceable order for the contested sum. Article 530 of the Code of Criminal Procedure extends that complaint “tant que la peine n’est pas prescrite, s’il ne résulte pas d’un acte d’exécution ou de tout autre moyen de preuve que l’intéressé a eu connaissance de l’amende forfaitaire majorée”, meaning as long as the penalty is not time-barred, where no enforcement step or other evidence shows you knew of the increased fine. But camera cases carry the sting in the tail: “S’il s’agit d’une contravention au code de la route, la réclamation n’est toutefois plus recevable à l’issue d’un délai de trois mois lorsque l’avis d’amende forfaitaire majorée est envoyé par lettre recommandée à l’adresse figurant sur le certificat d’immatriculation du véhicule.” Three months from posting by registered letter to the keeper’s address, and the door shuts, unless you prove you had declared your change of address to the registration service before expiry, in which case “le contrevenant n’est redevable que d’une somme égale au montant de l’amende forfaitaire s’il s’en acquitte dans un délai de quarante-cinq jours, ce qui a pour effet d’annuler le titre exécutoire pour le montant de la majoration.”

That registered-letter machinery follows article 530 directly: where the increased notice goes by registered letter to the keeper’s address, three months from posting close the complaint route unless the keeper proves an earlier change-of-address declaration. For a British keeper this bites in two familiar ways. Move house in the United Kingdom between the holiday and the letter, and the registered notice goes to the old address while time runs. Sell the French-registered car without registering the sale, and the next keeper’s flashes land on you until the sale declaration proves otherwise. So act in this order on any increased notice: check the posting date against the three months, declare or evidence the address position at once, and pay the standard sum inside the forty-five days rather than arguing the increase by phone, which suspends nothing.

Conclusion

A French speed camera sets a paper machine in motion, not a negotiation. The keeper pays unless theft, force majeure, or the true driver’s full details are proved with documents; the report alone, without an on-the-spot stop, proves the car’s behaviour but not who drove; the standard bill is 68 or 135 euros, cut to 45 or 90 for payment within fifteen days and raised to 180 or 375 for delay; and 50 kilometres per hour over turns the ticket into a criminal prosecution. For the British addressee the discipline is the same: calendar the forty-five days from posting, use the enclosed form by registered post with the documents or the deposit, designate consistently, and use the three-month route the moment an increased penalty appears. Done promptly, most camera cases end with a modest payment or a clean transfer to the real driver. Done late, the same case ends at the police court with the failed-challenge floor under it. Keep the notice, the rental agreement or sale papers, the postal receipts, and the payment proof together; they are the file on which everything turns. The United Kingdom government’s driving abroad overview is the starting point for the British side of any trip, and the French statutes and decisions cited above are the rules of the French side. Between the two, a flashed British driver who acts within the deadlines has every tool needed to pay fairly or to challenge properly.
