Driving after consuming alcohol is one of the most severely punished offences under the Code de la route (French Highway Code). Whether you are an experienced driver, a novice driver on a permis probatoire (probationary licence), or a foreign resident travelling on French roads, no one is deemed to be ignorant of the strictness of the law in this area. Faced with a complex legal framework that oscillates between administrative contraventions (minor offences/fines) and criminal délits (misdemeanours), it is essential to know your exact rights, the applicable limits, and the penalties incurred to avoid dramatic consequences on your professional and personal life.

French law distinguishes between two levels of driving under the influence offences: the contravention (handled through administrative channels and fixed fines) and the délit (which falls under the jurisdiction of the Tribunal correctionnel or Criminal Court). Alcohol concentration levels are measured either per litre of blood (via a blood test) or per litre of exhaled air (via a breathalyser).
For the majority of drivers, the prohibited threshold begins as soon as the alcohol concentration reaches 0.50 g per litre of blood.
French legislation is even stricter for drivers in their probationary period (holders of a driving licence for less than 3 years, or less than 2 years if they completed the conduite accompagnée or supervised driving scheme) as well as for public transport drivers.
The punitive framework relies primarily on the Code de la route:
---
Sanctions are progressive and depend on the severity of the offence observed by law enforcement.
If you fall within the contravention range, you risk:
If the criminal threshold is crossed, the offence enters the criminal domain. The maximum theoretical penalties are particularly heavy:

To better understand the practical application of these rules, here are two simulations of common situations on French roads.
Thomas obtained his driving licence 10 months ago (probationary period, initial capital of 6 points). During a police check on a Saturday night, his breathalyser test reveals a level of 0.26 mg of exhaled air (equivalent to 0.52 g of alcohol per litre of blood).
Sophie, a driver for 15 years with a full balance of 12 points, is stopped leaving a restaurant. Her level is measured at 0.45 mg of exhaled air (equivalent to 0.90 g of alcohol per litre of blood).

When a breathalyser test is positive, the administrative and judicial procedure is triggered immediately according to a strict protocol.
1. Initial Screening: Law enforcement officers perform an initial test using an éthylotest (breathalyser bag or electronic device). If the indicator turns red, a suspicion of alcohol consumption is established.
2. Quantitative Verification: You are asked to blow into a precision breathalyser (éthylomètre) or undergo a blood test at the hospital. This second measurement is the legally binding one. A second breath sample can be requested by the driver; it is highly recommended to ask for it, as the law requires the authorities to record the level most favourable to the driver.
3. Retention of the Driving Licence: If the level is criminal (above 0.80 g/l), law enforcement officers immediately retain (rétention) your physical licence for a maximum duration of 120 hours (5 days). The vehicle is generally impounded (immobilisé) and sent to the fourrière (car pound) if no sober passenger can take the wheel.
4. The Prefectural Decision (Arrêté 3F): Within this 120-hour window, the préfet of the department generally issues a temporary suspension order (arrêté de suspension provisoire) for the licence (often for a duration of 3 to 6 months). This order is notified to you by registered mail or by the police services.
5. Judicial Summons: Subsequently, you will receive a summons to appear in court. This may take the form of an Ordonnance pénale (penal order), a Comparution sur reconnaissance préalable de culpabilité (CRPC, the French equivalent of a guilty plea/plea bargain), or a standard summons before the Tribunal correctionnel.
6. Recovering the Licence: At the end of the suspension period, to recover your licence, you must undergo a mandatory medical examination before the prefectural medical commission (commission médicale), often supplemented by psychotechnical tests if the suspension exceeds 6 months.

No, it is extremely risky. For drivers on a probationary licence, the limit is set at 0.20 g/l of blood. A single standard drink (of beer, wine, or spirits served in a bar) raises the blood alcohol level to between 0.20 g/l and 0.30 g/l depending on body mass. Therefore, the tolerance is practically zero drinks.
Administrative suspension is an emergency measure taken by the préfet within 120 hours of the roadside check, for a duration of 1 to 6 months (sometimes 12 months). Judicial suspension is ordered later by a judge during the court appearance. The months of administrative suspension already served are deducted from the sentence handed down by the judge.
No, not in cases of drunk driving. The permis blanc (an arrangement allowing driving for serious professional reasons) is strictly excluded by Article L. 224-9 of the Code de la route for offences related to alcohol or narcotics. However, the judge may authorise you to drive solely vehicles equipped with an ignition interlock breathalyser (EAD).
Yes. French authorities cannot deduct points from a foreign driving licence that is not registered in France, but they have the power to issue a driving ban on French territory. The préfet or the judge can suspend your right to drive in France, and your physical licence can be confiscated and sent back to the authorities of your home country.
