Driving in France as a foreigner: the rules that actually catch people out
France drives on the right, signs in kilometres, and most of its road code matches what you already know. What catches foreign drivers isn't the obvious; it's four specifics: a priority rule that predates roundabouts, an alcohol limit lower than the UK's and most US states', camera enforcement that mails fines across borders, and equipment the law expects to find inside your car. Master those and French driving is genuinely pleasant. Here's each one, plus the smaller rules worth knowing.
Priorité à droite: the rule nobody warns you about
By default, traffic entering from your right has priority at unmarked junctions, even from a small side street onto what feels like the main road. In practice, most significant roads override this with priority signage: a yellow diamond means you have priority until a crossed-out diamond ends it, and stop or give-way markings control the rest. But in villages, old town centres and some Paris streets, the default lives on, and a local pulling out from the right without a glance is not being reckless, they're being legal. When you see no signs and no markings at a junction, assume the right has it.
Roundabouts mostly work the modern way, signed "Cédez le passage" so traffic on the roundabout has priority. The infamous exception is the Arc de Triomphe's Place de l'Étoile, where entering traffic has priority and insurance claims are settled 50/50 by tradition. Treat it as a spectator sport, not a route.
Alcohol, phones and the enforcement web
The blood alcohol limit is 0.5 g/L, roughly one small drink, and 0.2 g/L for licences held under three years, which is effectively zero. Enforcement is real and the fines climb quickly toward licence suspension. The two-glasses-of-wine lunch that feels normal on holiday is over the limit; someone drives dry or you linger over coffee.
Handheld phone use costs €135, and holding a phone while driving includes at red lights. France's fixed and mobile speed cameras are dense, unmarked in the mobile case, and connected: fines for foreign-registered and rental cars follow you home through the rental agency, with an admin fee added. The camera tolerance is small, around 5 percent, so drive to the number on the sign rather than the number plus the cushion you're used to. The limits themselves change with weather and road type, and are worth two minutes on our French speed limits guide before your first autoroute.
What must be in the car
French law requires a high-visibility vest reachable from the driver's seat and a warning triangle; any rental includes both, but confirm where they live before you need them at night on a hard shoulder. Children under 10 ride in the back in an appropriate seat or booster. Headphones and earbuds while driving are banned outright. Radar detectors are illegal, including detector features in navigation apps, though speed-limit display and fixed-camera "danger zones" in apps like Waze remain legal. Winter equipment rules apply in mountain areas from November to March under the Loi Montagne, where snow tyres or chains on board are mandatory; if the Alps or Pyrenees are in your plan, say so when booking so the car matches the law.
The full official rulebook lives at securite-routiere.gouv.fr, France's road safety authority, which is the reference when a rule matters enough to verify.
The autoroute and beyond
Autoroutes are excellent, tolled, and covered separately in our French toll roads guide. Two habits matter there: keep right except to overtake, enforced socially by flashing headlights if not by police, and never stop on the hard shoulder except in emergency, using the orange phones rather than your mobile so responders locate you. Off the autoroute, watch for the 30 km/h zones spreading through towns, Paris included, and for stop signs meaning a full stop, wheels still, which French police enforce literally. City driving also brings low-emission zones into play, a paperwork rule rather than a driving one, explained in our Crit'Air and ZFE guide.
None of this should put you off. Outside the biggest cities, French roads are among Europe's best and emptiest, and a rental with the rules understood is the way to see the country. If you're visiting and want the car sorted to match, our tourist car rental in Paris includes the equipment the law expects and a team that answers rule questions before they become fine questions.
FAQ — Common Questions Answered.
Is it hard for foreigners to drive in France?
Outside Paris, no. Roads are well engineered, signage is consistent, and drivers are more disciplined than the stereotype. The genuine adjustments are priorité à droite in towns, the low alcohol limit, and camera density. Give yourself one easy first day, ideally not starting in central Paris, and the rest follows. British drivers add the left-to-right switch, which roundabouts and first turns of the day test most.
Do French traffic fines reach foreign drivers?
Reliably. EU information-sharing sends camera fines to most European home addresses, and rental drivers everywhere are identified through the agency, which passes the fine plus an administration fee to your card. Pay promptly if it's fair: French fines discount for fast payment and escalate steeply when ignored. If you believe a fine is wrong, the notice includes a contest procedure, but the discount clock runs while you decide.
What do I legally need to carry in the car in France?
A driving licence, the vehicle's registration and insurance papers (in the rental's document folder), a high-visibility vest within reach, and a warning triangle. Non-EU licence holders should add an International Driving Permit or French translation. The once-required personal breathalyser is no longer enforced with a fine. For mountain regions in winter, snow equipment joins the list under the Loi Montagne. A rental from any serious agency carries the car-side items as standard.
