French Driving Rules Visitors Get Wrong on a Road Trip
The first time a small white van pulled out in front of me from a farm lane in the Gers, I braked hard and said some unkind things. The driver had done nothing wrong.

The first time a small white van pulled out in front of me from a farm lane in the Gers, I braked hard and said some unkind things. The driver had done nothing wrong. There was no stop line and no sign, so under French driving rules the van, coming from my right, had priority. I was the one breaking the law, on a quiet road at 70 km/h, with a guidebook on the passenger seat.
Most visitors arrive knowing to keep right and not much else. The rules that catch people out on a road trip through rural France are rarely the obvious ones. They are the small local habits that French drivers learned at sixteen and nobody thinks to explain to you.
Priority to the Right Still Rules Many Village Junctions
Priorite a droite is the rule that surprises everyone. At a junction with no sign, no road markings and no traffic light, a vehicle joining from your right has the right of way, even if it is coming out of a tiny side street and you are on what looks like the main road through the village.
Two signs tell you where you stand:
- A yellow diamond with a white border means you are on a priority road and the rule does not apply to you.
- The same diamond with a black diagonal bar means your priority ends here. Expect cars from the right.
- A red bordered triangle with a black cross means the next junction is priorite a droite.
In practice, slow down through villages and glance right at every opening.
Speed Limits Change Without a Single Number on a Sign
The white sign with a red border and the name of a town is a speed limit sign. It means 50 km/h from that point, whether or not a number appears. The same name with a red line through it, at the far end, ends the limit. Many towns now post 30 km/h through the centre as well.
| Road type | Dry | Rain |
|---|---|---|
| Autoroute | 130 km/h | 110 km/h |
| Dual carriageway | 110 km/h | 100 km/h |
| Two way rural road | 80 km/h, or 90 where signed | 80 km/h |
| Built up area | 50 km/h | 50 km/h |
The rural limit is the tricky one. It dropped to 80 in 2018, and since then many departments have raised some roads back to 90. The same D road can switch between the two as you cross a department line, so watch the signs rather than trusting memory or an app.
Free Flow Tolls Catch Out Drivers Who Never See a Booth
Most autoroutes still have peage plazas. Choose lanes showing a green arrow or a card symbol, and avoid the orange lanes marked with a "t", which are for electronic tags only. Contactless cards work in most lanes, though some foreign cards are refused at automated booths, so keep about 20 euros in coins and notes for those moments.
The newer catch is the free flow motorway. The A79 across the Allier and parts of the A13 and A14 in Normandy have no booths at all. Cameras read your plate, and you are expected to pay online within 72 hours. Rental cars and foreign plates get the fine letter weeks later, often with an admin fee added by the rental company. If your route crosses Normandy, put a reminder on your phone the moment you leave the motorway.
The Kit You Must Carry in the Car
French police can and do check. Before you set off, make sure the car holds:
- A reflective high visibility vest for the driver, kept inside the cabin and not in the boot, because you must put it on before stepping out.
- A warning triangle.
- Your licence, insurance documents and the vehicle registration papers, originals rather than photos.
- Headlamp beam adjusters if you drive a right hand drive car.
The breathalyser kit is a source of confusion. Carrying one is still mentioned in the rules, but the fine for not having it was dropped years ago. Buy a pair for two euros if you like the reassurance; nobody will fine you without them. The alcohol limit itself is 0.5 grams per litre of blood, lower than in the UK, and 0.2 for newly qualified drivers.
Crit'Air Stickers for City Edges You Did Not Plan to Visit
Paris, Lyon, Strasbourg, Grenoble, Montpellier and several other cities run low emission zones that require a Crit'Air sticker on the windscreen, foreign cars included. You might think a rural road trip avoids them. Then your route to a Drome valley inn sends you round the Lyon ring road, or a rainy day pushes you into Strasbourg.
The sticker costs under five euros on the official government site and arrives by post, so order it two or three weeks before you leave. Lookalike sites charge 30 euros or more for the same thing. Rental cars registered in France should already have one; check the windscreen when you collect it.
Why "Stay Off the Autoroute Entirely" Is Poor Advice
Slow travel writing loves the idea of never touching a motorway. It sounds right, and for the last 80 kilometres to an inn it usually is. As a rule for the whole trip it costs you days.
Paris to Beaune is about three and a half hours on the A6. On departmental roads, through towns now limited to 30 km/h, it can take seven or more, mostly spent behind tractors and at roundabouts in places you will not remember. Use the motorway for the dull transit legs and spend the saved time where it counts: on the small roads you actually came for, like the vineyard lanes on a slow road trip through Burgundy.
Phones, Cameras and the Habits That Earn Fines
Holding a phone while driving is banned, and so is wearing headphones or a single earpiece, even for hands free calls. Use the car speaker. Police also fine drivers using a phone while stopped at the roadside with the engine running.
Speed camera detectors are illegal. Navigation apps get around this by warning of "danger zones" instead of exact camera spots, which is legal. Unmarked camera cars now patrol many departments, so the honest approach of just driving at the limit is the cheaper one.
One more rural habit: on long empty stretches, fuel stations are fewer than you expect, and many close on Sunday afternoons. Plan stops using the tips on finding fuel on rural back roads.
Frequently Asked Questions
Do I need an international driving permit in France?
Drivers with a photocard licence from the UK, EU, US, Canada or Australia generally do not need one for a short visit. Rental firms occasionally ask for one with older paper licences, so check with yours before you travel.
Do roundabouts in France use priority to the right?
Almost all modern roundabouts carry a sign saying "Vous n'avez pas la priorite", which means you give way to cars already on the roundabout. A few older ones, like the circle around the Arc de Triomphe, still give priority to cars entering from the right.
What happens if I get a speeding ticket in a rental car?
The fine notice goes to the rental company, which passes your details to the French authorities and usually charges you an admin fee of 30 to 50 euros. The fine then arrives at your home address, sometimes months later.
What to Do Before You Turn the Key
Order the Crit'Air sticker three weeks ahead, put the vest in the door pocket, and note any free flow tolls on your route. Then drive through villages as if every side lane hides a white van coming from the right, because sooner or later one will. More route planning ideas sit in our road trips section.
