Road regulations
Speed limits
Speed limits in France depend on the type of road and the weather. Unless signs say otherwise, the limits are:
- Motorways (autoroutes): 130 km/h (about 81 mph), dropping to 110 km/h (about 68 mph) in rain.
- Dual carriageways: 110 km/h, dropping to 100 km/h in rain.
- Other roads outside towns: 80 km/h (about 50 mph). Some départements have raised this to 90 km/h on selected roads, which will be clearly signed. In rain, 90 km/h roads drop to 80 km/h.
- Towns and villages: 50 km/h, and many cities, including Paris, now have 30 km/h limits on most streets.
- Fog: when visibility is below 50 metres, the limit is 50 km/h on every road, including motorways.
The lower wet-weather limits apply automatically as soon as it rains, even if the signs don’t change. If you’ve held your licence for less than three years, the lower limits apply to you at all times.
Speeding in France really isn’t worth the consequences. Going 40 km/h or more over the limit can see your licence suspended on the spot. Since 29 December 2025, driving 50 km/h or more over the limit is a criminal offence, punishable by a fine of up to €3,750, up to three months in prison, a criminal record, six points, a licence suspension of up to three years and the confiscation of your vehicle.
Alcohol limit
It’s never a good idea to have an alcoholic drink and then drive. France’s limit is 0.5 grams of alcohol per litre of blood, which is lower than the 0.8 limit in England, Wales and Northern Ireland, so think twice before enjoying a beer or a glass of wine with lunch. If you’ve been driving for less than three years (two if you learned through accompanied driving), the limit drops to 0.2 grams per litre, which in practice means not drinking at all.
Phones and headsets
You can’t hold a phone while driving, even when you’re stopped in traffic, and you can’t use headphones, earbuds or headsets to make calls or listen to music. The fine is €135 and three points. Hands-free systems built into the car are allowed.
Radar detectors
Any device, app or navigation system that detects radars or speed cameras is illegal in France. Remove or disable these features on your phone or satnav to avoid a fine of up to €1,500, the loss of six points and the confiscation of the device. Apps that warn you of general “danger zones” rather than exact camera locations are allowed.
