Speed limits in France
Home › Speed limits in France
Speed limits vary by road type and conditions. Here are the general rules in France - a key exam topic. Local signage always overrides these defaults.
Default speeds
In built-up areas
50 km/h as a rule. Zone 30 and school areas require 30 km/h; some towns apply 30 km/h across the whole city.
Outside built-up areas
80 km/h on two-way roads without a central separator, 110 km/h on dual carriageways. Subject to signage.
On the motorway
130 km/h in dry weather (110 km/h in rain), with a minimum of 80 km/h in the left lane.
Why the rural road is the one to watch
In built-up areas, on motorways and in zones, the limit is the same everywhere in France. On ordinary rural roads it is not quite: the national default is 80 km/h, but since 2019 each department may raise it to 90 km/h on stretches it judges safe.
The practical consequence is that the same kind of two-lane road can carry 80 in one department and 90 in the next. Habit is a bad guide, and the sign is the only reliable one. Everything else on this page is uniform nationwide.
One more variation is not geographic but meteorological: on a motorway the 130 km/h limit drops to 110 km/h in the rain, and dual carriageways drop from 110 to 100. It is a rule the exam tests directly.
The default limits
These apply when no sign says otherwise. Exam questions typically show a situation with no sign and ask what is permitted.
| Where | Limit | Note |
|---|---|---|
| Built-up area | 50 km/h | Many town centres now default to 30 km/h by local decision |
| 30 zone | 30 km/h | The whole zone, junctions included |
| Zone de rencontre | 20 km/h | Pedestrians may use the full width and have priority |
| School zone | 30 km/h | Usually a permanent zone sign |
| Rural road | 80 or 90 km/h | 80 by default; a department may raise it to 90 |
| Dual carriageway | 110 km/h | 100 km/h in the rain |
| Motorway | 130 km/h | 110 km/h in the rain; minimum 80 in the left lane |
A sign always overrides the default. The default only applies where there is no sign - and that is precisely the case the exam tests.
Zones do not end at the corner
An ordinary speed sign stops applying at the next junction. A zone sign - the one marked "zone" - applies to the entire area until its matching end sign, junctions included.
This catches people out constantly, both in the exam and on the road: a 30 zone does not lapse at the first side street you cross. It runs until you pass the sign that ends it.
Why ten extra km/h is more than ten per cent
Braking distance does not rise in proportion to speed but with its square. Going from 50 to 60 km/h is 20 % faster and close to 45 % more braking distance - before reaction time is counted at all.
Reaction distance adds roughly one metre per km/h for each second you take to react. At 90 km/h that is about 25 metres covered before your foot even reaches the pedal. On a wet surface, expect roughly double the braking distance - which is exactly why the motorway limit itself drops in the rain.
- Reaction distance ≈ your speed in km/h, in metres, per second of reaction.
- Braking distance grows with the square of speed.
- Wet road: budget roughly double the braking distance.
- The two-second rule replaces all of this arithmetic while driving.
Speeding penalties
A speeding offence in France costs a fine and licence points, deducted from a capital of twelve (six during the probationary period). A small excess is a fixed-penalty fine with one point; the amount and the points rise with the excess.
Above 40 km/h over the limit, the licence can be suspended on the spot, and a large excess brings a court summons. Amounts and thresholds are revised periodically, so check the official source for the figure applying today rather than relying on a number found online.
The limits you need to know
- 50 — km/h in built-up areas
- 130 — km/h on motorways
- 80–90 — km/h on rural roads
- 20 — km/h in a zone de rencontre
Frequently asked questions
What is the speed outside built-up areas in France?
On two-way roads without a central separator the limit is 80 km/h since 2018; on dual carriageways it is 110 km/h, unless a sign states otherwise.
What is the speed limit on rural roads in France?
80 km/h by default, but a department may raise it to 90 km/h on roads it judges safe. A sign always takes precedence over the default.
What is the motorway speed limit in France?
130 km/h for passenger cars in dry weather, dropping to 110 km/h in the rain, with a minimum of 80 km/h in the left lane in normal conditions. Signs can lower the limit locally.
Does a 30 zone apply at junctions inside the zone?
Yes. A zone sign covers the whole area up to its end sign, junctions included. An ordinary speed sign, by contrast, stops at the next junction.
Is there a tolerance on speed cameras?
A technical margin is applied before the recorded speed - 5 km/h below 100 km/h, and 5 % above. Do not treat it as a permitted margin: it covers measurement uncertainty, not a right to exceed the limit.
What is the speed limit in a zone de rencontre?
20 km/h. Pedestrians may use the full width of the road and have priority over vehicles.
