Navigating French traffic laws requires a precise understanding of how speed limits change based on road infrastructure and environmental factors. This guide explains the standard limits for motorways, two-way roads, and built-up areas, while highlighting the critical exceptions that often appear in ETG exam questions. By mastering these regulations, you will improve your hazard perception and prepare effectively for your driving test.

Understanding speed limits is a fundamental pillar of the French Code de la route. For candidates preparing for the Épreuve Théorique Générale (ETG), recognizing not just the base limits, but also the environmental and local exceptions, is essential for both passing the exam and driving safely on French roads. This guide clarifies the official speed regulations for 2026, ensuring you are ready for any question on the theory test.
In France, speed limits are strictly dictated by the type of road and whether there is physical separation between opposing lanes. On standard roads, the limit changes based on the infrastructure, such as the presence of a central divider (terre-plein central).
| Road Type | Speed Limit |
|---|---|
| Built-up Areas (Agglomération) | 50 km/h |
| Two-way roads without a central divider | 80 km/h |
| Dual carriageways with a central divider | 110 km/h |
| Motorways (Autoroute) | 130 km/h |
Local authorities have the power to reduce these limits within their jurisdiction. Always scan for regulatory signs that override standard national limits, as exam questions often feature these specific scenarios to test your attention to signage.
One of the most common pitfalls in the theory exam involves the 80 km/h limit on two-way roads without a central divider. While 80 km/h is the national standard, local authorities are permitted to increase this limit to 90 km/h on certain sections of these roads. You must always prioritize the speed limit displayed by road signs over your general knowledge of the national rules.
The Code de la route emphasizes the importance of adjusting your speed according to visibility and weather conditions. If it is raining, or if other precipitation is falling, the maximum authorized speed limits are automatically reduced to ensure road safety.
If visibility is reduced to less than 50 meters—often due to heavy fog, snow, or torrential rain—the speed limit on all road types is restricted to 50 km/h. Examiners frequently use weather-based scenarios in the ETG to see if you can correctly identify the necessary speed reduction.
Familiarizing yourself with the core terminology used in the official test will help you interpret questions more accurately.
The theory exam rarely asks for simple rote memorization. Instead, you will be presented with a RoadSituationPlaceholder where you must assess the environment in real-time. You might see a dual carriageway that changes into a single road, or an urban area that transitions into a rural zone.
Always look for signs that indicate the end of a zone, such as a zone-end sign, and be prepared to identify when the national default limits resume. If you are unsure, remember that the "safe" answer is almost always the lower, more cautious speed, especially in adverse conditions.
French speed limits are determined by road type and infrastructure, with specific limits for built-up areas, two-way roads, dual carriageways, and motorways. The Code de la route requires drivers to adapt their speed to weather conditions—rain reduces limits on higher-speed roads, while poor visibility below 50 meters restricts all roads to 50 km/h. Local authorities have powers to adjust national limits, making it essential to watch for regulatory signs. The ETG exam tests your ability to recognize these rules in context, so always prioritize displayed signs over memorized defaults, and remember that the safer, lower speed is the correct choice in uncertain conditions.
A short set of high-value points that capture the most important ideas from this article.
Speed limits in France depend on road type: 50 km/h in built-up areas, 80 km/h on two-way roads without central divider, 110 km/h on dual carriageways, and 130 km/h on motorways.
Local authorities can increase the 80 km/h two-way road limit to 90 km/h on certain sections, and can also reduce any national limit within their jurisdiction.
In rainy conditions, motorway limits drop to 110 km/h, dual carriageways to 100 km/h, and other roads remain at 80 km/h.
When visibility falls below 50 meters, the speed limit on all road types is restricted to 50 km/h regardless of other conditions.
Always prioritize speed limit road signs over general knowledge of national rules, as local overrides are common.
Built-up areas are marked by town name signs and default to 50 km/h.
The terre-plein central (physical divider) determines whether a road is 80 km/h or 110 km/h.
Rain reduces motorway limits by 20 km/h and dual carriageway limits by 10 km/h.
Visibility under 50 meters triggers an automatic 50 km/h limit on all roads.
Agglomération means a built-up area; Autoroute is a high-speed motorway with limited access.
Assuming 80 km/h is always the limit on two-way roads without checking for 90 km/h authorized sections.
Forgetting that rain automatically reduces motorway and dual carriageway speed limits.
Ignoring local authority speed limit signs that override national defaults.
Confusing visibility-based speed restrictions with weather-based reductions.
Not recognizing zone-end signs that restore national default limits after a restricted section.

The general speed limit for a two-way road without a central divider is 80 km/h, though local authorities may adjust this to 90 km/h in certain cases.
When it rains or during other forms of precipitation, speed limits are reduced, such as 110 km/h on motorways instead of 130 km/h and 80 km/h on dual carriageways instead of 110 km/h.
The maximum speed limit in built-up areas (agglomération) is 50 km/h unless specifically signed otherwise.
Yes, local authorities responsible for traffic management have the power to reduce speed limits or, in specific instances, increase the limit on certain two-way roads.
