Speed regulations and limits in Belgium by region

In Belgium, the maximum speed depends on the region and the road type. Within the built-up area, you may drive 50 km/h, in Brussels 30 km/h. Outside the built-up area, this is 70 km/h in Flanders and Brussels, and 90 km/h in Wallonia. On the motorway, the speed limit is 120 km/h everywhere. Traffic signs always take precedence over these standard rules.

Within the built-up area

The standard limit is 50 km/h in Flanders and Wallonia. In the Brussels-Capital Region, it is 30 km/h, unless signs indicate otherwise locally.

Outside the built-up area

If there are no signs, the speed limit on regular roads is: 70 km/h in Flanders and Brussels, 90 km/h in Wallonia.

There is one important exception that lifts the regional boundary: if you are driving outside the built-up area on a road with at least two lanes in your direction, where the lanes are separated by a physical median (guardrail or concrete structure), then you may drive 120 km/h throughout Belgium.

Note: if the lanes are only separated by road markings (dashed lines), without a physical median, then the regional limit (70 or 90) applies, not 120.

Motorway or dual carriageway?

Motorway (sign F5)Maximum 120 km/h, with a minimum speed of 70 km/h when conditions allow.

Dual carriageway (sign F9)No minimum speed. The maximum speed follows the surroundings (within or outside the built-up area).

Always adjust your speed

According to Article 10 of the Highway Code, you must constantly adjust your speed to the weather and the condition of the road. The maximum speed is therefore not always the correct speed. Driving abnormally slowly without a valid reason is also punishable if it causes danger or inconvenience.
