Speed-limit questions become easier when you stop memorising one national list. First identify the road and region, then check whether a sign or special zone replaces the default rule.
Use a four-step decision order
For every speed question, identify the road type, the region, any zone and the most recent applicable sign. That order prevents a memorised default from overriding what is actually shown on the road.
- Read the sign
- Identify a special zone
- Identify the region
- Apply the remaining default
The regional differences worth learning
Outside built-up areas, the commonly tested default is 70 km/h in Flanders and Brussels and 90 km/h in Wallonia, subject to signs and road layout. In built-up areas, Brussels generally uses 30 km/h while Flanders and Wallonia generally use 50 km/h unless indicated otherwise.
Residential zones are limited to 20 km/h and Zone 30 remains 30 km/h in every region. Always follow a lower posted limit.
Why signs still decide the real answer
Defaults fill the gap only when no more specific rule applies. Roadworks, variable motorway signals, school environments and local signs can all impose another limit.
The safest exam habit is to describe the evidence you see before choosing a number: sign, zone, road type, region.
Frequently asked questions
What is the general Belgian motorway speed limit?
For a car, the general maximum is 120 km/h unless a sign sets a lower limit.
Is the built-up-area limit the same across Belgium?
No. Brussels generally uses 30 km/h, while Flanders and Wallonia generally use 50 km/h, subject to signs and special zones.
