Lesson 03
Speed & safe distance
Essential rules, explained step by step.
Educational difficulty is separate from the legal penalty. These are original practice questions, not official examination items.
Residential and meeting zones
In a signed residential or meeting zone, the maximum is 20 km/h. Pedestrians may use the full width; drivers must not endanger or hinder them and must stop when needed. This is a different regime from zone 30.
Regulatory source ↗
In a signed 30 km/h zone, 30 km/h is the maximum, not a target.
Increase your following distance in rain.
Your stopping distance includes reaction distance and braking distance.
A temporary lower speed limit must be respected at roadworks.
For an ordinary passenger car, the default built-up-area limit is 50 km/h in Flanders and Wallonia, but 30 km/h in Brussels. Signs can impose a different limit.
Outside built-up areas, on an ordinary two-way road with no different limit sign, a passenger car is limited to 70 km/h in Flanders and 90 km/h in Wallonia.
On a motorway, an ordinary passenger car is generally limited to 120 km/h unless a lower limit applies. Always adapt speed to conditions.
