Speed on a moped: your ceiling is your class
⏱️ 2 min read
In a car, the limit depends on the road. On a moped, it depends first on your machine: class A or class B. Here's how the two logics combine — and the trap the exam loves.
✨ Key takeaways
- Class A = 25 km/h max, class B = 45 km/h max, everywhere.
- Lower local limits also apply: 30 zone = 30, residential zone = 20 km/h.
- Golden rule: you ride at the lower of the two figures (your class or the sign).
- Derestricting = riding a motorcycle without a licence, without valid insurance.
A moped is limited by construction: class A cannot exceed 25 km/h, class B cannot exceed 45 km/h. This ceiling follows you everywhere, whatever the limit posted on the road.
Then, local limits lower than your ceiling apply to you just as to any driver: a 30 zone remains a 30 zone, even in class B.
| Location | Class A | Class B |
|---|---|---|
| Residential / home zone | 20 km/h | 20 km/h |
| 30 zone / school surroundings / cycle street | 25 km/h | 30 km/h |
| Built-up area (50 km/h) | 25 km/h | 45 km/h |
| Outside built-up areas (70 or 90 km/h) | 25 km/h | 45 km/h |
And derestriction? A moped tampered with to exceed its construction speed is no longer a moped: legally, you are riding a motorcycle without the proper licence, your insurance can refuse to pay out after an accident, and the vehicle can be seized. In the exam as in life: derestricting = losing everything.
Outside built-up areas in Wallonia (90 km/h limit), you are riding a class B moped. Your max speed?
