Speed limits are among the most frequently tested parts of the theory test for driving licence B — and among the sections where the most common mistakes are made. Not because the basic rules are difficult, but because candidates do not know the regional differences, exceptions and the crucial difference between maximum speed and adjusted speed well enough.

In this article you will get a complete and fact-checked overview of all speed limits in Belgium in 2026, including the differences between the regions, all special zones and a systematic approach to speed questions on the test.

Overview: speed limits in Belgium by region (2026)

Speed limits in Belgium are partly federal and partly determined by the regions. That makes it more complex than in most neighbouring countries. Here is the full overview:

Speed limits by road type: the details

1. Within built-up areas

In Flanders and Wallonia, the standard within built-up areas is 50 km/h. In Brussels, the region has introduced a general limit of 30 km/h for the entire city — unless signs allow a higher speed.

Exceptions that exam questions deliberately test:

•        Zone 30: 30 km/h, indicated by a zone sign — applies until the 'end of zone' sign

•        Home zone: maximum 20 km/h — indicated by the F12a sign (blue background with playing children)

•        School zone: 30 km/h when the zone sign is present or the dynamic sign is active

•        Cycle street: you may not overtake cyclists — your speed may never be higher than that of the cyclist in front of you

2. Outside built-up areas

This is where the biggest region-specific source of confusion lies in the theory test for driving licence B:

•        Flanders: 70 km/h on ordinary roads outside built-up areas

•        Wallonia: 90 km/h on ordinary roads outside built-up areas

•        Brussels: 70 km/h outside built-up areas

On roads outside built-up areas where the traffic directions are separated by road markings (but without a physical central reservation), 70 km/h applies in Flanders and Brussels, 90 km/h in Wallonia. Always pay attention to traffic signs — they take precedence over the standard rule.

3. Motorways

On motorways throughout Belgium, a maximum speed of 120 km/h applies to passenger cars. A minimum speed of 70 km/h also applies on motorways and dual carriageways, unless conditions do not allow it.

•        Roadworks: temporary signs lower the limit — these override the standard 120 km/h

•        Dynamic signs: digital signs can temporarily adjust the limit in traffic jams or bad weather

•        Brussels Ring Road (Flemish side): large sections with a maximum of 100 km/h

•        In rain or poor visibility: adjusted speed is mandatory — even if 120 km/h is posted

Maximum speed vs. adjusted speed: the crucial difference

This is the nuance most often tested in speed questions on the theory test for driving licence B. Many candidates do not understand the difference well enough.

Concretely: if it is raining on a road with a 70 km/h limit, the correct speed may be 50 or 60 km/h — even if the sign allows 70. Conditions in exam questions are never mentioned by accident. They are the key to the correct answer.

Systematic approach to speed questions on the theory test

Use this fixed order for every speed question:

Common mistakes in speed questions on the theory test for driving licence B

•        Forgetting Wallonia: candidates apply 70 km/h on Walloon roads — the correct speed is 90 km/h outside built-up areas

•        Forgetting Brussels: within built-up areas in Brussels, 30 km/h applies as standard, not 50 km/h

•        Maximum speed = correct speed: the biggest misconception — conditions determine the adjusted speed

•        Getting the home zone speed wrong: in a home zone, 20 km/h applies — not 'walking pace' or 30 km/h

•        Zone sign vs. standard sign: a zone sign applies until the 'end of zone' sign; a C11 sign applies until the next junction or a new sign

•        Raised features (Flanders 2026): from 1 September 2026, 30 km/h will automatically apply at raised features in Flanders — even without a sign

Frequently asked questions (FAQ)

Conclusion

Speed limits in Belgium are more complex than they seem — because of the regional differences between Flanders, Wallonia and Brussels, the exceptions for special zones and the crucial distinction between maximum speed and adjusted speed. Anyone who knows all these nuances and analyses them systematically will no longer lose points on speed questions.

Remember: the conditions in an exam question are never accidental. They are the key to the correct answer.
