The 12 hardest questions in the Belgian theory test
Home › The 12 hardest questions in the Belgian theory test
Some questions in the Belgian theory test fail candidates who actually know the highway code well. They are not difficult questions: they are questions where intuition gives the wrong answer. Here are the twelve traps that come up most often, with the exact rule so you never fall for them again.
Key points
Traps are predictable
They always involve the same exceptions: priority, stopping, lights and distances.
One short rule each
Every trap is defused with one sentence to remember, not a whole chapter.
Practise under real conditions
With fifteen seconds per question, only timed practice reveals your real weak spots.
Traps 1 to 4: priority and junctions
- 1. Flashing amber gives no priority: follow the signs present or, if there are none, priority to the right.
- 2. Dirt tracks: a driver coming out of a dirt track, a path or a private property must give way, even when coming from the right.
- 3. Manoeuvres: anyone pulling out of a parking space, making a U-turn or reversing gives way to all other road users.
- 4. A green light does not allow you to enter a junction if it is blocked and you could get stuck in it.
Traps 5 to 8: stopping, parking and overtaking
- 5. Stopping or parking? Staying behind the wheel with the engine running does not turn parking into stopping: only the purpose counts.
- 6. Bus stops: no parking within 15 metres either side of the sign, but stopping is allowed.
- 7. Overtaking on the right is allowed when the vehicle ahead has moved left to turn left.
- 8. Trams are normally overtaken on the right, if there is enough room.
Traps 9 to 12: speed, lights and scoring
- 9. Brussels applies 30 km/h by default in built-up areas, except on signed roads at 50 or 70 km/h.
- 10. The rear fog light may only be used when visibility falls below 100 metres because of fog, snow or heavy rain.
- 11. Braking distance quadruples when speed doubles; it does not simply double.
- 12. Not answering counts as a mistake, with that question's weight: always pick an answer.
Each topic has its own page: priority rules, stopping and parking, overtaking, car lights.
Why people get it wrong, and how to avoid it
Traps work because the exam shows a photo and gives you about fifteen seconds. Under time pressure, you answer with your habits as a passenger or cyclist, not with the rule. The only real fix is to meet these situations several times in practice, in the same format and with the same timer.
On PermisBelges, every mistake is recorded and comes back in your revision sets until you master it. That is how a trap becomes a reflex.
Practise this topic with real exam questions
Reading a rule is not enough: in the Belgian theory exam every question is asked on a photo of a real traffic situation, with answers that look deliberately alike. On PermisBelges, every topic of the highway code is practised with questions in the GOCA exam format, each one corrected and explained.
