Classic exam traps: theory and practical

Part 1 — Theory exam traps

In the theory exam, the trap is almost never the rule itself: it's the wording of the question. Read each question twice, all the way through, before looking at the answers.

• "May" is not "must": "the driver may give way" and "must give way" are two different answers. Spot the exact verb.
• Hidden negations: "which statement is NOT correct?" — half of all careless mistakes come from this.
• "Always" and "never": an absolute answer is often wrong… except when the rule really is absolute (the tram always has priority, stopping in a tunnel is always forbidden).
• Near-identical numbers: 0.5 vs 0.2 ‰ (novice/professional driver), 30 vs 50 km/h in built-up areas depending on the region, 1 m vs 1.5 m when overtaking a cyclist. The exam loves swapping these pairs.
• The image matters as much as the text: a mirror, an indicator that's on or a road marking in the photo often changes the correct answer.

B19 — YOU give way at the narrow passing point

B21 — YOU have priority at the narrow passing point

💡 Red circle = you wait (B19). Blue square = you go (B21). The RED arrow always marks the one who gives way.

Part 2 — Practical exam traps

Roughly one candidate in two fails their first attempt, and almost always for the same reasons. Here are the traps that the exam centres (GOCA) and Belgian driving schools cite most — on both the French-speaking and Dutch-speaking sides.

1. Your observation must be SEEN. Checking your mirrors is not enough: the examiner must see your head movements. Invisible "kijkgedrag" is the number 1 cause of failure cited by the centres.
2. The blind spot before EVERY manoeuvre: changing lane, turning, pulling away, leaving a parking space — turn your head clearly over your shoulder.
3. Priority from the right in small streets. THE cause of failure on the road: slow down at every unsigned junction in a residential area and scan right-left-right.
4. Driving too slowly also makes you fail. The centres' official document says it: without "sufficient participation in traffic", the examiner cannot assess you — and can fail you. 30 zone = 30, but a clear 50 road = ~50.
5. A pedestrian who has stepped onto the crossing = mandatory stop. Failing to give way to a pedestrian on a crossing is an instant fail, and the lateral distance (1 m / 1.5 m) from cyclists is watched.
6. Indicate BEFORE braking, not while braking. Too late = a recurring fault flagged by every driving school.
7. A STOP means wheels fully stationary. A "rolling stop" is an instant fail. Complete stop, look left-right-left, then move off.
8. Hesitation costs you. Stopping when you have priority or not daring to merge "creates confusion" — it is penalised as a fault.
9. Safe following distance: 2 seconds, doubled in bad weather — and keep a margin from parked cars.
10. Stalling is NOT a fault. The centres say so officially: stay calm, restart cleanly. Panicking, on the other hand, shows.

Manoeuvres and independent driving, region by region

The administrative trap: failed before you even start

• ORIGINAL documents only — no photocopies, and a passport is refused: identity card, theory pass certificate (< 3 years old), valid provisional driving licence, TPR certificate where applicable.
• Vehicle in order: visible L sign, a second interior mirror for the accompanying driver (the sun-visor mirror doesn't count), insurance, registration and roadworthiness test.
• Cancellation: at least 2 full working days in advance (Saturday not included), otherwise a surcharge at the next appointment.
• The pre-drive checks must be known by heart: tyre wear and pressure, lights, horn, demisting, warning lights off — and when getting out: left mirror before opening the door, walk round the vehicle facing the traffic.
