The category B theory test is the first step in your life as a driver. Format, registration, content, study method: this complete guide tells you everything you need to know to approach the test with confidence — with no surprises on the big day.
1. The exact format of the test
The Belgian category B theory test is taken on a screen at an approved test centre. Here is what to expect:
- 50 questions presented as real-life situations: an image (sometimes a short video clip), a question and answer options
- Pass mark: at least 41/50
- “Serious fault” questions: some questions about serious offences (speeding, alcohol, failing to respect a STOP sign…) carry a heavier weighting — one wrong answer can cost you several points
- Duration: allow 30 to 45 minutes, more than enough if you are prepared
- Equipment: touch screen, with headphones if you want to hear the questions
- Languages: French, Dutch, German; English is available at a higher fee
2. Registration: procedure and budget
You register directly with an approved test centre: GOCA (Flanders), SBAT, AUTO-SECURITÉ or AIBV (Brussels and Wallonia). Most offer online booking.
- Document to bring: your valid identity card — without it, no test
- Fee: around €17 in French/Dutch, more for another language or with an interpreter
- Waiting times: from a few days to a few weeks depending on the centre — book early during busy periods (summer, start of the school year)
- Orientation: some centres offer a visit or information sessions; ask about them if stress is a factor for you
Good to know: if you fail, you can retake the test freely. But after two failures, you will have to complete 12 hours of theory lessons at an approved driving school before trying again. It is therefore best to arrive well prepared.
3. What the test really assesses
Contrary to popular belief, the test does not check rote memorisation but your understanding of road situations. The questions cover:
- Road signs and markings (signs, road markings, traffic lights, police officers’ signals) — about a third of the test
- Priority rules and behaviour at intersections — the most heavily penalised topic
- Speed, safety distances and reaction time
- Position on the road, overtaking and passing oncoming traffic
- Parking, stopping and vehicle lighting
- Vulnerable road users: pedestrians, cyclists, motorcyclists
- Alcohol, drugs, fatigue and the phone while driving — high-weighting topics
- Eco-driving, the vehicle and its documents, first aid
4. The study method that works
Our approach, built on spaced repetition and training in real conditions:
- Learn: go through the 15 course modules in order, 30 minutes a day. Understanding the logic of a rule beats memorising it
- Test: take the mock exams in the official format — 50 questions, same traps, same weighting
- Correct: analyse every mistake using the detailed explanations. A mistake understood is a mistake that will not happen again
- Validate: only sit the test once you score 45/50 on three consecutive mock exams
5. The 7 classic traps on test day
- Answering too quickly without looking at the whole image (a sign in the background changes everything)
- Forgetting that signage overrides general rules (a solid white line forbids overtaking even if the lane is clear)
- Confusing a prohibition sign (round, red border) with a mandatory sign (round, blue background)
- Overlooking the tram: it always has priority, from the right and from the left
- Underestimating questions about reaction time (about 1 second, longer with fatigue or alcohol)
- Believing that right-hand priority has exceptions linked to the size of the road: no, without signage it applies everywhere
- Leaving questions unanswered: answer everything, there are no negative points for an attempt
6. After passing: the provisional licence
Passed? You receive a certificate that lets you apply for your provisional licence at your local council, then start accompanied driving or practical lessons. We cover this step in detail in our article on the provisional licence.
