Swedish theory test for category B: how the knowledge test works

The Swedish theory test, officially called the knowledge test, is one of the two Trafikverket tests for a category B driving licence. It checks whether you understand traffic rules, risk awareness, safety, the environment and how to make good decisions in traffic.

The test is not only about remembering signs. To pass, you need to understand why rules exist and how to apply them in realistic situations.

Before you book

Make sure the required steps in your process are in order before test day. For category B, your risk training must be completed and valid before you take the theory test and the driving test. If you are unsure, check with your driving school, Transportstyrelsen or Trafikverket before booking.

You also need valid identification at the test centre. If this is your first knowledge test, Trafikverket normally takes your photo before the test. Plan to arrive early so this does not become stressful.

Test format

For category B, the ordinary knowledge test is computer based. Trafikverket states that the test has 70 questions and lasts 50 minutes. Only 65 questions count toward the result because 5 are trial questions. To pass, you need 52 correct answers.

You receive the result directly after the test. If you pass, the result is valid for 4 months. During that period you must also pass the driving test, otherwise you need to take the knowledge test again.

What the questions cover

The questions can cover several areas: traffic rules, road signs, safety margins, environmental driving, vehicle knowledge, vulnerable road users, alcohol and drugs, fatigue, speed and responsibility.

A common mistake is studying only by repeating app questions. Practice questions are useful, but the real goal is to understand the logic behind the answer. Trafikverket is clear that the exact questions from practice tools are not the same as the official test.

Language and support

The category B knowledge test can be taken in Swedish or in several translated languages. If you need special support, there may be options such as extra time, oral test or interpreter, depending on your situation and approval.

Do not wait until the week of the test to ask about support. If you need an adapted test, check the current rules early and make the request before booking your final date.

How to prepare

Start with the official content areas: signs, rules, risk, environment, vehicle and safety behaviour. Then connect every topic to real driving. Ask yourself: what would I do if visibility is bad, a child is near the road, a cyclist is hidden by parked cars or the road surface changes?

Use practice questions to find weak areas, not as a substitute for understanding. When you get an answer wrong, write down the reason. Was it a rule you did not know, a Swedish word you misunderstood or a risk you underestimated?

Test day tips

Arrive with time to spare, bring valid ID and avoid studying frantically outside the test room. Read each question carefully. Many questions are designed to test judgement, not speed.

If two answers look possible, look for the safest, most rule-consistent option. The Swedish driving system rewards defensive thinking: lower risk, better margins, attention to vulnerable road users and responsibility before convenience.

After the test

If you pass, book or keep your driving test within the validity period. If you fail, use the result as feedback. Do not only book the next available time. First identify why you failed: language, weak rule knowledge, stress, question reading or poor risk understanding.

The theory test becomes much easier when it is not treated as a memory game. Learn the system, practise the language of the questions and connect the rules to how safe drivers actually behave.

Practical quality checklist

This page is most useful when you connect it to real driving practice. For this topic, keep the main focus clear: A practical guide to the Swedish category B theory test: format, pass score, timing, validity, language support and how to prepare without memorising fake questions.

Before you start, name the exact risk you are training today and where it usually appears in Swedish traffic.
During practice, connect the theory rule to observation, speed, road position and communication with other road users.
After practice, write down one situation that felt late or uncertain and decide what earlier clue you should notice next time.
When reviewing practice questions, explain why the safe answer is safe instead of only remembering the correct option.

Mini practice scenario

Choose a normal route near home, a driving school or Trafikverket-style test area. Drive it once slowly with the goal of noticing A practical guide to the Swedish category B theory test: format, pass score, timing, validity, language support and how to prepare without memorising fake questions. Then repeat the same route and ask whether your decisions became earlier, calmer and easier to explain.
