The Swedish theory test, called teoriprov or kunskapsprov, is the first of the two Trafikverket tests for a category B licence. You must pass it before you can take the driving test (körprov). It checks whether you have the knowledge needed to drive safely and in an environmentally aware way, not whether you can recall individual questions.

What you need before test day

You cannot even book the test without a valid learner's permit (körkortstillstånd) from Transportstyrelsen. Trafikverket also requires that you have completed both parts of the risk training (Risk 1 and Risk 2) and that the training is still valid when you arrive. The risk courses are compulsory before the theory test, not just before the driving test.

On the day you need a valid, accepted ID document. You are photographed before the test, so Trafikverket asks you to arrive at least 30 minutes early. If you are under 18 when you book, the test fee must be paid no later than 25 hours before the start, or the booking is cancelled automatically.

Test format: questions, time and pass mark

The category B theory test is taken on a computer with a touch screen at a Trafikverket test centre.

  • 70 multiple-choice questions, each with one correct answer.
  • 50 minutes of test time, which starts only when you press start after the introduction film.
  • 5 questions are trial questions and do not count, so the maximum score is 65 points.
  • You need 52 points or more to pass.

Headphones let you listen to the questions in Swedish, and a calculator is available at your seat. You may raise your hand and ask for help with a word or a synonym. Your phone must be completely switched off.

You see the result on screen straight away, and it also appears in Trafikverket's booking service. If you fail, you are told which subject areas were weak, but you will not see which questions you answered wrong because the questions are reused in other tests.

The five subject areas

Trafikverket groups the content into five areas:

  1. Vehicle knowledge and manoeuvring: how the car works, how road conditions affect it, and the risks of faults.
  2. Environment: how transport choices affect the environment and how to drive economically.
  3. Traffic safety: judgement when interacting with others, adapting speed and position, and how road and weather conditions affect behaviour.
  4. Traffic rules: signs, road markings, speed, meeting and overtaking, load, passengers and duties towards other road users.
  5. Personal conditions: peer pressure, impulsive decisions and the willingness to follow rules.

Many learners focus only on signs and rules. Traffic safety and personal conditions questions often decide whether you reach 52.

Languages and support

When you book the category B test you choose the language. Besides Swedish, the test is translated into 15 languages: Albanian, Arabic, BKS (Bosnian, Croatian, Serbian), English, Finnish, French, Persian, Russian, Somali, Sorani, Spanish, Thai, Tigrinya, Turkish and German. You can switch to Swedish during the test if you want to compare wording.

If you cannot read and understand Swedish or a translated version, you can apply for a test with an interpreter. The test is then done in a separate room, the test administrator reads the questions in Swedish and the interpreter translates. For category B the test time with an interpreter is 100 minutes. If you have reading difficulties, dyslexia, ADHD, autism, a language disorder or another reason to need support, you can apply for extended time, an oral test or a test with an interpreter. Apply early, well before the date you want.

How long a passed theory test is valid

This rule changed in 2026. A passed theory test for category B taken before 19 August 2026 is valid for four months. A test passed on or after 19 August 2026 is valid for one year. Within that period you must pass the driving test, otherwise you have to take the theory test again.

If you have special reasons, such as an illness that stopped you from taking a retest, you can apply to Transportstyrelsen for an extended validity period. The application must arrive before your pass expires, and a non-refundable fee applies.

Trafikverket's own advice is to book the theory test and the driving test at the same time, a few weeks apart. That way you have time to retake the theory test before the driving test if needed.

Typical theory test traps

  • Memorising question banks. Trafikverket states that practice questions you find online or get from a school are not the questions on the test. Learn the reason behind each answer.
  • Missing a small word. Words like "not", "first" or "most important" change the correct option.
  • Ignoring trial questions. You cannot tell which 5 do not count, so treat every question as real.
  • Underestimating time. 50 minutes for 70 questions is enough, but not if you get stuck. Skip and return.
  • Choosing the convenient answer. When two options look possible, the one with lower risk and larger margins is usually correct.
  • Turning up without valid risk training or ID. You will not be allowed to take the test, and the fee is still charged.

If you fail

You can only take one test per day for the same licence category, so a retest the same day is not possible. Use the area feedback from the result to plan your study, then rebook. Remember that a failed theory test also affects your driving test date if both are booked.

FAQ

How many questions can you get wrong on the Swedish theory test?

Of the 65 questions that count, you need 52 correct. That means you can get up to 13 of the counted questions wrong and still pass. Because you do not know which 5 questions are trial questions, aim well above the limit in practice.

Can I take the Swedish theory test in English?

Yes. English is one of 15 translated languages for the category B test, and you choose the language when you book. You can also listen to the questions in Swedish during the test.

How long is the theory test valid before the driving test?

For tests passed on or after 19 August 2026, the result is valid for one year. Tests passed before that date are valid for four months. You must pass the driving test within the validity period.

Practise in your own language

Körkort Hero lets you practise category B theory questions in 16 languages, with explanations that show why an answer is correct and which subject area it belongs to. Use it to find your weak areas before test day, then confirm current rules with Trafikverket and Transportstyrelsen.
