Choose STR and take the right path with your training provider


Choosing an STR-affiliated training provider provides great security for you as a consumer and future road user. STR-affiliated training providers undergo inspections by the Swedish Transport Agency (Transportstyrelsen) and actively work to improve road safety. They take great responsibility to ensure that you, as a student, receive all the support you need during your education.

But it's also good to know that in order to be affiliated with STR, training providers must meet certain additional requirements regarding teaching, finances, insurance, and consumer protection, which benefit you as a student. If, despite everything, you are not satisfied with your driver training, you can always turn to STR's own complaints board for assistance. That provides double security.

How does it work inside Körkortsboken?

3 ways to study theory

You can study the driver's license theory in three ways: Read, Practice, and Quiz. You choose which path you want to take and in what order you do it. It's not mandatory to go through all the material, but the more knowledge you have, the more confident you'll feel when it's time to take the theory test.



Under Read you will find everything you need to know about the driver's licence theory presented in text and images.



Mix your reading with exercises and videos as you like. This makes studying varied, more enjoyable, and enhances understanding.



Answering questions allows you to both learn and test your knowledge. The practice questions are very similar to 'real' test questions, but here you immediately find out if you answered correctly or incorrectly with an explanation.

Features in Körkortsboken


You can take quick tests or more comprehensive tests. Choose to test yourself within a specific subject or in mixed subjects. Take all the time you need or set a time limit. You decide! All correct answers are based on your proficiency level under "Progress".

Once you have reached a proficiency level of 75% in all subjects, you are ready for the final tests. The questions here are unique, and the tests are designed just like Trafikverkets's theory tests.

My driving training

An STR-affiliated training provider assists you in developing a schedule and a structure tailored specifically to you. The plan - which includes both theoretical and practical components - is carefully designed to help you achieve your goal.


You can track your progress and see when you are approaching your goals. Your progress is measured in actual knowledge and not how much of the material you have gone through. It is correct answers to the questions in Quiz and Test that raise your knowledge level from 0 to 100%
