Quick answer

Roundabouts is best studied as a practical safety topic, not as a list of isolated facts. Start with the public rule, then practise how the rule changes your speed, position, observation, or choice of route.

The current public Trafikverket information for category B states that the theory test uses 70 multiple-choice questions, that 65 are scored, that 5 are sample questions, that the time limit is 50 minutes, and that 52 correct scored answers are needed to pass. Because official details can change, this site keeps those values in a configurable file and shows review dates where they matter.

How to study this topic

Use this guide together with category practice. Read a short explanation, answer original questions, and review mistakes while the reasoning is still fresh. If a question feels easy, explain why each wrong answer is wrong before moving on.

Learners who study in English should also learn key Swedish terms they may see in traffic or booking contexts. You do not need to translate every word at once, but you should recognise common concepts such as priority, warning, parking, winter conditions, and impairment.

Common test traps

Many wrong answers come from choosing the legally possible action instead of the safest action. Swedish theory questions often reward early risk recognition: slowing before the hazard becomes obvious, leaving extra margins, and protecting vulnerable road users.

Another common trap is treating one fact as absolute. A posted speed is a maximum, a familiar road can still be slippery, and a sign may be changed by a supplementary plate. When in doubt, look for the answer that combines the rule with defensive judgement.

What to verify officially

Before booking or taking the test, verify current test structure, price, language options, identification rules, and appointment procedures through Trafikverket and Transportstyrelsen. This site is independent and cannot replace official instructions.

Use the source links on this page as a starting point. If a page has changed, report it so the editorial review date can be updated and the study material can be corrected.

Practice checklist

After reading this guide, open a related practice category and answer at least ten questions about roundabouts. For every mistake, write a one-sentence reason for the correct answer before you continue. This prevents fast guessing from feeling like real understanding.

Return to the same topic the next day and use bookmarked questions first. If the explanation now feels obvious, remove the bookmark. If it still feels uncertain, read the related guide section again and check the official source for the current public wording.
