Exam format and simulation

Kat. B: 50 questions · 45 minutes · passed with at most 15 error points

Every question has three answers, of which one or two are correct. Each wrongly ticked answer and each missing correct answer counts as one error point.

According to the road traffic offices, the basic theory exam for passenger cars (cat. B) is the same exam as for motorcycles (cat. A and A1). Changes have been announced for the period from 1 January 2027: a new competence catalogue applies, the traffic theory course (VKU) is to be attended before the basic theory exam, and the exam is to have 55 instead of 50 questions; the time and error limit for it had not yet been published in October 2026. The simulation reflects the format valid until 31 December 2026.

Information as of October 2026. Exam rules can change; the responsible authority (the road traffic office of your canton) is decisive.

What it is about

The basic theory test comes before the learner's licence for passenger cars (category B). The course covers the way to the driving licence, signs and markings, right of way, speed and stopping distance, overtaking, motorway, tunnel and level crossing, as well as vehicle technology, load and trailers, occupants and child restraints, stopping and parking, hazard perception, fitness to drive, accidents and breakdowns, lights and winter, eco-friendly driving and assistance systems. As in the exam, every question has three answers, one or two of which are correct. In the pictures, your vehicle is the red car.
