The VKU comprises eight lessons of 45 minutes each, usually spread over four evenings of two lessons. Unlike the basic theory, it is not about factual knowledge but about traffic sense: how do I recognise hazards in time? How does the looking-and-observation process work? How do I behave considerately towards pedestrians, cyclists and others? Topics such as reaction time, stopping distance, distraction and alcohol are also covered.
The VKU is mandatory for all first-time applicants in categories B (car) and A (motorcycle) and must be completed before the practical test – without a VKU certificate you will not be admitted to the practical test. It makes sense to attend it once you already have the learner's permit and some driving practice, because the content can then be better linked to your own experience.
The course must be attended in full; there is no exam, but attendance is confirmed. The VKU certificate has limited validity (usually 24 months) – anyone who does not take the practical test afterwards may have to repeat the course.
As a price guide in Switzerland, expect roughly CHF 200 to 260 for the four evenings (without guarantee, depending on driving school and region). This makes the VKU one of the predictable fixed costs of driver training. Book early, as popular slots (evenings, weekends) sell out quickly.
Important: the VKU is often confused with the basic theory. Rule of thumb: basic theory = knowledge test at the start (for the learner's permit), VKU = mandatory classroom course towards the end (for the practical test).
