Swiss Category C Theory (Truck)

It is a computer-based multiple-choice test taken at your cantonal road traffic office, drawn from the official catalogue published in German, French and Italian. You answer at a terminal, usually with the option to review and change answers before submitting. Ask your canton about the exact procedure, identification requirements and language choice when you book.

The federal authority and the cantonal offices publish the current question count, time limit and pass mark. These figures are set officially and can change, so check the official source for your canton before your test date. Do not rely on numbers quoted in forums or older study apps.

The questions are not designed to trick you, but the catalogue is broad and includes vehicle technology, tachograph rules and dangerous goods basics that car drivers never meet. Candidates who only memorise road signs usually struggle. Working systematically through the official catalogue and reviewing your errors is what separates a comfortable pass from a borderline one.

Retakes are possible, but the conditions, waiting periods and fees are set by the canton and the federal rules. Confirm the retake policy with your road traffic office when you register, and budget time for a second attempt rather than assuming you can rebook immediately.

The official catalogue exists in German, French and Italian, and the test is normally offered in those languages. Some cantons may offer additional options, so ask when booking. Study in the language you will be tested in, because technical terms such as load securing or rest periods are easier to recognise than to translate under time pressure.

Start with traffic law, signs and markings, because they underpin many other questions and are familiar ground. Then move to vehicle knowledge, weights and loading, and driving physics. Leave working time and tachograph rules and dangerous goods basics for later, since they are more specialised and benefit from focused sessions rather than casual reading.

Common weak spots are tachograph and working-time rules, load securing and weight limits, and braking or centrifugal-force questions where the answer depends on mass and speed. Another frequent problem is reading a question too quickly and missing a qualifier such as 'in this situation' or 'is not permitted'.

No. The theory test is a prerequisite for the Category C learner permit and for the practical driving test. You still need the learner permit, practical training and a passed practical test, plus any required medical or fitness-to-drive checks, before the licence is issued.
