ExploreAbout this exam
The Czech group D driving licence (řidičské oprávnění skupiny D) authorises a driver to drive motor vehicles designed to carry more than eight passengers in addition to the driver - in practice buses and large minibuses used for passenger transport. Candidates usually seek it to work as a bus driver in public transport, long-distance coach services, or for a transport operator, and it is also the entry point for further professional qualifications such as the driver CPC (profesní způsobilost). The theoretical exam is taken at a testing room of the municipal authority with extended powers (obecní úřad s rozšířenou působností) and is computer-based, with multiple-choice questions drawn from the official question set for group D. It tests road traffic law and rules, traffic signs, markings and signals, bus handling and driving theory, vehicle construction and technical condition, safe and defensive driving, first aid, driver documentation and obligations, passenger transport specifics including working time and rest, and economical driving. Preparation should combine the current official question set with the official rules of the road, and then real driving practice in a bus. The official body publishes current question counts, time limits, fees and pass thresholds; check its website for the figures that apply when you apply.
What you'll study
About Czech Theory Test D preparation
What does the group D theoretical exam actually test?
It combines road traffic law with bus-specific material: signs and signals, vehicle construction and technical condition, safe driving and hazard perception, first aid, driver documentation, passenger transport rules including working time and rest, and economical driving. Expect questions that only make sense for a bus driver, such as stopping for passengers, load and axle limits, and tachograph duties.
How is the test delivered and how many questions are there?
It is a computer-based multiple-choice test taken in a testing room at the municipal authority with extended powers, with one correct answer per question, using the official question set for group D. The official body publishes the current number of questions, the time limit and the pass threshold; check its website before your appointment rather than relying on older figures.
How difficult is it compared with the car test?
The rules section overlaps heavily with group B, so a car licence holder has a head start. The difficulty comes from the bus-specific material: vehicle construction, passenger safety, working time and rest, and technical condition. Candidates who only revise general traffic rules usually find these parts the hardest, so give them dedicated study time.
How long does preparation usually take?
It depends on your existing licence and experience. If you already hold group B and drive regularly, most of the effort goes into the bus-specific chapters and repeated practice on the official question set. A common approach is several weeks of short daily sessions, then full mock tests until you consistently score well above the threshold.
What should I study first?
Start with traffic rules and signs, because they carry the most weight and underpin the situational questions. Then move to vehicle construction and technical condition, safe driving, and first aid. Leave passenger transport specifics and working time rules for the later phase, when you can connect them to real bus operation.
Can I retake the exam if I fail?
Yes, a failed attempt can be repeated, but the conditions, waiting periods and fees are set by the official framework, not by this page. The municipal authority where you apply publishes the current retake rules and the fee for a repeat attempt, so confirm the details there before booking again.
What are the most common reasons candidates fail?
Underestimating the bus-specific chapters, guessing on questions about technical condition or working time, and not practising under time pressure. Another frequent problem is misreading situational questions that ask what you should do rather than what is permitted. Practising full mock tests under exam conditions exposes both issues early.
Do I need the theory exam before the practical test?
The theoretical examination is normally completed before you proceed to the practical driving test, and your application must be handled by the municipal authority with extended powers. The official body publishes the current sequence, validity of passed parts and the documents you need, so verify the order and deadlines with the authority when you apply.
Is this page an official source?
No. This is independent study material written for candidates preparing for the group D theory exam, and it is not affiliated with or endorsed by any Czech authority. Always rely on the current official question set and the information published by the municipal authority for rules, fees, dates and scoring.
