About this exam

The KRESZ D theory examination is the Hungarian knowledge test that a candidate must pass to obtain a category D (bus) driving licence. It is aimed at drivers who already hold a lower category licence and want to carry passengers professionally, as well as at people entering passenger transport work. The computer-based test is delivered in Hungarian and covers the rules of the road, road signs and markings, priority at junctions and roundabouts, speed and following distances for heavy vehicles, category D vehicle knowledge such as dimensions, braking systems and passenger doors, passenger transport rules, driving and rest periods with tachograph obligations, hazard perception scenarios and basic first aid. Preparation works best in layers: first the general KRESZ rules and signs until recognition is automatic, then the bus-specific material on mass, braking and passenger safety, then timed practice on scenario questions. Because a bus is long, heavy and full of people who are not wearing seat belts, examiners expect you to reason about stopping distance, blind spots and passenger movement rather than just recall single rules. The Hungarian authority responsible for driving licensing publishes the current question count, time limit, pass mark and fee; confirm these on its official site before booking, as this page does not state them.

Common questions

About Hungary KRESZ D preparation

What format is the KRESZ D theory exam?

It is a computer-based, multiple-choice test delivered in Hungarian. You answer by selecting from the offered options on screen, and the result is produced automatically at the end of the test. The official licensing authority publishes the current structure and the exact number of items, so check its website rather than relying on older candidate accounts.

How hard is it compared with the category B theory test?

The general rules overlap heavily with category B, but the bus-specific layer is what catches people. Questions on air braking, vehicle length and height, door safety, standing passengers and tachograph rules require understanding rather than recognition. Candidates who already drive confidently often underestimate this part and need extra study time.

Can I retake the exam if I fail?

Retakes are possible, but the conditions, waiting period and any additional fee are set by the Hungarian licensing authority and can change. Confirm the current retake rules on its official site or at the driving school where you register. Do not assume you can simply rebook the next day.

How long does the test take and what is the pass mark?

Those figures are published by the official Hungarian authority responsible for driving licensing and are not fixed on this page. Look them up on its website before your appointment so you know how many items you face, how much time you have and what score you must reach.

In what order should I study the topics?

Start with general KRESZ rules, signs and markings until they are automatic, because they underpin everything else. Then move to priority situations and speed and distance calculations. Only after that take on bus-specific vehicle knowledge, passenger transport rules and tachograph and rest-period material, finishing with timed scenario practice.

What do candidates most often get wrong?

The most common failures are stopping-distance and following-distance questions for heavy vehicles, priority at unmarked junctions, and tachograph and rest-period rules. Many also misjudge questions about standing passengers and door safety. These are exactly the areas where a bus differs from a car, so give them dedicated practice.

Do I need first aid knowledge for this exam?

Yes, a small part of the test covers first aid and accident handling, including how to secure a scene and what to do before emergency services arrive. It is a minor share of the questions but easy marks if you study the standard Hungarian first aid guidance for drivers.

Is this page an official source?

No. This is independent study material written to help you prepare. It is not affiliated with any Hungarian authority, driving school or examination body. Always confirm exam logistics and legal requirements with the official licensing authority and your registered driving school before booking.
