ExploreAbout this exam
The Norwegian Category D theory test is the knowledge component of the driving licence required to drive a bus - a vehicle designed and constructed for carrying more than eight passengers in addition to the driver. You need it if you are training for a professional bus career, upgrading from a lighter category, or renewing competence in some situations. The test is computer-based, multiple choice, and is taken at an approved test centre, typically through Statens vegvesen or a trafikkskole. Questions are drawn from the full breadth of bus driving: traffic rules and signs, vehicle technology and inspection, driving technique with a long, heavy vehicle, hazard perception and defensive driving, passenger safety and evacuation, driving and rest time with the tachograph, loads and dimensions, first aid and fire protection, and environment and economy. Preparation works best in layers: master traffic rules first, since they underpin every other topic; then vehicle knowledge and handling; then passenger safety and duty-time rules, which are where professional drivers most often lose marks. Practise with realistic multiple-choice sets, review every wrong answer against the regulation behind it, and read the current official guidance on Statens vegvesen's website for the rules that apply to your licence class and any recent changes.
What you'll study
About Norway Category D Bus Theory Test preparation
How many questions are on the test, and how long do I have?
The number of questions and the time limit are set by the authorities and can change. Statens vegvesen publishes the current figure for Category D on its website, and your trafikkskole will confirm it when you book. Do not rely on numbers from older forum posts or previous versions of the test.
What score do I need to pass?
The passing score is determined by the exam authorities and is not fixed in public study material. Check the current requirement on Statens vegvesen's site before your test day. Aim well above the minimum in practice anyway, since a comfortable margin protects you against a few careless mistakes on the day.
How much does the test cost, and how do I book it?
Fees are set and updated by the authorities and vary by location and provider. The current fee and booking process are published by Statens vegvesen and by approved trafikkskoler. Book early in busy periods, and confirm whether your booking is through the public test centre or your driving school.
Can I retake the test if I fail, and how soon?
Yes, retakes are normally possible, but the waiting period and any extra fee are set by the authorities and can change. Statens vegvesen publishes the current retake rules. Use the waiting time to review your weak domains rather than simply rebooking and hoping for a different question mix.
Is the test hard?
It is not designed to trick you, but it is broad. Most candidates find traffic rules and passenger safety manageable and struggle with driving and rest time, tachograph rules and vehicle technology, because those are specific and easy to confuse. Treat the test as a professional exam, not a formality, and prepare across all domains.
In what order should I study the topics?
Start with traffic rules and road signs, because every other domain assumes them. Then vehicle knowledge and driving technique, then passenger safety and evacuation. Add driving and rest time, loads and dimensions, first aid and fire protection, and finish with environment and eco-driving. This order builds from foundations to specialised professional duties.
What do candidates most often get wrong?
Common failure points are duty and rest time calculations, tachograph use, emergency exit and evacuation procedures, and load and dimension limits. Candidates also lose marks by skimming questions - many ask for the safest action, not the most convenient one. Read each question fully and eliminate options that are legal but unsafe.
Do I need to take a practical test as well?
Yes. The theory test is only one part of obtaining the Category D licence; a practical driving test and other requirements also apply. Statens vegvesen sets the full sequence and any prerequisites, such as first aid training or medical requirements. Confirm the complete path for your situation before you start.
How should I use practice tests?
Use them as diagnostics, not as a scoreboard. After each set, write down why every wrong answer was wrong and which regulation it comes from. Revisit those topics in the source material, then retest after a few days. Spaced repetition on your weak domains beats doing endless full sets without review.
