ExploreAbout this exam
The Danish C1 theory test (kategori C1 teoriprøve) is the written component of the licence that lets you drive a light lorry - a goods vehicle with a permissible maximum weight above 3,500 kg and up to 7,500 kg, usually with a trailer of up to 750 kg. Drivers often take it to move up from an ordinary B licence for work in delivery, trades, utilities or transport, and it is also the natural stepping stone towards the full C licence. The theory test is delivered as multiple choice at a Danish driving-test centre, in Danish, and it draws on the same road-sign, right-of-way and hazard-perception foundation as the car test but adds material specific to heavier vehicles: load securing and axle loads, vehicle dimensions and weights, tachograph and driving/rest time rules, pre-departure checks, and the braking and blind-spot characteristics of a lorry. Preparation means working systematically through the official theory syllabus, using current Danish learning materials, and practising until sign recognition and hazard clips become automatic. Candidates who already hold a B licence should not assume the C1 test is the car test with a few extra questions - the load, weight and rest-time domains fail people who skip them.

What you'll study
About Denmark Category C1 Light Truck Theory Test preparation
What does a C1 licence actually let me drive?
A lorry with a permissible maximum weight over 3,500 kg but not more than 7,500 kg, designed and constructed for carrying goods, plus a trailer up to 750 kg. Heavier combinations and buses require other categories. Check the current definitions on the Danish driver-licence authority's site before you book.
Is the C1 theory test different from the car theory test?
Yes. The road-sign and right-of-way basics overlap, but C1 adds vehicle weights and dimensions, load securing, tachograph and driving/rest time rules, and lorry-specific hazard perception. Treat it as a new syllabus rather than a short extension of the B test.
How many questions are there and how long do I have?
The Danish authority sets and periodically revises the question count, time allowance and pass mark, so figures circulating online go stale. Look up the current test specification on the official driver-licence website rather than relying on a forum post or an old app.
How hard is it, and where do candidates lose marks?
Most failures come from the load, weight and rest-time domains, not from signs. Candidates underestimate axle-load and securing questions, and misjudge stopping distances and blind spots for a heavier vehicle. Practice those areas until they are as familiar as the sign questions.
What happens if I fail - can I retake it?
Yes, retakes are possible, and there is normally a waiting period and a fee for each attempt. The exact rules and current fee are published by the Danish driver-licence authority. Book through your driving school or the test booking system, and use the failure report to target your weak domain.
In what language is the test delivered?
The Danish C1 theory test is delivered in Danish. If Danish is not your first language, build vocabulary for vehicle weights, load securing and rest-time terms early, because those questions are wording-sensitive. Ask your driving school about the options available to you.
Do I need a medical certificate and a theory course first?
C1 requires a health declaration and a medical examination appropriate to the category, and most candidates train through an approved driving school. Requirements and validity periods change, so confirm the current sequence of steps with the authority or your school before paying for anything.
What is the best study order?
Start with signs and right-of-way to build confidence, then move to vehicle knowledge and load/weight, which carry real weight in the scoring. Add driving and rest time rules next, then environmental driving and documentation. Finish with hazard-perception practice under time pressure.
Can I prepare with a C1 app instead of a theory course?
Apps and online question sets are useful for repetition and for spotting weak domains, but they are not official and may lag behind rule changes. Use them alongside current Danish learning material and the syllabus from your driving school, and always verify numbers against the authority.
