About this exam

The Danish C1/E theory test is the knowledge component of the driving licence category that lets you drive a light lorry (over 3,500 kg up to 7,500 kg) with a trailer whose permitted maximum weight exceeds 750 kg. It is aimed at candidates who already hold a C1 licence, or who are taking C1 and E together, and who need to prove they understand the rules and risks specific to a coupled vehicle. The test is delivered in Danish as a computer-based multiple-choice examination, and the questions probe road traffic law, coupling and load distribution, handling and reversing technique, observation and hazard perception, vehicle checks, driving and rest periods with tachograph use, accident response and first aid, economical driving, and driving in weather, darkness and on different road types. Preparation works best in layers: secure the traffic-law basics first, then practise the physical procedures - hitching, weight checks, reversing - until they are automatic, and finish with timed practice on full sets so that reading speed and decision rhythm are trained, not just recall.

What you'll study

Common questions

About Denmark Category C1/E Light Lorry Trailer Theory Test preparation

How many questions are on the test, and how long do I have?

The question count and time limit are set by the Danish authorities and are adjusted from time to time. Rather than relying on a figure from a forum or an old course handout, check the current details on the official body's website before you book, and use practice sets of whatever length you find there to rehearse your pacing.

What score do I need to pass?

The passing score is determined by the authority that administers the test and is not fixed permanently. Look it up on the official site when you register. In practice, aim well above the minimum in your practice sets, because a comfortable margin protects you against a few careless errors on the day.

Is the test in Danish only?

The test is delivered in Danish, and the terminology around weights, coupling and tachographs is Danish. If Danish is not your first language, build a small vocabulary list of vehicle-combination terms early, so that a language gap does not masquerade as a knowledge gap during the exam.

How difficult is the C1/E theory test compared with the car test?

Most candidates find it harder, mainly because the material is broader. You must combine general traffic law with combination-specific weight rules, coupling procedures and tachograph obligations. The individual questions are rarely tricky; the difficulty lies in the volume and in the precision required on numbers and definitions.

What do candidates most often get wrong?

Recurring weak spots are weight and payload calculations, the difference between permitted maximum weight and actual laden weight, correct coupling and uncoupling order, and the rules on driving and rest periods. Reversing and observation questions also catch people who have memorised rules but never pictured the manoeuvre.

In what order should I study?

Start with road traffic law and basic vehicle knowledge, since everything else assumes them. Then work through coupling, loading and weight distribution, followed by handling and observation. Leave tachograph and rest-period rules for a dedicated block, because they are detail-heavy, and finish with full timed practice sets.

Can I retake the test if I fail?

Retake rules and any waiting period or fee are set by the authority and can change. Check the official site for the current procedure before assuming you can simply rebook the next day. Use any waiting time to review which domains produced your errors rather than rereading everything.

How should I use practice questions effectively?

Answer before looking at the explanation, then write down why the wrong options were wrong. Group your mistakes by domain so you can see whether the problem is law, weights or technique. Retest the same domain a few days later; recognising an explanation is not the same as producing the answer under time pressure.

Does holding a C1/E licence change my driving and rest period obligations?

Goods transport above certain weight thresholds brings EU driving and rest period rules and tachograph requirements into play, and the C1/E test checks that knowledge. The precise thresholds and exemptions matter, so confirm the current rules on the official authority's pages rather than relying on summary tables.

What happens at the test centre?

You register with identification, are seated at a computer terminal, and answer multiple-choice questions within the allotted time. Read each question fully, since options often differ by a single weight figure or a word such as 'permitted' versus 'actual'. Flag uncertain items and return to them if the system allows.
