ExploreAbout this exam
The Danish C/E theory test is the written step towards the heavy-trailer entitlement added to a Category C lorry licence. It is aimed at drivers who already hold C and want to pull trailers above the weight threshold that separates light trailers from heavy combinations - typically articulated units and drawbar combinations used in distribution, construction and long-haul work. The test is delivered in Danish on a computer at an approved test centre, using multiple-choice questions. Content follows the national driver-training curriculum: traffic law and signage as they apply to long, heavy vehicles, coupling and articulation, masses and dimensions, stability and handling, load securing and weight distribution, air brakes and coupling checks, driver hours and tachograph rules, hazard perception, vehicle defects and inspection, plus first aid and economical driving. Preparation works best in layers. Learn the vehicle-combination material until coupling and brake checks are automatic, then drill the rules that differ from car driving, and finish with timed practice so the wording of the questions feels familiar. Your driving school's theory materials and the Danish road-safety authorities' published guidance are the sensible anchors. The official body that administers the test publishes current logistics - question count, time allowed, fee, pass mark and retake rules - so check its site rather than relying on second-hand numbers.

What you'll study
About Denmark Category C/E Heavy Trailer Theory Test preparation
What format is the C/E theory test in?
It is a computer-based multiple-choice test taken at an approved test centre, delivered in Danish. You answer on screen and get your result afterwards. The exact number of questions and the layout of the screens are set by the administering body, which publishes the current specification on its website.
How long does the test take, and how many questions are there?
Those figures are set centrally and can change, so they are not repeated here. The official body responsible for the Danish driving tests lists the current question count, time allowance and pass mark. Check that source before you book, and again close to your test date.
How hard is it compared with the Category C theory test?
Most candidates find the traffic-law portion familiar from C. The new difficulty is combination-specific: articulation and off-tracking, mass and dimension limits, coupling and air-brake checks, and load distribution. If you rush those topics you will lose marks even with strong general road knowledge.
What if I fail - can I retake it?
Yes, retakes are possible, but the waiting period, fee and any limit on attempts are set by the administering body and are not fixed here. Confirm the current retake rules on its website when you book, and use the gap to work on the specific topics you missed rather than rereading everything.
In what order should I study the topics?
Start with vehicle-combination knowledge - coupling, articulation, masses, brakes - because those ideas underpin the driving-technique questions. Then take traffic law and signs, load securing, and driver hours. Leave hazard perception and first aid until the core is solid, and finish with timed mixed practice.
Where do candidates usually lose marks?
Common weak spots are mass and dimension limits, the correct sequence for coupling and uncoupling, air-brake pressure checks, and load distribution over the axles. Driver hours and tachograph rules also catch people who assume car rules apply. These are precise, rule-based topics where guessing does not work.
Does holding C/E change what I may drive?
The heavy-trailer entitlement extends what your lorry licence covers to combinations above the light-trailer limit. Exact mass thresholds and any conditions attached to the category are defined in Danish licensing rules; check the official guidance rather than assuming a figure, since limits are amended from time to time.
Is this page an official source?
No. It is independent study material written to help you prepare and understand what the test covers. It is not affiliated with, endorsed by or connected to any Danish authority, test centre or driving school. For binding information on rules, fees and booking, use the official body's own publications.
