1What is the legal vehicle scope of a Danish Category C/E driving licence?
A.A large truck over 3,500 kg coupled to a trailer or semi-trailer with a maximum authorized mass over 750 kg
B.A large truck over 3,500 kg coupled only to a light trailer with a maximum mass up to 750 kg
C.A passenger car coupled to a heavy caravan exceeding 3,500 kg combined mass
D.A large bus designed for more than 16 passengers coupled to an unbraked luggage trailer
Explanation: Category C/E entitles the driver to operate a heavy lorry (large truck over 3,500 kg permitted total mass) coupled to one or more trailers or semi-trailers with a permitted total mass exceeding 750 kg. Category C alone only allows trailers up to 750 kg.
2Which driving licence category must you already hold before you can be issued a Danish Category C/E licence?
A.Category B/E (car with heavy trailer)
B.Category C (large truck over 3,500 kg)
C.Category D (large bus)
D.Category C1 (medium truck up to 7,500 kg)
Explanation: To obtain Category C/E in Denmark, you must already hold a valid Category C (stor lastbil) licence. Category C serves as the compulsory legal prerequisite for coupling a heavy trailer over 750 kg to a large lorry.
3What is the standard minimum age to obtain a Category C/E driving licence in Denmark?
A.18 years in all circumstances
B.20 years without any conditions
C.21 years, with exceptions down to 18 years for qualified commercial driver education
D.24 years, matching the standard bus category
Explanation: Under Danish driver licensing executive orders (Kørekortbekendtgørelsen), the normal minimum age for Category C/E is 21 years. Candidates may obtain it at age 18 if they are enrolled in or have completed qualified vocational commercial driver training (erhvervschaufføruddannelse) or military driver training.
4When you successfully pass the driving test for Danish Category C/E, which subcategory are you automatically granted?
A.Category D/E in all cases
B.Category T/M only
C.Category A2
D.Category C1/E
Explanation: Holding Category C/E automatically gives entitlement to drive combinations in Category C1/E (medium truck up to 7,500 kg with heavy trailer), as Category C/E covers all smaller truck combination categories.
5If a driver already holds a valid Category D (large bus) licence and then passes the Category C/E test, what happens to their bus trailer entitlement?
A.They are automatically granted Category D/E and Category D1/E
B.They must complete a separate D/E practical driving test
C.They are only permitted to tow trailers behind buses on private property
D.Their Category D licence is downgraded to Category C/E
Explanation: Under EU and Danish driver licensing rules, a driver who already holds Category D receives Category D/E (and Category D1/E) automatically upon acquiring Category C/E, without needing a separate bus-trailer test.
6Before moving a tractor unit after coupling a semi-trailer, which check best confirms that the fifth-wheel jaws have locked around the kingpin?
A.Check only that the trailer lights illuminate
B.Inspect the locking mechanism and safety latch, then make a gentle pull test with the trailer brakes applied
C.Raise the landing legs before looking at the coupling
D.Assume the jaws are locked whenever the tractor reaches the trailer
Explanation: A visual inspection confirms that the fifth-wheel jaws and safety latch are fully engaged around the kingpin. A gentle pull test with the trailer brakes applied provides a second check before the landing legs are fully raised and the combination enters traffic.
7After connecting a trailer's air lines, what should the driver verify before entering traffic?
A.That both coupling heads can rotate freely while disconnected
B.That reservoir pressure is released before every brake application
C.That pressure builds normally, warnings extinguish, and the trailer service and parking brakes respond correctly
D.That the trailer wheels remain locked when the parking brake is released
Explanation: The driver must confirm adequate system pressure, normal warning indications, and correct operation of both service and parking brakes. A brake response check can reveal a crossed, leaking, or incompletely connected line before road speed is reached.
8What is the main handling risk if cargo is loaded too high on a semi-trailer?
A.The steering becomes lighter only while stationary
B.The trailer's legal length automatically increases
C.The coupling can no longer transmit braking signals
D.The higher centre of gravity increases body roll and rollover risk in curves or sudden manoeuvres
Explanation: Raising the load raises the combination's centre of gravity. Lateral forces in curves or evasive manoeuvres then create a larger overturning moment, so speed and steering inputs must be especially conservative.
9What should a C/E driver do before reversing when mirrors and cameras do not provide a reliable view of the full danger area?
A.Stop and use a competent guide positioned safely where the driver can see them
B.Reverse quickly before another road user enters the area
C.Rely on the reversing alarm to clear the area
D.Open the door and watch only the trailer's left side
Explanation: If the full reversing area cannot be observed reliably, the driver should stop and use a competent guide. The driver and guide must agree signals, maintain visual contact, and stop immediately if contact is lost.
10What is the general maximum speed limit for a Category C/E heavy vehicle combination on Danish motorways, unless signs indicate otherwise?
A.70 km/h
B.80 km/h
C.90 km/h
D.100 km/h
Explanation: Under the Danish Road Traffic Act (Færdselsloven), heavy vehicle combinations exceeding 3,500 kg total mass (Category C/E) are limited to a general maximum speed of 80 km/h on motorways, unless a specific lower posted speed limit applies.

About the Denmark Category C/E Heavy Trailer Theory Test Exam

Denmark Category C/E (stor lastbil med stort påhængskøretøj) is the heavy commercial vehicle combination licence. It covers a large truck over 3,500 kg coupled to one or more trailers or semi-trailers exceeding 750 kg. Candidates must already hold Category C and normally be at least 21 years old, with specified vocational routes available from 18. The official assessment combines a 15-minute digital E-category theory test, passed with errors in no more than three pictures, and a practical test. Official delivery pathways include Danish, English, German, Faroese, and Greenlandic under Færdselsstyrelsen's stated language and interpreter rules.

Assessment

Færdselsstyrelsen administers a 15-minute digital E-category theory test using visual questions with one or more correct responses. Category C/E also requires a separate practical test, including equipment checks, coupling and uncoupling, manoeuvres, and at least 45 minutes of assessed driving. This English-language four-option, one-best-answer bank is a study adaptation, not an official translation, official-format simulation, or substitute for practical driving practice.

Denmark Category C/E Heavy Trailer Theory Test Study Tips from Top Performers

1Master the coupling and uncoupling sequences thoroughly: understand why the yellow control line connects first and disconnects last, and why landing legs and wheel chocks must be set before uncoupling.
2Understand pneumatic fail-safe braking: know how a red supply line rupture triggers automatic trailer emergency braking, and how spring brake cylinders provide mechanical parking security.
3Study combination dynamics and off-tracking: remember that trailer non-steered axles cut the corner inside the tractor track during turns, while drawbar trailer rear overhang swings outward (tail swing).
4Memorize statutory dimensions and weights: 16.50 m for articulated semi-trailers, 18.75 m for drawbar combinations, 25.25 m for modulvogntog, 2.55 m standard width (2.60 m for insulated), 4.10 m height, and at least 25% of combination weight on driving axles.
5Review EU driving and rest rules (Regulation 561/2006): 4.5h driving requires 45 min break (or 15+30 min), 9h daily driving extendable to 10h twice weekly, 11h daily rest (or 3+9h split), and 56 days of tachograph records must be produced during roadside checks.
