1What is the primary vehicle entitlement granted by a Danish Category D/E driving licence?
A.A Category D bus coupled to a trailer with a maximum authorized mass exceeding 750 kg
B.A Category D bus coupled only to a lightweight utility trailer with a maximum authorized mass up to 750 kg
C.An articulated bus with permanently coupled passenger sections carrying standing commuters
D.A heavy commercial truck coupled to a drawbar trailer exceeding 3,500 kg
Explanation: Category D/E entitles the holder to drive a Category D bus coupled to a trailer with a maximum authorized mass exceeding 750 kg. A standard Category D entitlement covers the bus with a trailer up to 750 kg.
2How does Danish traffic law legally distinguish an articulated bus (ledbus) from a Category D/E bus-trailer combination?
A.An articulated bus is a single rigid vehicle structure requiring Category D, whereas a bus towing a separate trailer over 750 kg requires Category D/E
B.An articulated bus always requires Category D/E because it consists of two distinct articulated chassis sections
C.A bus towing a trailer is treated as an articulated bus once the trailer length exceeds 6 metres
D.An articulated bus requires Category D/E only if passenger seating exceeds 60 seats
Explanation: Under Danish vehicle regulations, an articulated bus is constructed and registered as a single motor vehicle with permanently interconnected passenger sections, requiring only a Category D licence. A bus towing a detachable trailer with a maximum authorized mass above 750 kg is a vehicle combination and legally mandates Category D/E.
3What is the maximum statutory length permitted for a standard bus-and-trailer road combination in Denmark?
A.18.75 metres
B.16.50 metres
C.20.50 metres
D.25.25 metres
Explanation: Under Danish vehicle dimension regulations (Dimensionsbekendtgørelsen) and EU standards, the maximum permitted total length of a vehicle train consisting of a bus and a drawbar trailer is 18.75 metres.
4What is the standard maximum permitted width for a Category D/E bus-trailer combination in Denmark?
A.2.55 metres (2.60 metres for temperature-controlled refrigerated trailers)
B.2.50 metres under all circumstances
C.2.75 metres including all wing mirrors and side markers
D.3.00 metres for long-distance international coaches
Explanation: In Denmark, the general statutory width limit for road vehicles and combinations is 2.55 metres, with an exception allowing up to 2.60 metres for conditioned bodies with thick insulated walls.
5What is the maximum statutory vehicle height allowed for a bus and its trailer on Danish public roads?
A.4.10 metres
B.4.00 metres
C.4.25 metres
D.4.50 metres
Explanation: Under Danish dimension regulations, the maximum overall height for road vehicles and combinations is 4.10 metres. While the EU Directive baseline is 4.00 metres, national Danish regulations permit vehicles up to 4.10 metres without special dispensation.
6What does Danish traffic legislation (Færdselsloven) state regarding the transport of passengers inside a trailer coupled to a bus?
A.Carrying passengers inside a trailer is strictly prohibited under all circumstances
B.Passengers may be seated in the trailer only if it is equipped with type-approved safety belts and an intercom system
C.Tour group guides may ride in the trailer to manage baggage distribution during transit
D.Passengers may occupy the trailer during daylight hours on urban routes
Explanation: Section 38 of the Danish Road Traffic Act (Færdselsloven) strictly prohibits the carriage of persons in a trailer or semi-trailer coupled to a motor vehicle. A bus trailer must be used solely for luggage, sports gear, equipment, or goods, and never for passenger transit.
7Under Danish heavy vehicle regulations, what minimum percentage of a loaded vehicle combination's actual total weight must rest on the driving axles?
A.At least 20%
B.At least 15%
C.At least 35%
D.At least 50%
Explanation: For a registered trailer coupled to a motor vehicle over 3,500 kg, the current Danish dimensions-and-weight order requires at least 20% of the combination's actual total weight to rest on the towing vehicle's driven wheels.
8A two-axle Category D touring coach with a maximum permissible weight of 18,000 kg is coupled to a luggage trailer with a permissible weight of 3,500 kg. What is the total authorized combination mass?
A.21,500 kg
B.18,000 kg
C.24,000 kg
D.28,000 kg
Explanation: The maximum permissible combination mass is determined by adding the maximum authorized mass of the bus (18,000 kg) and the maximum authorized mass of the trailer (3,500 kg), which equals 21,500 kg, provided this does not exceed the bus's certified maximum combination train weight.
9What is the statutory maximum axle load permitted on a single driven axle of a heavy vehicle in Denmark?
A.11.5 tonnes
B.10.0 tonnes
C.12.5 tonnes
D.13.0 tonnes
Explanation: In Denmark and across the European Union, the statutory limit for a single driving axle is 11.5 tonnes, whereas a single non-driving axle is generally limited to 10.0 tonnes.
10Where can a driver verify the maximum permissible trailer weight that a specific bus is certified to tow?
A.On the bus's registration certificate (registreringsattest) and the manufacturer data plate on the coupling
B.On the trailer's tyre pressure decal located near the mudguards
C.By calculating exactly 50% of the bus's unladen kerb weight
D.In the standard national highway code booklet
Explanation: The maximum trailer weight a bus may legally tow is formally stated on the bus's registration certificate (Part I) and must not exceed the D-value and maximum towing capacity specified on the coupling mechanism's approved approval plate.

About the Denmark Category D/E Bus Trailer Theory Test Exam

Denmark Category D/E (stor bus med stort påhængskøretøj) is the heavy commercial passenger combination licence. It entitles the holder to drive a Category D bus (large bus designed to carry more than 8 passengers) coupled to a trailer or semi-trailer with a maximum authorized mass exceeding 750 kg, such as passenger luggage trailers, ski trailers, bicycle transport trailers, and commercial utility trailers. Under Danish traffic law (Færdselsloven), transporting passengers inside any trailer is strictly prohibited under all circumstances. Candidates must already hold a valid Category D licence and normally be at least 24 years of age, with fast-track routes at age 21 or 18 for drivers enrolled in or having completed qualified professional commercial bus driver training (grundlæggende kvalifikationsuddannelse / erhvervsuddannelse som buschauffør). Official delivery pathways include Danish, English, German, Faroese, and Greenlandic under Færdselsstyrelsen interpreter and test guidelines.

Assessment

Færdselsstyrelsen administers a 15-minute digital E-category theory test using visual questions with one or more correct responses. Category D/E also requires an official practical driving test of at least 45 minutes, including coupling and uncoupling procedures, safety checks, reversing with pivot point, and road 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 training.

Denmark Category D/E Bus Trailer Theory Test Study Tips from Top Performers

1Master drawbar coupling checks: assess play with the approved wear indicator or manufacturer limit, verify the safety indicator is fully locked, and perform the prescribed security check before travel.
2Understand two-line pneumatic brake operation: remember that the red supply line charges trailer reservoirs and releases spring parking brakes, while the yellow control line transmits service braking pressure. Rupture of the red line immediately triggers automatic emergency braking.
3Thoroughly review combination dynamics: high-deck buses have a long rear overhang that swings outward when turning, violently displacing the drawbar, while the trailer's axles cut the corner (off-tracking) on the inside of the turn.
4Understand tongue weight (støttelast) principles: central-axle luggage trailers require positive vertical hitch load. Negative vertical load lifts the bus rear axle, severely compromising steering control and destabilizing the combination.
5Learn reversing principles and banksman rules: reversing a turntable drawbar trailer involves two pivot points, requiring precise counter-steering. If using a banksman, you must maintain eye contact in your exterior mirror at all times; stop immediately if the banksman leaves your field of vision.

Frequently Asked Questions

What is the legal vehicle scope of a Danish Category D/E driving licence?

Category D/E entitles the driver to operate a vehicle combination consisting of a Category D bus (large bus designed to carry more than 8 passengers) coupled to a trailer or semi-trailer with a maximum authorized mass exceeding 750 kg, such as heavy luggage, bicycle, or ski trailers. Passengers may never be transported inside the trailer.

Is an articulated bus (ledbus) classified as a Category D/E combination?

No. An articulated bus is legally classified as a single vehicle with a permanently articulated passenger section, requiring only a Category D licence. Category D/E is exclusively required when a bus is coupled to a separate trailer exceeding 750 kg.
