Traffic Rules and Road Signs
Default urban speed limit in Denmark is 50 km/h; rural roads 80 km/h; motorways (motorvej) 130 km/h; on roads with a solid centre line and no overtaking, 70 km/h may apply.
Priority to the right applies at unsigned junctions; a driver leaving a private property, parking area, or dirt road must yield to all traffic on the public road.
Roundabouts: vehicles already in the roundabout have priority; entering drivers must yield; indicating left on entry is not required, indicate right when leaving.
Traffic light sequence: red → red+amber → green → amber → red; flashing amber means proceed with caution and yield as at a give-way sign.
A give-way sign (inverted triangle) requires yielding to traffic on the crossing road; a stop sign requires a complete stop at the line before yielding.
Overtaking is prohibited where a solid white centre line is present, at pedestrian crossings, at railway crossings, and where visibility is insufficient; overtaking a tram on the left is generally required.
Safety distance: at least 2 seconds in good conditions; in tunnels, on bridges, and in wet weather increase to 3–4 seconds.
Pedestrian crossings (fodgængerfelt): drivers must yield to pedestrians on or approaching the crossing; stopping or parking within 10 m before a crossing is prohibited.
Vehicle Knowledge and Technical Inspection
Periodic technical inspection (syn) for a light truck (total weight ≤ 3,500 kg) is required every 12 months once the vehicle is 4 years old; new vehicles are first inspected 4 years after first registration.
Inspection covers brakes, steering, suspension, tyres, lights, exhaust emissions, seat belts, and body condition; a failed inspection requires re-inspection within 30 days.
Minimum tyre tread depth for light trucks is 1.6 mm across the central three-quarters of the tread; tyres must be matched in size and construction on the same axle.
Brake system: dual-circuit hydraulic or air; parking brake must hold the vehicle on a 16% gradient; brake fluid is hygroscopic and should be replaced at manufacturer intervals (typically every 2 years).
Lighting: headlights must be correctly aimed; fog lights may only be used when visibility is seriously reduced (generally below 50 m); daytime running lights are mandatory.
A catalytic converter and diesel particulate filter (DPF) are part of emissions control; a DPF warning light requires regeneration or service to avoid failing the smoke opacity test.
Windscreen: cracks in the driver's field of vision are not permitted; wiper blades must clear the screen effectively; washer fluid must be present.
The vehicle's registration certificate (registreringsattest) must be carried or available; the number plate must be legible and correctly mounted.
Load, Weight, and Dimensions
For a category C1 light truck, maximum authorised mass (MAM) is 3,500 kg; the vehicle's own weight plus payload must not exceed MAM.
Maximum axle load must not be exceeded; the load must be distributed so that no axle is overloaded and steering axle load is not reduced below the minimum required for safe steering.
Maximum permitted dimensions for a light truck: width 2.55 m, height 4.0 m, length 12 m for a rigid vehicle; a trailer may increase overall length to 18.75 m.
Load must be secured against shifting, rolling, and falling; use straps, nets, or bars with a combined lashing capacity (LC) at least equal to the load weight times the acceleration factor (typically 0.8 g forward, 0.5 g sideways).
Overhang: load may not project more than 1 m beyond the front or 2 m beyond the rear without marking; rear projection over 1 m must be marked with a red flag or reflective board.
Gross train weight (GTW) is the maximum combined weight of vehicle and trailer; it is stated on the registration certificate and must not be exceeded.
Weight tolerance: a 5% overload may be tolerated for certain enforcement purposes but is not legal; any overload reduces braking and handling and can invalidate insurance.
Load height must not obstruct the driver's view or the lights; the load must not obscure the number plate or rear reflectors.
Driving and Rest Time Rules
EU driving time rules apply to goods vehicles over 3.5 t; a C1 light truck at or below 3.5 t may be exempt from the EU tachograph regulation, but Danish national rules on driving and rest still apply.
EU rules: maximum 9 hours daily driving, extendable to 10 hours twice a week; maximum 56 hours weekly; maximum 90 hours in any two consecutive weeks.
Breaks: after 4.5 hours of driving, a continuous break of at least 45 minutes is required; this may be split into 15 minutes followed by 30 minutes.
Daily rest: at least 11 consecutive hours, which may be reduced to 9 hours up to three times between weekly rests; weekly rest: 45 hours, reducible to 24 hours with compensation.
A tachograph record must be kept for the current day and the previous 28 days; records must be produced on request by enforcement officers.
For vehicles outside the EU tachograph scope, Danish rules require a daily rest of at least 8 hours and a break after 5 hours of driving; check current Danish traffic law for exact exemptions.
Driving time must not exceed the limits even if the vehicle is stuck in traffic; traffic jams do not count as rest.
Weekly rest cannot be taken in the vehicle cab; it must be taken in suitable accommodation.
Safety, First Aid, and Accident Prevention
At an accident: stop, secure the scene (hazard lights, warning triangle at least 50 m behind on rural roads, 100 m on motorways), call 112, and provide first aid.
First aid priorities: airway, breathing, circulation (ABC); do not move an injured person unless there is immediate danger (fire, traffic).
Use the vehicle's first-aid kit and fire extinguisher; a 2 kg dry-powder extinguisher is recommended for light trucks.
Warning triangle is mandatory in Denmark; place it where it is visible to oncoming traffic, not in the driver's own lane.
Safety belt must be worn by driver and all passengers; children under 135 cm must use an approved child restraint.
Fatigue, alcohol, drugs, and mobile phone use are major accident causes; handheld phone use is prohibited while driving.
Defensive driving: maintain a safe following distance, scan ahead 12–15 seconds, and anticipate other road users' mistakes.
In case of brake failure, use engine braking, downshift, and apply the parking brake gradually; do not pump the brake pedal if ABS is fitted.
Environmental Driving and Fuel Efficiency
Fuel consumption increases with speed; driving at 80 km/h instead of 100 km/h can reduce fuel use by 20–30%.
Use cruise control on motorways where safe; avoid rapid acceleration and heavy braking; anticipate traffic flow.
Correct tyre pressure reduces rolling resistance; under-inflation by 0.5 bar can increase fuel consumption by 2–3%.
Idling wastes fuel; switch off the engine when stationary for more than 1 minute (unless in traffic).
Remove unnecessary roof racks and load; aerodynamic drag increases fuel consumption significantly at higher speeds.
Regular servicing (air filter, oil, spark plugs) keeps the engine efficient; a dirty air filter can increase fuel use by up to 10%.
Use the highest gear possible without labouring the engine; change up at around 2,000–2,500 rpm for diesel.
Plan routes to avoid congestion; use eco-driving techniques: smooth acceleration, early gear changes, and reading the road ahead.
Documentation, Registration, and Insurance
A light truck must be registered in the Danish Motor Vehicle Register (Motorregisteret) and have a registration certificate (registreringsattest).
Third-party liability insurance (ansvarsforsikring) is mandatory; driving without it is a criminal offence.
The vehicle must pass periodic technical inspection (syn) and display a valid inspection sticker if required.
EU driving licence category C1 is required for vehicles between 3,500 kg and 7,500 kg; a C1 licence requires a medical certificate and periodic renewal.
For hire or reward, a driver qualification card (chaufføruddannelsesbevis) may be required; check current Danish rules for C1 vehicles.
Road tax (vægtafgift) and insurance must be paid; failure to pay can result in the vehicle being clamped or deregistered.
The registration certificate must be kept in the vehicle or be available for inspection; it contains the vehicle's MAM, axle loads, and dimensions.
When selling a vehicle, the seller must notify the Motor Register within 14 days; the buyer must register the vehicle in their name.
Special Conditions and Hazard Perception
In rain, snow, or ice, increase following distance and reduce speed; braking distance on wet asphalt is roughly double that on dry, and on ice up to ten times.
Aquaplaning occurs when water depth exceeds tyre tread; ease off the accelerator, do not brake hard, and hold the steering steady.
Fog: use fog lights only when visibility is below 50 m; reduce speed and use dipped headlights; do not use full beam.
Ice and snow: use winter tyres (mandatory in winter conditions in many EU countries; in Denmark, winter tyres are not legally required but recommended).
Strong crosswinds affect high-sided vehicles; reduce speed and be prepared to correct steering, especially on bridges and open stretches.
Tunnels: switch on dipped headlights, keep a safe distance, and observe variable speed limits; in case of fire, stop, switch off engine, and evacuate to the nearest exit.
Night driving: reduce speed so you can stop within the illuminated distance; use dipped headlights when meeting traffic.
Hazard perception: scan for pedestrians, cyclists, and children near schools, bus stops, and parked cars; anticipate door opening and sudden crossings.
