Traffic rules and road signs
The exam tests this domain by asking you to decode signs and apply the general traffic code: where to drive, when to use lights, what a sign actually requires and which road rules apply on motorways. Many questions turn on a single sign or a single statutory duty.
Sign families and what they require
Danish signs follow the European shape code. Triangles warn; red-bordered circles prohibit or restrict; blue circles give mandatory directions; rectangles inform. A red circle with a number is a maximum speed, not a recommended speed. The octagon is STOP and requires a full stop at the stop line. The inverted triangle means give way (ubetinget vigepligt); you stop only if traffic requires it. A yellow diamond marks a priority road, and the same diamond crossed by a black band ends that priority. Motorway signs introduce motorway rules: no pedestrians, bicycles, mopeds or slow agricultural vehicles; no U-turns, reversing or stopping except in an emergency.
Position, overtaking and lights
Keep to the right and overtake on the left. Overtaking is prohibited at pedestrian crossings and where you cannot see far enough ahead. Signal before changing lane or turning, and cancel the signal. Dipped headlights are required in darkness, rain, fog and other poor visibility; daytime running lights are acceptable in clear daylight. The horn is for warning of danger, not for greeting. When joining a motorway, use the acceleration lane and give way to traffic already on the motorway; the emergency lane is not a driving lane.
Worked example
You pass a blue rectangular motorway sign, then a red circle showing 110. The first sign means motorway rules apply. The second lowers the maximum speed from the general 130 km/h to 110 km/h for that stretch. A moped ahead is not allowed on this road, so you should not treat its presence as normal or follow it closely. Your lawful speed is at or below 110 km/h, further reduced by traffic, weather and visibility.
Traps
Mixing up the warning triangle and the give-way triangle; assuming priority continues after you leave the priority road; using daytime running lights in rain; and overtaking at a pedestrian crossing because no one has stepped onto it yet.
