1. Road narrowing

A road narrowing is a section where the available width of the road or carriageway becomes smaller. The narrowing may occur on both sides, on one side only, or because one or more traffic lanes end.

Drivers should reduce speed, observe approaching and adjacent traffic, maintain sufficient lateral clearance and merge when necessary. Warning signs do not always determine priority, so drivers must follow any priority signs, lane markings and local traffic rules.

What does a road-narrowing warning mean in Denmark?

Danish warnings distinguish a narrower carriageway from the merging or ending of traffic lanes. Read the actual layout and allow enough space for vehicles travelling in both directions.

Does a narrowing warning give you priority in Denmark?

No. A warning describes the reduced width, rather than allocating priority or setting a numerical speed limit. Follow any separate priority signs, signals and meeting rules, and slow enough to pass safely or wait before entering.

What should you do if traffic lanes merge at a narrowing in Denmark?

In Denmark, E16.1 indicates a lane reduction with merging and mutual consideration under section 18(4). E16.2 indicates a lane change: the driver moving across must ensure it causes no danger or unnecessary inconvenience under section 18(2). Read the actual sign and markings; the duties differ even where both layouts narrow to fewer lanes.
