Turn prohibitionDenmark
1. Turn prohibition
A turn prohibition prevents drivers from turning in the direction indicated by a traffic sign. It may prohibit a left turn, a right turn or a U-turn at an intersection or along a specified section of road.
Drivers must continue along a permitted route and follow any lane arrows or mandatory-direction signs. A turn prohibition does not itself determine priority or speed, and any exemption for cyclists, public transport or other road users must be expressly indicated.
What does a no-turn sign prohibit in Denmark?
It prohibits the left, right or other turn shown at the junction or position controlled by the sign in Denmark. Follow any supplementary panel or authorised direction and choose another legal route.

Does a no-left-turn sign always prohibit a U-turn in Denmark?
Yes. In Denmark, the signing regulation expressly states that a no-left-turn sign also prohibits a U-turn. The C11/C12 restrictions normally concern the junction or entrance where the sign is installed, unless a supplementary plate specifies otherwise. Do not assume a separate U-turn sign is always needed.

Can a no-turn restriction apply only to certain vehicles or hours in Denmark?
Yes, where the local sign system provides a supplementary condition or exemption, such as a vehicle class, time or authorised access. Without a valid exception, comply with the prohibited movement shown.
