Turn prohibitionNorway
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 Norway?
It prohibits the left, right or other turn shown at the junction or position controlled by the sign in Norway. Follow any supplementary panel or authorised direction and choose another legal route.

Does a no-left-turn sign always prohibit a U-turn in Norway?
Norway separately prescribes 330, svingeforbud, for a prohibited turn and 332, vendingsforbud, for a prohibited U-turn. Sign 330 applies at the indicated junction or the first junction after it, unless a supplementary plate shows another extent. Check the actual controls and manoeuvre rules before turning.

Can a no-turn restriction apply only to certain vehicles or hours in Norway?
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.
