Iceland
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 Iceland?
The turn-ban sign prohibits the direction shown at the junction or equivalent location and also prohibits turning the vehicle round there. Follow any applicable supplementary information and choose a permitted route.

Does a no-left-turn sign always prohibit a U-turn in Iceland?
Yes. The Icelandic turn-prohibition sign also prohibits turning the vehicle round at the controlled junction or comparable location. A separate no-U-turn sign prohibits turning round. Read any valid supplementary conditions; do not treat a no-left-turn sign as permission for a U-turn.
