U-turnAustria
1. U-turn
A U-turn is a driving manoeuvre in which a vehicle turns around to travel in the opposite direction. It normally involves crossing part of the roadway and re-entering traffic facing the direction from which the vehicle came.
Before making a U-turn, the driver should check surrounding traffic, pedestrians and cyclists, signal when required and make sure there is enough visibility and space to complete the manoeuvre safely. U-turns may be prohibited by traffic signs or on particular types of roads.
May an Austrian U-turn force other road users to stop?
No. It must neither endanger nor obstruct other road users.
Can you make a U-turn in heavy Austrian traffic?
No. Section 14 prohibits turning around in heavy traffic.
Does an Austrian no-left-turn restriction also prohibit turning around there?
Yes. Section 14 includes places subject to that restriction.
