U-turnPortugal
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.
Can you U-turn on a Portuguese bridge?
No. The prohibition also covers level crossings and tunnels.
