Making a U-turn is prohibited in any situation that prevents you from verifying that you will not endanger or obstruct other road users, such as on bends and crests with reduced visibility, or in cases of fog or heavy rain.
U-turns are also prohibited:
- At level crossings (not prohibited in their vicinity).
- In tunnels, underpasses and road sections affected by the "Tunnel" sign.
- On motorways and dual carriageways, except in places designated for doing so.
- On one-way roads and road sections.
- On all road sections where overtaking is prohibited, unless the U-turn is expressly authorised.
