These signs are crucial for preventing dangerous traffic movements and ensuring smooth traffic flow, especially in areas where visibility is limited or junctions are complex. Always check for any additional plates that might specify exceptions and be prepared to find an alternative, legal route.

Prohibitory signs are legally binding signs that prevent unsafe or unsuitable traffic movements.

Drivers should identify whether the restriction applies to them before entering the controlled area and should choose another lawful route if necessary. Official French sign code: B2c.
"No U-turns" tells drivers that a movement, access, vehicle category, stopping action, dimension, weight, or behaviour is prohibited. The restriction applies from the sign unless a plate or road layout states otherwise.
Get clear, practical answers to the most common questions about the B2c - No U-turns road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the French driving theory exam in France.
The B2c sign, which displays a red circle with a red border and a black U-turn symbol crossed out, means that making a U-turn is prohibited at this location. This is a strict prohibition that drivers must adhere to. If you see this sign, you must not attempt a U-turn.
While the B2c sign itself represents a complete prohibition, always check for supplementary plates below it. These plates can modify the restriction by applying it only to certain vehicle categories, during specific times, or in particular directions. If no supplementary plate is present, the prohibition is general and absolute.
If you see the B2c 'No U-turns' sign and your intended manoeuvre is prohibited, you must not perform the U-turn. Instead, you should continue driving and look for another legal opportunity to turn around. This might involve proceeding to the next junction, a designated turning area, or following a route indicated by other traffic signs.
A common trap is assuming a U-turn is allowed if other drivers are doing it, or if there's no immediate danger. The B2c sign is a legal prohibition, regardless of other drivers' actions. Another mistake is not checking supplementary plates, which can specify limitations. Always obey the sign until you see an end-of-restriction sign or a new instruction.
You'll often find the B2c 'No U-turns' sign on roads where a U-turn would be particularly hazardous. This includes busy main roads, areas with poor visibility, near junctions or roundabouts, on narrow roads, or in sections where traffic speeds are high. Their purpose is to prevent potential head-on collisions or disruptions to traffic flow.
