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: B1.
"No entry" 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 B1 - No entry 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 primary purpose of the B1 'No Entry' sign is to prohibit drivers from entering a specific road, area, or continuing a movement. It's a mandatory sign that enforces restrictions on traffic flow for safety or regulatory reasons.
The B1 sign generally prohibits entry into the area or road it controls. Depending on supplementary plates, it can also prohibit stopping, parking, turning, overtaking, or specify vehicle types, dimensions, or weights that are not allowed.
Yes, absolutely. Supplementary plates attached to the B1 sign can significantly alter its meaning by limiting the restriction to specific vehicle categories (e.g., trucks, motorcycles), times of day, distances, or directions. Always read these carefully before deciding your next move.
If the B1 'No Entry' sign prevents you from continuing on your intended path, you must find and follow an alternative, legal route. Do not assume you are exempt, and do not follow other drivers if they appear to ignore the sign, as the restriction still applies to you unless explicitly exempted.
The prohibition imposed by a B1 'No Entry' sign remains in effect until you see an official end-of-restriction sign (like 'End of Prohibition'), reach a zone exit, or encounter a new traffic sign or road marking that changes the rule. Do not assume the restriction ends automatically.
A common trap is assuming the sign only means 'do not enter'. Learners can also misunderstand how supplementary plates modify the restriction or fail to recognise that ignoring the sign is an offence, even if others do. Always check for plates and obey the rule until it officially ends.
