Get clear, practical answers to the most common questions about the B15 - Give priority to oncoming vehicles 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 B15 sign means you must not proceed into a section of road if it would force oncoming vehicles to stop or manoeuvre to let you pass. You must wait until the oncoming traffic has cleared the section before you can proceed. It's about ensuring safe passage for all vehicles in restricted spaces.
You'll often see the B15 sign on narrow roads, bridges, tunnels, or at the entrance to areas where two-way traffic cannot easily pass each other. It's used to manage traffic flow and prevent gridlock or accidents in constrained environments.
A common mistake is assuming you can proceed if the oncoming vehicle is also slowing down or if the road looks wide enough. The B15 sign is absolute: if another vehicle is approaching and you can't pass side-by-side without issue, you must wait. Another trap is assuming the restriction ends because other drivers ignore it; you must always obey the sign yourself.
You don't necessarily need to stop completely, but you must slow down early and be prepared to stop if necessary. The key is to assess the oncoming traffic. If there are no oncoming vehicles, or if they are far enough away that you can safely pass, you may proceed. However, if there is any doubt, you must yield.
Supplementary plates provide crucial additional information that modifies the sign's restriction. For example, a plate might specify certain vehicle types (like trucks or buses) that must give way, or it might indicate a specific distance or time period for the restriction. Always read any supplementary plate carefully before deciding your action.
