The B11 sign signifies that a certain width is prohibited. This means vehicles exceeding the specified width are not allowed to proceed past the sign. It's a prohibitory sign that requires drivers of affected vehicles to find an alternative route.
Before you reach the sign, you must read it carefully, including any supplementary plates. These plates often specify which vehicles or dimensions are restricted. If your vehicle exceeds the stated width, you must not enter the restricted area and should immediately plan and take a different, legal route.
Exemptions are usually indicated on supplementary plates beneath the main B11 sign. These plates might specify that the restriction applies only to certain types of vehicles, during specific times, or for a certain distance. Never assume you are exempt unless your vehicle type or situation is clearly stated on the plate.
A common trap is assuming the restriction doesn't apply to you without carefully checking any supplementary plates. Learners might also hesitate too long before choosing an alternative route, or mistakenly believe they can follow another vehicle that might be exempt. Always assess the restriction for your own vehicle well in advance.
While the primary meaning of the B11 sign is a restriction on vehicle width for movement, prohibitory signs can also affect stopping or parking if indicated by supplementary plates or the context of the restriction (e.g., a narrow alleyway where any vehicle exceeding a certain width cannot even stop without blocking access). However, its core function is about preventing passage for vehicles of excessive width.
