The B0 'No Vehicles' sign is a prohibitory traffic sign meaning that a specific restriction applies. This restriction could relate to vehicle entry, a particular movement like turning or overtaking, stopping, parking, vehicle dimensions, weight, or even the use of horns. It is a legally binding sign that prohibits what is indicated.
When you see the B0 'No Vehicles' sign, you must first read any supplementary plates attached to it. These plates will clarify exactly what is prohibited for whom, when, or where. If the restriction applies to you and prevents your intended movement, you must find a lawful alternative route before reaching the restricted point.
While the B0 sign itself is a general prohibition, supplementary plates often specify exemptions. For example, a plate might indicate the restriction applies only to vehicles over a certain weight or to goods vehicles. Never assume an exemption applies unless your vehicle type, situation, or time of travel is clearly stated as exempt on the sign or plate.
A common mistake is not paying attention to supplementary plates, leading learners to assume the restriction applies to them when it doesn't, or vice-versa. Another trap is proceeding into a restricted area because other drivers are doing so; the prohibition remains legally binding for you. Always check for end signs or new instructions before assuming the restriction no longer applies.
Not necessarily. The B0 sign indicates a prohibition, but the restriction can be very specific. It might prohibit entry for certain vehicle types (e.g., heavy goods vehicles), prevent specific actions (e.g., overtaking), ban parking, or apply only at certain times. Always check the supplementary plate for precise details before deciding you cannot proceed.
