This sign means that any vehicle longer than the measurement shown on the sign or a supplementary plate is not allowed to proceed past this point. It's a prohibition, not a suggestion, and applies to vehicles based on their overall length.
You must check your vehicle's length against the measurement indicated. If your vehicle exceeds this length, you must not proceed past the sign or into the restricted area. You will need to find an alternative route.
Exceptions may be indicated on supplementary plates attached to the sign. These could specify certain times, vehicle types, or purposes for which the length restriction does not apply. Always read any supplementary plates carefully before deciding if an exception is relevant to you.
A common mistake is assuming the sign only applies if you can physically see a problem, or that other drivers ignoring it means it's okay to do so. Remember, this is a legal prohibition. Another trap is not checking for supplementary plates that might offer an exemption or provide the exact length limit.
The sign specifically prohibits vehicles exceeding the indicated length. While it doesn't explicitly name vehicle types, in practice, it's most relevant for longer vehicles like lorries, coaches, or sometimes long vans and cars towing trailers. Always ensure your specific vehicle and load configuration are compliant.
This sign specifically uses imperial measurements (e.g., feet). Other signs might use metric (metres). It's crucial to know your vehicle's dimensions in the unit specified by the sign to correctly interpret the restriction and avoid potential violations or hazards.
