The C9 sign prohibits vehicles with a total height exceeding a specific limit, indicated on the sign itself. Its purpose is to prevent vehicles that are too tall from entering a road, tunnel, bridge, or other area where they could get stuck or cause damage.
If your vehicle's height, including any load, is greater than the measurement shown on the C9 sign, you must not enter the restricted area. You should immediately look for a safe place to stop, if necessary, and find an alternative, lawful route that accommodates your vehicle's height.
The C9 sign applies to any vehicle whose total height exceeds the specified limit. This includes cars with roof racks, vans, lorries, and buses. Always check your vehicle's exact height before proceeding if you are unsure.
Generally, no. The C9 sign indicates a strict prohibition. However, always pay attention to any additional panels placed beneath the C9 sign, as these might specify certain vehicle types or times when the restriction applies or does not apply. If no additional panel is present, the restriction applies to all vehicles exceeding the height limit.
A common trap is not considering the total height of the vehicle, including any load or roof-mounted equipment. Another trap is assuming the restriction is advisory; it is a mandatory prohibition. You must also be aware that this restriction continues until a 'End of Prohibition' sign is encountered or the restriction is otherwise lifted.
