This supplementary plate specifies that the rule on the sign above is restricted to vehicles whose total weight exceeds the value shown. It is used to target heavier vehicles, such as trucks, buses, or loaded combinations, depending on the context. Drivers must interpret the weight as the vehicle’s total weight, not just cargo weight. If your vehicle’s total weight is above the threshold, you must follow the main sign’s instruction. If it is at or below the threshold, the main sign does not apply to you unless other rules are present.

The T5 sign is a supplementary plate that works with a main traffic sign. It means the rule on the sign above is only for vehicles whose total weight is greater than the number shown on the T5 plate. For example, if a speed limit sign is placed above a T5 sign showing '10', then the speed limit only applies to vehicles over 10 tonnes total weight.
You need to know your vehicle's total weight (also called gross vehicle weight). If your vehicle's total weight is more than the weight indicated on the T5 plate, then the main sign's instruction applies to you. If your vehicle's total weight is at or below the stated weight, the main sign does not apply.
The T5 sign refers to the vehicle's 'total weight', which is the combined weight of the vehicle itself and its maximum possible load. It is not just the weight of the cargo you are currently carrying. You must check your vehicle's classification for its maximum permitted total weight.
A common mistake is assuming the weight refers only to the load or cargo. Another is forgetting to check your vehicle's total weight rating, especially if you are close to the threshold. Always confirm your vehicle's total weight classification to be sure whether the main sign's restriction applies to you.
Yes, the T5 sign specifically targets heavier vehicles by indicating that the main sign's rule applies only to them. If your vehicle's total weight exceeds the threshold, you must comply with the primary sign. Drivers of lighter vehicles are typically exempt from that specific instruction.
