What must over-height vehicles display for safety?

Over-height vehicles must display their height in metres, visible to the operator, for safety reasons. This requirement ensures that operators are aware of the vehicle's dimensions, which is crucial for preventing accidents or damage when navigating through areas with height restrictions, such as underpasses or low bridges. The clear display of height in metres allows for immediate recognition, helping both the operator and other road users to make informed decisions about movement in confined or elevated spaces.

Having this information prominently displayed increases safety for all involved by reducing the risk of collisions that can occur when a vehicle exceeds vertical clearance limits. The requirement for height in metres specifically aligns with safety protocols that emphasize accurate measurements, as different regions may have varying standards for unit measurements, but consistency in metres enhances communication and compliance among drivers.
