43. Length limit

A length limit is a restriction that prohibits vehicles or vehicle combinations longer than a specified maximum length from entering a road or area. The stated length normally includes the complete vehicle combination and any load where national rules specify this.

Length restrictions are commonly used where long vehicles cannot safely negotiate narrow streets, tight bends, bridges, tunnels or other constrained road layouts. Drivers whose vehicle exceeds the indicated limit must use another permitted route.

What does a vehicle length limit mean?

A length limit indicates the maximum vehicle or vehicle-combination length permitted beyond the restriction. Vehicles exceeding the displayed value may not proceed.

Does a length limit include a trailer?

Normally the relevant measurement applies to the complete vehicle or vehicle combination covered by the sign. National rules determine precisely how trailers and projecting loads are included.

Why are vehicle length limits used?

They are used where long vehicles could have difficulty negotiating the road safely, such as on narrow streets, tight bends, constrained junctions or other locations with limited manoeuvring space.
