Maximum length
Prohibitory and restriction signs

Maximum length

Vehicles longer than the length shown must not pass.

Check the full length of the vehicle or vehicle combination. Include any trailers when checking a combination against the limit.

A common design is a red-bordered circle with a vehicle silhouette and a length figure. Poland uses B-17, France B10a and Germany 266.

How it looks in each country
