No motor vehicles except solo motorcycles
Prohibitory and restriction signs

No motor vehicles except solo motorcycles

Cars and other multi-track motor vehicles are prohibited, but solo motorcycles may enter.

Cars and other motor vehicles covered by the restriction must not enter. The exception is for solo motorcycles, meaning motorcycles without a sidecar.

The common design shows a black car inside a red-bordered white circle. Poland's B-3 and Germany's 251 use this design without a diagonal bar or a motorcycle symbol.

How it looks in each country

Official sign in each country; the code is its number in the national rules. Signs that come in two directions show the left and the right version.
