Maximum height
Prohibitory and restriction signs

Maximum height

Vehicles taller than the height shown must not pass.

Check the vehicle’s full height, including its load and roof equipment. Signs may appear before a low bridge or tunnel and on the structure itself.

A common regulatory design is a red-bordered circle showing the height between vertical arrows. The UK’s 629.2A shows metric and imperial measurements. The US W12-2a is a yellow rectangular clearance warning sign used on the structure.

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.
