Warning Signs
Low Clearance Sign
An overhead structure has limited clearance. The measurement shows the available height.
What to Do
Know the full height of your vehicle and load before proceeding under the structure.
A Detail to Remember
The illustrated 3 m is an example, not a standard bridge height. Roof-mounted equipment also counts towards vehicle height.
Understanding Warning Signs
Yellow warning signs ask you to anticipate a condition ahead. Read any distance or speed plaque with the main symbol, then adjust to what you can actually see on the road.
