These signs warn drivers that an overhead structure (such as a bridge, garage entrance, pipe, or beam) is lower than standard height. They are critical for preventing collisions that damage both the vehicle and the structure, often saving costly repairs and preventing injuries. You can find these in our low clearance signs
Measure the lowest point and subtract a 3–6 inch safety margin. For custom measurements, use our clearance signs tool to print your specific height.
Place them on the obstruction and in advance of the hazard. For indoor warehouse beams, pairing them with caution floor signs at the approach can provide extra warning for forklift drivers.
This refers to a clearance bar hung on chains at the entrance to a parking structure. If a vehicle hits the bar (giving the driver a "headache"), they know they are too tall for the structure and must stop immediately before causing structural damage inside.
Yes, yellow is the MUTCD standard color for warning signs. The high contrast of black text on a yellow background ensures the height restriction is easily noticed by drivers in all lighting conditions, alerting them to the low clearance.
Warn before a forklift, truck or worker has an accident! Signs can precisely identify the clearance.
