Overheight Warning Solutions

Overheight Warning System


The Overheight Warning System delivers our clients with the best chance of avoiding potential low structure collisions.

Our solution can greatly reduce the number of collisions with your low-lying bridge.

Infrared Sensor Detection

Infrared transmitter and receiver sensors are mounted on either side of the road in advance of the low structure, creating an infrared beam over the road. When an overheight vehicle breaks the infrared beam, the receiver sends a wireless signal to active the warning alert, notifying the driver that their vehicle won’t clear the structure ahead.

LED-Enhanced Warning Alerts

Overheight Warning Systems can be designed with a variety of MUTCD-compliant, LED-enhanced BlinkerSign® or BlinkerBeacon™ warning alerts dependent upon customer preference and environmental factors. Mounting options can also be tailored to meet each installation need. 

Optional BlinkLink Programming

Remotely monitor the status of TAPCO Overheight Warning Systems with BlinkLink® cloud software. Connected via an optional cellular modem, BlinkLink® cameras capture overheight vehicle images upon system activation and send email and text alerts to predetermined recipients.
