Owners of a Tulsa, OK, trucking company say it will make lane departure warning technology standard equipment on their 1,000 trucks over the next three years.

According to a press release from Iteris Inc., the company that makes the system, Melton Truck Lines tried out the devices on 60 of its flatbed trucks during the past year.

The system is designed to detect if a truck is drifting out of its lane, and to sound an alert that sounds like you’re hitting a rumble strip.
