Tennessee to add Weigh-In-Motion tech at nearly 30 sites statewide

New Weigh-In-Motion technology is coming to dozens of interstate and state routes in Tennessee within the next year.

The Tennessee Department of Transportation (TDOT) recently awarded a contract to tolling and enforcement solutions company Quarterhill Inc. to install Weigh-In-Motion (“WIM”) systems at 28 sites on interstates and state routes across Tennessee.

The installation of the WIM systems is expected to be completed by May 2025, according to a news release from Quarterhill.

Some of the WIM systems will be integrated into existing Tennessee Highway Patrol enforcement sites so that troopers can integrate WIM data into their commercial vehicle inspection programs.

Quarterhill shared insights into what data will be collected by the WIM systems:

“The WIM systems will capture and record axle weights and gross vehicle weights as vehicles drive over the measurement sites at highway speeds … In addition to collecting data, the WIM systems will be able to determine if trucks are overloaded so they can be routed to inspection stations for ticketing, thus cutting down on excessive highway wear-and-tear and the number of unsafe vehicles on the road. There is also the potential for future upgrades of the sites with E-screening technology to automate the evaluation of driver and trucking company safety ratings, resulting in enhanced enforcement capabilities and further improvements to highway safety.“

“We are pleased to collaborate with TDOT on this project to elevate highway safety and efficiency in Tennessee,” said Chuck Myers, CEO of Quarterhill. “The deployment of advanced WIM systems will provide vital data to facilitate effective enforcement, enhance asset management, and significantly improve the safety of Tennessee’s highways. This project is our first major initiative in Tennessee, and we look forward to exploring opportunities to expand our footprint further in the State.”
