ITD installing sensors at Idaho Ports of Entry to find damaged tires

A tire blowout on a semitruck traveling at highway speeds can be dangerous, even deadly. As part of the Idaho Transportation Department’s (ITD) ongoing commitment to safety, the agency will begin installing Tire Anomaly and Classification (TAC) Systems at Ports of Entry (POE) around the state.

Ports of Entry inspect commercial vehicles and oversee their safe operation on Idaho roads. TAC systems are installed in the road and screen semitruck tires for anomalies and damage. Port employees can use the TAC data to notify truck drivers of damaged or underinflated tires before they cause a safety problem.

Idaho’s first TAC system was installed at the Declo POE in February 2023. Over 1,100 tire anomalies have been detected since the system went live.

“Installing TAC systems is a proactive approach to safety,” explained ITD Commercial Vehicle Services Manager Craig Roberts. “The driving public is much safer when commercial vehicles with tire issues are stopped to correct blowouts, flats, or missing tires.”

The TAC installation schedule is as follows:

  • East Boise POE in both directions, week of May 28.
  • Lewiston POE in both directions, week of July 15.
  • Sage POE in both directions, tentatively late July or early August depending on other road construction in the area.
  • Huetter POE in both directions, tentatively August depending on other road construction in the area.
  • Inkom POE will have a phased installation. Southbound is to be completed in June. Northbound is to be completed next year during work on the Inkom interchange.

The cost for all the new TAC systems combined is $1.2 million. In 2022, the economic cost of crashes involving commercial motor vehicles in Idaho was over $627 million.
