Freight & NCPass

The N.C. Department of Transportation's transponder system, NCPass, helps monitor the weight and safety compliance of commercial trucks on North Carolina's highways.

Since 2007, the voluntary program has allowed compliant motor carriers with up-to-date credentials to bypass North Carolina's weigh stations, resulting in numerous benefits, including:
  • Better oversight and enforcement of motor carrier compliance
  • Reduced back-ups at weigh stations
  • More efficient travel time for trucks, particularly those authorized to bypass stations
  • Increased highway safety
  • Reduced fuel consumption and noxious emissions

How NCPass Works

Motor carriers enrolled in NCPass have a good compliance history and safety record and are authorized to bypass weigh stations in North Carolina.

As a truck with an NCPass transponder approaches a weigh station, a roadside reader detects the transponder and alerts the driver if the truck is authorized to bypass the station. At the same time, the weigh station is alerted with an image of the truck, along with its identification information.

The transponder will also alert the driver if they are not cleared to bypass a weigh station.


Enrollment in NCPass is available to trucking companies for an annual fee. Any trucking company can apply for the program at the NCPass website.  

The program is operated and maintained by International Road Dynamics Inc.
