USDOT Number Reader
High-speed Mainline
Low-speed Weigh Stations

Get real-time automated intelligence to accelerate throughput, enforce compliance, and ensure safety.

The Perceptics USDOT Number Reader captures the USDOT, VIN and Motor Carrier numbers on commercial vehicles, day and night, with industry-leading accuracy. Perceptics USDOT Number Readers have processed millions of images of commercial vehicles from all U.S. and Mexican states and Canadian provinces. The system can stand alone or be easily integrated with all current WIM technology.

When paired with the Perceptics License Plate Reader or Hazmat Placard Reader software, officials have multiple vehicle datapoints with which to make quick and informed decisions. 

Product Hightlights

  • Accuracy of 90% on over 80% of commercial vehicles
