Mainline E-Screening Systems

Commercial Vehicle Enforcement

IRD's Mainline Electronic Screening (E-Screening) systems screen commercial vehicles on the mainline highway upstream from a weight enforcement station.

Vehicles are screened and tracked as they pass over the Sorter System sensors. Vehicles that are potentially in violation of regulations and credentials will be signaled to exit to the inspection station ramp; vehicles that are in compliance will be signaled to bypass the station.

  • Efficiency; only potential violations of regulations, credentials and safety are flagged to exit to the weigh station
  • Reduced vehicle emissions, congestion, delay
  • Reduced weigh station real estate
  • Enhanced safety
