Analysis of historical data collected by Kentucky State Police – Commercial Vehicle Enforcement (KSP-CVE) for 2017-2021 revealed that CMV drivers were charged with illegally bypassing weigh stations 2,616 times. Drivers were charged with an average of two other violations when cited for illegal bypassing — most often violations related to credentialing, vehicle safety, or driver safety. Site visits to three permanent weigh stations in Kentucky revealed that CMVs regularly bypass weigh stations illegally, including those authorized to use preclearance systems (Drivewyze and PrePass).

Evaluation Of Manual Infrared Brake Screening Technologies, Joseph Crabtree, Brian Beaven, Jennifer Walton

Kentucky Transportation Center Research Report

The purpose of this project was to install and operate two manual infrared (IR) brake screening systems at Kentucky inspection facilities to enhance the quality of Level 1 safety inspections. A radio button in the inspection software allowed enforcement personnel to indicate when the IR equipment was used to select a truck for inspection. This feature allowed a direct comparison of performance measures (e.g., number of violations identified per inspection, out-of-service rate, etc.) for IR-generated inspections versus all inspections.

The evaluation focused on inspections at the Lyon County site for a 60-day period during September and October 2021. Analysis of …
