Effectiveness of Weigh Station Pre-Clearance/E-Screening Systems


To research available weigh station pre-clearance/e-screening systems to determine their effectiveness related to roadside enforcement efforts, commercial vehicle safety, crash reduction, injuries avoided, and lives saved.


The Innovative Technology Deployment (ITD) Grant Program allows States to purchase, install, and maintain pre-clearance/e-screening systems to help them manage commercial vehicle traffic for the purposes of roadside inspection selection.


The research team will identify and research the most prevalent weigh station pre-clearance/e-screening systems; conduct a side-by-side analysis of screening information made available to States; perform a roadside analysis on usage of systems by enforcement personnel; complete an inspection analysis of carriers that would have been cleared versus carriers without pre-clearance systems onboard; assess the benefits of pre-clearance/e-screening systems to industry; and determine crashes prevented, injuries avoided, and lives saved due to the use of e-screening systems.
