Weight Enforcement Program

Many motor carrier enforcement professionals weigh commercial vehicles during inspections to help protect our transportation infrastructure. Using weigh-in-motion and portable scales, commercial vehicles are checked for compliance with Pennsylvania’s weight laws. Motor carrier height and weight restrictions can be found in the Pennsylvania Truckers Handbook.
