The Commercial Vehicle Safety Division (CVSD) coordinates the Federal Motor Carrier Safety Assistance Program (MCSAP) throughout Pennsylvania using a strategy of education, regulatory oversight, and enforcement to prevent crashes and save lives. In addition, the CVSD is responsible for coordinating Pennsylvania’s vehicle weight enforcement and school bus safety programs.

Motor Carrier Safety Assistance Program
Throughout Pennsylvania, more than 700 specially trained state and local officers inspect commercial vehicles and their drivers for compliance with state and federal motor carrier safety regulations. Inspections are conducted at interstate weigh stations as well as along many of the state’s frequently travelled rural roadways.
