Hazardous Materials (HM) - Roadside Inspections

   

Roadside Inspections are examinations of commercial motor vehicles and/or drivers by Motor Carrier Safety Assistance Program (MCSAP) Inspectors.

MCSAP Inspectors conduct roadside inspections on commercial motor vehicles and drivers to check that they are in compliance with the Federal Motor Carrier Safety Regulations (FMCSRs) and Hazardous Materials Regulations (HMRs). If an inspection results in serious violations, the driver will be issued a driver or vehicle Out-of-Service Order. These violations must be corrected before the driver or vehicle can return to service.

This module gives data for five fiscal or calendar years of roadside inspections conducted on motor carriers that transport hazardous materials in interstate or intrastate commerce.
