To help drivers of commercial motor vehicles (CMVs) remain safe and keep trucking businesses in compliance with the Federal Motor Carrier Safety Regulations and Hazardous Materials Regulations, the Federal Motor Carrier Safety Administration records the number of violations discovered through roadside inspections conducted by Motor Carrier Safety Assistance Program inspectors.
If an inspection results in a serious violation, an out-of-service (OOS) order is issued. The violation must be corrected before the driver or vehicle can return to service.
