Every motor carrier regulated by the U.S. DOT needs to apply a set of principles, framework, processes and measures to prevent accidents, injuries and other adverse consequences that may be caused by unsafe commercial drivers or unsafe commercial motor vehicles (CMV).
Safety audits aim to see whether a passenger carrier understands safety regulations and has basic safety management controls in place. Roadside inspections are essential for assessing whether motor carriers are following safety rules. States have the primary responsibility for roadside inspections of commercial vehicle driver logbooks, driver qualifications, and vehicle condition for motor carriers.
