What driver conduct is prohibited?
  • CMV drivers are held to a higher standard regarding drug and alcohol use than the average motorist.

The average semi-truck weighs between 40,000 and 80,000 pounds when fully loaded. The force behind these large trucks does not allow drivers much of a margin for error when reacting to other motorists and hazards on the roadways. Drivers needs to be sharp and alert, and any impairment due to drugs or alcohol may increase the likelihood of a crash.

The Federal Motor Carrier Safety Administration (FMCSA) is charged with reducing the number of commercial motor vehicle (CMV) crashes on U.S. highways. As a part of fulfilling its mission, the agency holds drivers operating CMVs requiring a commercial driver’s license (CDL) to a higher standard with regard to drug and alcohol use than the average motorist. Drivers that engage in prohibited behaviors cannot be allowed to operate a CMV until the employees go through the Department of Transportation’s return-to-duty procedures.
