Recently there has been much talk and “traffic” about hours of service regulations for 18 Wheelers. Hours of service regulations define how much a driver can drive during certain periods of time and apply to Commercial Motor Vehicles. An important first question is what qualifies as a Commercial Motor Vehicle for purposes of the Federal Motor Carrier Safety Regulations Hour of Service Rules. 18 Wheelers typically do of course, but other vehicles qualify also. The Federal Motor Carrier Safety Administration defines Commercial Motor Vehicle on its website as in general “a vehicle that is used as part of a business and is involved in interstate commerce and weighs more than 10,001 pounds.” There are other vehicles that can qualify as a CMV including, but not limited to, any vehicle carrying hazardous material in quantities requiring placards, any vehicle designed or used to transport 9 or more passengers for compensation, or any vehicle designed or used to transport 16 or more passengers not for compensation.
