Most commercial motor vehicles (CMVs) and their operators are subject to the U.S. DOT's Federal Motor Carrier Safety Regulations (FMCSRs), a large volume of rules aimed at keeping truck and bus operations safe. But what are CMVs? There are two distinct definitions in the FMCSRs, and mistaking one for the other could lead to serious fines and penalties.
The basic CMV definition is found in 49 CFR 390.5. This definition refers to a vehicle used on a highway, in interstate commerce, that:
Based on this definition, the operator of a relatively small truck, van, or bus used for a business-related purpose may need to comply with a majority of the FMCSRs.
Some of the areas of regulation include:
These regulations are found in 49 CFR parts 390 through 396 of the FMCSRs, which apply to operations involved in interstate commerce, meaning commerce that crosses state lines. If a CMV operator does not leave their home state and is not involved in interstate operations, they must comply with their state's (intrastate) CMV rules. Often states have a state-specific CMV definition, modified safety regulations, and/or exceptions not available to interstate carriers and drivers.
A different definition of "commercial motor vehicle" is used to determine if the driver needs a commercial driver's license (CDL) and drug and alcohol testing (these rules are found in parts 382 and 383).
Under this definition, a commercial motor vehicle (CMV) is a vehicle used in commerce (interstate or intrastate) to transport passengers or property when the motor vehicle is a:
This CMV definition, found in CFR 49 §383.5, speaks directly to drivers and motor carriers that operate large vehicles or certain specialized types of vehicles.
Understanding the CDL CMV definition is extremely important because drivers and motor carriers who operate these CMVs must comply with a host of other requirements, in addition to the FMCSRs in parts 390-396 including:
There are very few CMV exceptions. In both Parts 390 and 383, exceptions can be found for certain operations, including drivers of military vehicles and firefighters. See §§390.3 and 383.3 for complete details.
