A vehicle weighing 10,001 pounds or more is classified as a commercial motor vehicle (CMV), which subject to specific regulations to ensure safe operation. One key requirement for such vehicles is adherence to hours-of-service regulations. These regulations are designed to prevent driver fatigue by limiting the number of hours a driver can operate a CMV within a specific period, as well as requiring regular rest breaks.

This is essential to maintain safety on the roads, as operating a heavy vehicle can increase the risk of accidents if the driver is fatigued. Other options, while relevant in certain contexts, do not apply universally to all vehicles above this weight threshold. For example, a special license plate or insurance requirements may vary by state and are not specific to the weight of the vehicle, and a passenger vehicle endorsement is specifically related to vehicles designed to transport passengers, not just those over 10,001 pounds.
