What defines a "commercial driver's license"?

A commercial driver's license (CDL) is specifically established for individuals who operate commercial motor vehicles (CMVs). This includes large trucks, buses, and vehicles that transport hazardous materials or a certain number of passengers. The regulations governing CDLs ensure that drivers of these vehicles meet specific standards of knowledge and skill due to the complexities and potential dangers associated with operating heavy and transport vehicles.

The purpose of the CDL is to ensure safety on the roads by requiring drivers to undergo specialized training and testing that focuses on the unique challenges of maneuvering larger vehicles. By having a distinct license dedicated to these drivers, regulatory agencies can better monitor and enforce the standards necessary for safe commercial driving.
