What does the abbreviation CDL stand for in the context of driving regulations?

The abbreviation CDL stands for Commercial Driver License. This term is pivotal in the context of driving regulations because it designates a specialized license required for operating large or commercial vehicles, such as buses and trucks that exceed a certain weight threshold. Holding a CDL ensures that the driver has received specific training and meets the regulatory requirements necessary to safely operate these larger vehicles, which can pose greater risks than standard passenger vehicles due to their size and weight.

The CDL is governed by both state and federal regulations, ensuring uniform standards for driver training and safety across different jurisdictions. This license is essential for maintaining road safety and ensuring that drivers are capable of handling the complexities associated with operating commercial vehicles, including understanding the specific traffic laws, vehicle maintenance requirements, and safety protocols.
