What is the main purpose of a Commercial Driver's License (CDL)?

The main purpose of a Commercial Driver's License (CDL) is to ensure the safe operation of heavy vehicles, which often includes trucks and buses that require specialized knowledge and skills to operate safely on public roads. CDLs are regulated at both the federal and state levels to ensure that drivers meet specific training and testing requirements, thus promoting public safety.

Heavy vehicles can pose significant risks due to their size and weight, which affect their handling, braking distance, and visibility compared to standard passenger vehicles. By requiring a CDL for drivers of these vehicles, the licensing process helps ensure that operators are adequately trained in vehicle operation, safe driving practices, and the rules of the road. This enhances the safety of all road users, including those in smaller vehicles.

The other options relate to different aspects of vehicle use but do not accurately reflect the primary role of a CDL. For instance, while operating passenger vehicles may be a component of driving, it does not encompass the commercial focus of the CDL. Providing insurance is unrelated to the licensing process itself, and recreational vehicle use is not the primary intent of the CDL, which is specifically for commercial driving purposes.
