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

The primary purpose of a Commercial Driver's License (CDL) is to certify that drivers can safely operate large and potentially hazardous vehicles. This includes a range of vehicles, such as buses, trucks, and other commercial vehicles that carry passengers or haul cargo. The CDL process ensures that drivers have met specific training and testing requirements that demonstrate their ability to handle these larger, more complex vehicles safely.

Obtaining a CDL involves comprehensive knowledge of vehicle operation, safety regulations, and the unique challenges presented by driving larger vehicles. This certification is crucial for maintaining road safety, ensuring that only qualified individuals operate these vehicles, which can pose greater risks to both drivers and other road users.

The focus on safety and skill in operating large vehicles underscores the significance of the CDL, making the correct answer clear in terms of its role in promoting safe driving practices within the commercial sector.
