What is the minimum age requirement to apply for a Commercial Driver's License (CDL) in South Carolina?

To apply for a Commercial Driver's License (CDL) in South Carolina, the minimum age is 18 years old. This requirement is in place to ensure that applicants have reached a level of maturity and responsibility that is necessary for operating commercial vehicles, which can be significantly larger and more complex than standard vehicles.

At 18, individuals can begin to drive intrastate (within South Carolina) in non-commercial trucking jobs, but they are restricted from engaging in interstate commerce or transporting hazardous materials until they turn 21. This two-tiered age system reflects the understanding that driving a commercial vehicle comes with increased risks and responsibilities, particularly when operating across state lines or handling dangerous goods. Thus, while individuals can apply for their CDL at 18, some of the privileges associated with the license are not available until they reach the age of 21.
