South Carolina CDL Requirements

Age Requirements for South Carolina CDL

South Carolina follows federal age standards for commercial driver's licenses:

• 18 years old: Minimum age for Commercial Driver Instruction Permit (CDIP/CLP) or CDL for intrastate operation only
• Under 21 restrictions: Cannot operate commercially across state lines or transport hazardous materials
• 21 years old: Required for interstate commercial operation and hazardous materials transport

These age requirements apply to all Class A, Class B, and Class C commercial driver's licenses. The classification differences relate to vehicle weight and type, not age requirements.
