Renewing your Commercial Driver’s License (CDL) in South Carolina is a straightforward process but it does require a bit more preparation than a regular driver’s license. Because CDL holders are subject to federal and state regulations, you’ll need to meet specific medical and documentation requirements – official site

In South Carolina, CDL licenses typically expire on your birthday. You can renew:

• Up to 6 months before expiration
• After expiration (with possible late penalties or restrictions)

Before visiting the South Carolina Law Enforcement Agency office, make sure you bring the following documents:

• Your current CDL license
• Proof of identity (if requested)
• Proof of South Carolina residency (if requested)
• Payment for renewal fees

Most CDL holders must maintain a Department of Transportation (DOT) medical card. You’ll need to:

• Pass a physical exam with a certified medical examiner
• Submit your updated medical certificate to the South Carolina DMV

If you fail to maintain your medical certification, you can lose your commercial driving privileges — even if your license itself hasn’t expired.

In addition to standard CDL renewal requirements, South Carolina also verifies your legal presence and immigration status in the United States during the renewal process.

In addition to standard CDL renewal requirements, Wyoming also verifies your legal presence and immigration status in the United States during the renewal process.

Depending on your immigration status, you may be required to provide documents proving lawful presence in the United States when applying for or renewing your CDL. Acceptable documents may include:

• U.S. passport or U.S. birth certificate
• Permanent Resident Card (Green Card)

Please note that all documents must be current and valid at the time of application.
