Effective January 30, 2012, federal regulations require all commercial driver's license and beginner permit holders and new applicants to self-certify the type of commerce for which they intend to operate. They must also provide medical certification for any type of commerce that requires it. To self-certify, drivers must complete Form DL-405A.
SCDMV will collect the driver’s certification information and add it to the national Commercial Driver License Information System (CDLIS) record. All commercial driver's license holders, beginner permit holders and new applicants must self-certify by January 30, 2014 or risk losing his or her commercial credential. Commercial drivers and beginner permit holders must comply each time they apply for a new credential, renew or upgrade their credential.
