The Commercial Driver’s License Information System (CDLIS) is a nationwide computer system that enables state driver licensing agencies (SDLAs) to ensure that each commercial driver has only one driver’s license and one complete driver record. State driver licensing agencies use CDLIS to complete various procedures, including:
- Transmitting out-of-state convictions and withdrawals
- Transferring the driver record when a commercial driver’s license holder moves to another state
- Responding to requests for driver status and history
CDLIS was established under the Commercial Motor Vehicle Safety Act (CMVSA) of 1986 and is based on the Federal Motor Carrier Safety Regulations (FMCSRs) in 49 CFR 383 and 384.
