CDLIS

Also known as: Commercial Driver's License Information System

By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team

Definition

CDLIS is the AAMVA-administered information system that links every state's commercial-driver licensing database. When a state issues, suspends, or revokes a CDL, the action is reported to CDLIS and visible to all other states. Carriers cannot pull CDLIS reports directly; the state DMV uses CDLIS to verify a driver's status during licensing transactions. Federal regulation 49 CFR §384.105 requires every state to participate. The CDLIS network prevents a CDL holder from holding licenses in multiple states or from licensing-shopping after a disqualification. Any pre-employment MVR pulled from a state DMV implicitly reflects CDLIS data.
