CDLIS Update

Definition

A CDLIS update is the AAMVA-administered transmission of a CDL holder's licensing event - issuance, renewal, suspension, revocation, downgrade, or self-certification change - across the multi-state CDLIS network. Federal regulation 49 CFR §384.105 requires every state to send updates within 10 days of the event. Carriers see the downstream effect when running a state MVR - the report reflects CDLIS data even if the driver licensed in a different state. CDLIS-II integration (rolled out 2023-2025) added near-real-time transmission of Clearinghouse "prohibited" status, which now triggers automatic state-side downgrade in participating jurisdictions. Lag in CDLIS update is the most common cause of stale data on a pulled MVR.
