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. Since November 18, 2024, every State must downgrade a CLP or CDL when FMCSA notifies it that the driver is in Clearinghouse "prohibited" status; the downgrade must be completed and recorded on the CDLIS record within 60 days of the State's receipt of the notice (49 CFR 383.73(q)). Lag in CDLIS update is the most common cause of stale data on a pulled MVR.
