Users may experience issues with verifying KENTUCKY commercial driver’s licenses (CDLs) in the Clearinghouse at this time. The Clearinghouse Team is aware of the issue and is working on resolving it. In the meantime, users may be able to successfully verify a CDL by entering the driver name in ALL CAPITAL LETTERS.

If this prevents an employer from conducting required pre-employment queries for information on KENTUCKY CDL- and CLP-holders only, the employer may hire a driver using solely the procedures set forth in 49 CFR 391.23(e), as outlined in the frequently asked questions.
