Clearinghouse users currently cannot verify driver commercial driver's license (CDL) information. The Clearinghouse Team is aware of the issue and currently working to resolve it. If this prevents an employer from conducting required pre-employment queries, 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.
