On Monday, July 20, 2026, from 8:00 PM to 9:00 PM ET, Clearinghouse users will not be able to verify driver CDL information due to FMCSA system maintenance. The maintenance is expected to be completed by 9:00 PM ET on Monday, July 20, 2026.
Additionally, users may experience issues verifying ARIZONA commercial driver’s licenses (CDLs) in the Clearinghouse at this time due to system maintenance in Arizona. If this prevents an employer from conducting required pre-employment queries for information on ARIZONA 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.
