The FMCSA Drug and Alcohol Clearinghouse has been through two significant rule changes since it launched in January 2020. If your process for hiring and monitoring CDL drivers has not been updated to reflect both, your operation has a compliance gap.
Pre-Employment Queries: What Changed in January 2023
Before January 6, 2023, employers hiring CDL drivers had to conduct both an electronic Clearinghouse query and direct manual inquiries with previous employers to cover the required three-year lookback for drug and alcohol violations under 49 CFR 391.23(e) and 382.413(a).
Beginning January 6, 2023, the Clearinghouse had accumulated three full years of violation data. At that point, a pre-employment Clearinghouse query alone satisfies the inquiry requirement for FMCSA-regulated employment history, as set forth in 49 CFR 382.701(a), 382.413(b), and 391.23(e)(4).
One exception remains. If a prospective driver was employed by an employer regulated by a DOT agency other than FMCSA during that three-year window (Federal Railroad Administration, Federal Transit Administration, Federal Aviation Administration, or similar), you must still request drug and alcohol violation information directly from those employers. That history is not reported to the Clearinghouse.
Annual Query Requirements Have Not Changed
Employers must query the Clearinghouse at least once every 12 months for each CDL driver currently employed, per 49 CFR 382.701(b). This runs on a rolling basis from the date of the last query, not a calendar year.
Before conducting a limited query on an existing driver, you must have a signed general consent form on file. A sample limited query consent form is available at clearinghouse.fmcsa.dot.gov.
If you are unsure when your last round of annual queries was completed, log into the Clearinghouse and check your Query History page.
Clearinghouse II: CDL Downgrades Began November 2024
The second Clearinghouse final rule (Clearinghouse II) took effect November 18, 2024, and added a consequential new layer for employers managing CDL drivers.
Under Clearinghouse II, State Driver Licensing Agencies (SDLAs) are now required to remove commercial driving privileges from any driver who holds a “prohibited” status in the Clearinghouse. That means a driver’s CDL or commercial learner’s permit (CLP) will be downgraded, and they will be ineligible to operate a commercial motor vehicle until they complete the return-to-duty (RTD) process under 49 CFR Part 40, Subpart O.
For employers, this has a direct operational impact. A driver who was previously prohibited but still physically held a valid CDL card can no longer fly under the radar. SDLAs are actively checking the Clearinghouse and initiating downgrades. As of late 2024, over 250,000 CDL drivers had been reported to the Clearinghouse for a drug or alcohol violation.
If a driver on your roster is in prohibited status and has not completed RTD, their license will be downgraded. You cannot legally allow them to operate a CMV. FMCSA’s Return-to-Duty Quick Reference Guide outlines the steps drivers must complete to have their status updated to “not prohibited” and their commercial privileges reinstated.
