QUEBEC commercial driver’s licenses (CDLs) may not be verified in the Clearinghouse at this time due to system maintenance in Quebec. If this prevents an employer from conducting required pre-employment queries for information on QUEBEC 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.

The Clearinghouse is a secure online database that gives employers, the Federal Motor Carrier Safety Administration (FMCSA), State Driver Licensing Agencies (SDLAs), and State law enforcement personnel real-time information about commercial driver’s license (CDL) and commercial learner’s permit (CLP) holders’ drug and alcohol program violations.

The Clearinghouse contains records of violations of drug and alcohol prohibitions in 49 CFR Part 382, Subpart B, including positive drug or alcohol test results and test refusals. When a driver completes the return-to-duty (RTD) process and follow-up testing plan, this information is also recorded in the Clearinghouse.

Yes. When a violation is entered, the Clearinghouse associates it with a driver’s commercial driver’s license (CDL) information. This will be recorded even if the driver has not registered for the Clearinghouse. When an employer queries a driver’s information in the Clearinghouse (with the appropriate consent), they will enter the driver’s CDL information to verify if any violations are associated with that driver’s CDL.

A driver is required to enter their CDL information during their Clearinghouse registration. This allows them to view any violation or return-to-duty (RTD) information associated with their CDL.

No. The Clearinghouse contains only violations that occurred on or after January 6, 2020. If a driver’s violation occurred prior to January 6, 2020, and was in the return-to-duty (RTD) process when the Clearinghouse was implemented, the violation and any related RTD activity will not be entered into the Clearinghouse.

No, follow-up testing plans are not included in a driver’s Clearinghouse record. When a prospective employee has not completed a follow-up testing plan prescribed by the substance abuse professional (SAP), the subsequent new employer must obtain the follow-up testing plan from the previous employer, as required in § 382.413, and report the date the follow-up testing plan was completed.

  • Conduct limited queries at least annually for every driver they employ.
  • Request electronic consent from the driver for a full query, including pre-employment queries.
