What Is the CDL Downgrade Rule for Drivers in Prohibited Clearinghouse Status?

Since November 18, 2024, a driver's status in the FMCSA Drug and Alcohol Clearinghouse can affect the driver's license itself, not just the right to drive for a carrier. FMCSA rules now require State Driver Licensing Agencies to act on "prohibited" status.

What "prohibited" means. A driver who has engaged in conduct prohibited by Part 382 Subpart B, such as a verified positive drug test, an alcohol result of 0.04 or higher, or a refusal, may not perform safety-sensitive functions, and no employer may permit it (49 CFR 382.501(a)). The prohibited conduct rules list these violations. The driver stays prohibited until the return-to-duty process in Part 40 Subpart O is met (49 CFR 382.503(a)).

The downgrade. When FMCSA notifies a State that a CLP or CDL holder is prohibited, the State starts its downgrade procedures. The downgrade must be completed and recorded on the CDLIS driver record within 60 days of the State's receipt of the notice (49 CFR 383.73(q)). In this rule, "downgrade" means the State removes the CLP or CDL privilege from the driver's license (49 CFR 383.5, definition of CDL downgrade, paragraph (4)). The driver may still hold a base license to drive a car, but not the commercial privilege. States must comply under 49 CFR 384.235.

Stopping or reversing the downgrade.

• Before the downgrade is completed. If FMCSA notifies the State that the driver is no longer prohibited, the State ends the process without removing the privilege, if State law permits (49 CFR 383.73(q)(1)).
• After the downgrade is recorded. Once the driver completes the return-to-duty steps and FMCSA notifies the State, the State makes the driver eligible for reinstatement, if State law permits (49 CFR 383.73(q)(2)).
• When the prohibited status was an error. The State reinstates the privilege as quickly as possible and removes references to the erroneous status from the CDLIS record and the motor vehicle record (49 CFR 383.73(q)(3)).

Driving after a downgrade. A driver whose commercial privilege was removed may not drive a commercial motor vehicle until the State reinstates it (49 CFR 382.503(b)). Finishing the SAP and return-to-duty process makes the driver eligible, but the license step is separate.

Licensing checks. States also query the Clearinghouse before issuing, transferring, renewing or upgrading a CLP or CDL. They may not issue the credential to a driver shown as prohibited (49 CFR 383.73(a)(8) for a CLP, (b)(10) for an initial CDL, (c)(10) for a transfer, (d)(9) for a renewal, (e)(8) for an upgrade and (f)(4) for a non-domiciled CDL).

A note on 49 CFR 383.51. Section 383.51 covers disqualifications for listed offenses, such as violating an out-of-service order. The Clearinghouse downgrade is a separate process under 383.73(q), not a disqualification.
