CDL Downgrade Warning - 163,000 Truck Drivers Must Act by November 18
CDL Downgrade Warning: starting November 18, 2024, State Driver’s Licensing Agencies will revoke CDLs for drivers with unresolved violations.

The Federal Motor Carrier Safety Administration (FMCSA) has set a critical deadline for commercial truck drivers holding a “prohibited” status in the FMCSA Drug & Alcohol Clearinghouse. Starting November 18, 2024, State Driver’s Licensing Agencies (SDLAs) will revoke commercial driving privileges for drivers facing a CDL Downgrade Warning. With over 163,000 CDL and CLP holders currently holding a “prohibited” status, it’s vital to understand the impact of this deadline and how to address it.
Understanding the FMCSA Drug & Alcohol Clearinghouse
The FMCSA Drug & Alcohol Clearinghouse is an online database that tracks violations of the drug and alcohol testing program. It was established to provide employers, law enforcement, and SDLAs with real-time access to driver records related to:
- Positive substance use tests
- Refusals to test
- Other drug and alcohol program violations
Registrations Overview
Since registration began on September 28, 2019:
- CDL/CLP holders, employers, MROs, SAPs, and C/TPAs are all required to register.
- As of February 2024, thousands of drivers and organizations are now registered.
Query Types and Trends
Employers must query the Clearinghouse:
- Pre-Employment Queries: When hiring new drivers
- Annual Queries: For current employees
Query Statistics:
- Total queries conducted since January 2020 have grown significantly.
- Full queries (including those elevated from limited queries) represent a substantial portion of the overall queries.
Violations and Return-to-Duty (RTD) Process
Types of Violations:
- Controlled Substance (Drug) Violations: Positive drug tests, refusal to test
- Alcohol Violations: Positive alcohol tests, refusal to test
Violation Trends:
- Over 261,425 test results with violations have been reported to the Clearinghouse since January 2020.
- Marijuana metabolites account for 81% of the violations, with cocaine and methamphetamine also being significant contributors.
Return-to-Duty (RTD) Process
The RTD process is critical for CDL/CLP holders to restore their driving privileges. Key steps include:
- Initial SAP Assessment: Drivers must undergo an evaluation by a Substance Abuse Professional (SAP).
- Education/Treatment Plan: Based on the assessment, the SAP develops an education/treatment plan.
- Follow-Up Testing Plan: After completing treatment, the SAP establishes a follow-up testing plan.
- RTD Test with Negative Result: Once the RTD test is passed, drivers are eligible to return to safety-sensitive functions.
Upcoming CDL Downgrade Warning Rules
The second Final Rule (Clearinghouse-II) issued by FMCSA in October 2021 requires SDLAs to:
- Revoke commercial driving privileges for drivers with “prohibited” status.
- Downgrade licenses until the driver completes the RTD process.
What This Means for Truck Drivers
If you hold a “prohibited” status due to a drug or alcohol violation:
- Act Quickly: Begin the RTD process immediately.
- SAP Assessment: Schedule and complete an initial assessment with a Substance Abuse Professional.
- Complete Treatment: Follow the SAP’s recommended education/treatment plan.
- Negative RTD Test: Pass the RTD test to regain eligibility.
With the November 18, 2024, deadline approaching, drivers facing a CDL Downgrade Warning must start the RTD process immediately to prevent license downgrades. Employers should actively use the Clearinghouse to ensure compliance and maintain a safe workforce. As a vital tool for improving road safety, the FMCSA Clearinghouse provides transparency and accountability, benefiting the entire trucking industry.
