What to Do When Clearinghouse Shows Prohibited and California Downgrades a CDL

A driver whose Drug & Alcohol Clearinghouse status is Prohibited may not perform DOT-regulated safety-sensitive functions, including operating a commercial motor vehicle. A physical CDL card does not override that restriction. Under Clearinghouse II, effective November 18, 2024, FMCSA notifies State Driver Licensing Agencies when a CDL or CLP holder is Prohibited. California DMV then removes the driver’s commercial driving privilege.

The driver should sign in to the Clearinghouse and review the violation record, record ID, reporting party, and return-to-duty progress. Certain factual or reporting errors may be addressed through a DataQs petition, while other inaccurate personal records may require a Privacy Act correction request. DataQs is not the ordinary route for disputing a drug or alcohol test result or a refusal determination. Filing a request does not suspend Prohibited status.

When the record is valid, the driver must designate a DOT-qualified Substance Abuse Professional. The SAP conducts an initial evaluation, prescribes any required education or treatment, performs a follow-up evaluation, and reports when the driver is eligible for return-to-duty testing. Eligibility alone does not change the driver to Not Prohibited.

A return-to-duty test must be ordered by a current or prospective DOT-regulated employer. An owner-operator uses a designated consortium/third-party administrator. After the applicable negative drug result or alcohol result below 0.02, the employer or C/TPA reports the result to the Clearinghouse. The status then changes to Not Prohibited.

California DMV states that commercial driving privileges are reinstated after the driver becomes Not Prohibited, but the driver should verify the DMV record before operating a CMV. For a renewal, replacement, or information update, DMV says to wait at least 24 hours after the Clearinghouse update. If the driver voluntarily obtained a noncommercial license, returning to a CDL may require knowledge and skills testing.

Return to duty does not end follow-up obligations. The plan requires at least six unannounced tests during the first 12 months of safety-sensitive duty and may continue for another 48 months. Not Prohibited also does not require an employer to rehire or return the driver to duty.
