What to Do When Clearinghouse Shows Prohibited and California Downgrades a CDL
The CDL in your wallet may be unexpired and still in your possession when California DMV notifies you that commercial driving privileges have been removed. Your Drug and Alcohol Clearinghouse account may show “Prohibited.” Before returning to commercial driving, establish three separate facts: whether Clearinghouse has lifted the prohibition, whether the state record shows restored commercial privileges, and whether the employer has cleared your return or assigned work. Each depends on a different decision.
When must a driver with Prohibited status stop?
A driver marked Prohibited in Clearinghouse may not perform safety-sensitive functions for any DOT-regulated employer, including operating a commercial motor vehicle (CMV). The restriction applies regardless of whether freight is on board, how short the route is or whether the driver still has the physical CDL.
Beginning November 18, 2024, FMCSA notifies state driver licensing agencies of a driver’s Prohibited status. On notification, California DMV removes commercial driving privileges from the state record. Federal rules give the state agency 60 days to complete the CDL downgrade and record it on the driving record.
What should you check in the account?
Sign in to the official Clearinghouse account. Check the violation record, violation record ID and current return-to-duty (RTD) step. Save the page, notice date and applicable test documents. Verify the driver name, state, CDL or CLP number, violation type and reporting party.
For a wrong name, CDL number, reporting party or other correctable information, follow the DataQs review instructions. DataQs addresses record accuracy and whether the information was reported as required. It cannot redetermine a drug or alcohol test result or overturn a refusal determination. Use the procedure appropriate to that dispute. Other errors in personal records may require a Privacy Act request for correction. Prohibited status remains in force while FMCSA considers a request. Do not drive a CMV during that period.
If the record is correct, follow the RTD process
Designate a DOT-qualified Substance Abuse Professional (SAP) in Clearinghouse. The SAP conducts the initial evaluation and prescribes education and/or treatment appropriate to the case. Complete it and attend the follow-up SAP evaluation. Testing can begin only after the SAP determines that you are eligible for RTD testing. After the initial evaluation, disagreement with the recommendation does not entitle you to seek a second SAP evaluation.
Even after the SAP records eligibility for RTD testing, Clearinghouse still shows Prohibited. A current or prospective DOT-regulated employer must arrange the RTD test. The driver cannot complete this step by independently booking a collection. An owner-operator uses the designated consortium/third-party administrator (C/TPA).
A driver without a current or prospective employer can also proceed. Under the FMCSA procedure described at the review date, register in Clearinghouse in both driver and employer roles, select owner-operator and designate a C/TPA to arrange the test and report the result. A USDOT number is not required for this step, and FMCSA advises against obtaining one just for it.
The RTD drug test must be negative. For alcohol, the concentration must be below 0.02. Only after the employer or C/TPA reports the applicable negative RTD result does Clearinghouse change to “Not Prohibited.” Under the reporting rule described, employers generally must report by the end of the third business day after obtaining the information.
Check the state record after “Not Prohibited”
California DMV restores commercial driving privileges after Clearinghouse updates to Not Prohibited. Verify that the privilege has reappeared on the state record. Do not rely solely on the card. For an expiring, lost or stolen CDL, a replacement or a change of information, DMV calls for waiting at least 24 hours after Not Prohibited appears before starting the transaction.
A driver who retained the physical CDL during the prohibition may drive only noncommercial vehicles during that period. If the driver voluntarily obtained a noncommercial license in the meantime, California DMV’s guidance at the review date required the knowledge and skills/road tests again to regain a CDL. Check the relevant record and the California DMV commercial licensing page.
Follow-up testing continues after return to driving
On return to safety-sensitive work, complete the SAP’s follow-up testing plan. At least six unannounced tests are required in the first 12 months. The SAP may require more during the first year and extend testing for up to the following 48 months. A change of employer or a break from safety-sensitive work does not cancel the balance. Resume the outstanding tests when returning to covered work.
Not Prohibited does not decide whether an employer will rehire, return someone to duty or dispatch a load. That decision follows company policy and applicable law. Before driving, verify Not Prohibited status, restored commercial privileges on the California record and an explicit return-to-work or dispatch arrangement from the employer.
Keep records after completing the process
Keep SAP designation and evaluation dates, proof of completed education or treatment, RTD test arrangements and results, Clearinghouse status screenshots, DMV records and the employer’s written notices. A violation record generally remains for five years from the violation determination or until successful completion of RTD and the follow-up plan, whichever is later. A complete file helps when changing employers, continuing tests or disputing an error.
