Since November 18, 2024, a failed or refused DOT drug or alcohol test can cost CDL drivers more than their job. Under FMCSA’s Clearinghouse II rule, your state must downgrade your commercial license while your Clearinghouse status is prohibited.
What changed with Clearinghouse II
Before, a prohibited status mainly stopped employers from putting you behind the wheel. Now, state licensing agencies receive your Clearinghouse status directly. If you’re prohibited, the state must remove your commercial driving privilege from your CDL or CLP.
How fast does a downgrade happen?
States must complete the downgrade within 60 days of being notified by FMCSA. This is not a grace period. You can’t legally drive a commercial vehicle while your status is prohibited, whether or not the downgrade has happened yet.
What “prohibited” means
Your Clearinghouse status is prohibited from the moment a drug or alcohol violation is reported. It stays prohibited until every return-to-duty step is complete and the negative return-to-duty test result is reported.
How to get your CDL back
- Register in the FMCSA Clearinghouse and designate your SAP
- Complete your initial SAP evaluation
- Complete the education or treatment recommended
- Complete your follow-up evaluation (your SAP reports the compliance date)
- Take a return-to-duty test directed by an employer or your C/TPA
- Once the negative result is reported, your status changes to not prohibited
When your status changes to not prohibited, your state must reinstate your CDL or CLP. Check with your state licensing agency for any extra steps or fees.
Can starting early prevent a downgrade?
Starting the SAP process alone doesn’t stop a downgrade. Only finishing every step changes your status. But starting right away is the only way to give yourself a chance of finishing sooner, and it shortens the time your CDL stays downgraded.
Frequently asked questions
Does this apply to transit, rail or aviation workers?
Clearinghouse II applies to CDL and CLP holders under FMCSA rules. Other DOT agencies don’t use the Clearinghouse.
Do owner-operators need a C/TPA?
Yes. Owner-operators need a consortium or third-party administrator to direct and report the return-to-duty test.
Will my violation stay in the Clearinghouse?
Violation records remain for five years or until the return-to-duty process and follow-up testing are complete, whichever is later.
