How Missouri receives and acts on DACH notices

When a current Missouri CDL or CLP holder is updated to prohibited status, the Missouri Department of Revenue receives an automatic Drug and Alcohol Clearinghouse (DACH) notice through the Commercial Driver License Information System (CDLIS). Missouri immediately downgrades the driver's commercial status on the Missouri driver-license record and mails notice of the downgrade action. The commercial status remains downgraded until the driver completes the required Return-to-Duty process and is no longer prohibited in DACH.

Does Missouri automatically restore the CDL?

After the Return-to-Duty requirements are complete and DACH no longer shows the driver as prohibited, an automatic notification is sent to Missouri. The department then takes immediate action to restore an otherwise eligible driver's commercial status.

This applies when the driver's current credential remains a Missouri CDL or CLP and no separate licensing problem is keeping the driver withdrawn or downgraded. Missouri described its DACH action as immediate; it did not describe DACH restoration as occurring “in real time.”

Do I have to pay a Missouri Clearinghouse reinstatement fee?

For an otherwise eligible driver whose current credential remains a Missouri CDL or CLP, Missouri generally does not require a separate driver reinstatement application or Missouri DACH reinstatement fee after the automatic NOT PROHIBITED notification. This does not waive fees or requirements associated with a different suspension, revocation, denial, or disqualification.

What if you renewed as a noncommercial driver while prohibited?

If a prior CDL holder remains prohibited and applies for a noncommercial license at renewal, Missouri does not simply restore the CDL credential when DACH later clears. To obtain a CDL again, the driver must complete all applicable CDL knowledge testing and all applicable CDL skills testing.

This testing requirement is specific to the noncommercial-renewal scenario. Missouri did not state that every Clearinghouse downgrade requires CDL retesting.

What if your medical certificate expired?

Medical certification is a separate issue that can independently keep commercial status downgraded after DACH shows NOT PROHIBITED. A nonexcepted interstate driver with an expired medical examiner certificate must obtain a new certificate from a certified medical provider. The provider posts or transmits the certificate through the medical registry, and Missouri receives it electronically.

If the license number and name match Missouri's records and the driver's most current credential is still a CDL, Missouri states that this medical record update occurs in real time. No additional Missouri fee or separate compliance submission is required for that medical issue when the driver remains nonexcepted interstate and the new certificate is properly posted. The “real time” description applies to this medical-certificate update—not to DACH restoration timing.

What if you have another suspension?

A NOT PROHIBITED DACH status does not override another Missouri sanction. If the driver remains withdrawn because of a suspension, revocation, denial, or disqualification, the driver must separately satisfy the requirements for that sanction. Depending on the separate issue, examples may include an SR-22 filing, reinstatement fees, or an ignition interlock requirement. These are examples, not requirements for every driver.

What if the Clearinghouse prohibition was entered incorrectly?

Missouri DOR cannot override a DACH prohibition. An incorrect prohibition must be corrected within the federal DACH/Clearinghouse system. After DACH sends Missouri notice that the prohibition was removed or corrected, Missouri removes the related downgrade action and status, assuming no separate blocking issue remains.
