FMCSA Clearinghouse: Returning to Duty After a Drug or Alcohol Violation

The Clearinghouse II changed the CDL reinstatement picture. Before November 2024, a driver with an unresolved violation couldn't be hired for safety-sensitive work, but they could still keep their CDL. That's no longer true. State DMVs now check the Clearinghouse when processing CDL renewals and transfers, and they're required to act on what they find. A driver who sits on a violation without starting the DOT return-to-duty process risks losing their license at the state level, not just their job.

The return-to-duty process itself hasn't changed. It's still a multi-step process that can take years to complete.

How Violations Work in the Clearinghouse

When a CDL driver violates DOT drug and alcohol regulations, the record shows up as unresolved. Employers querying the Clearinghouse can see it. Since November 2024, state DMVs can too.

These violations trigger a record:

• Verified positive drug test result
• Alcohol test result of 0.04 BAC or higher
• Refusal to test (includes substituted or adulterated specimens)
• Actual knowledge determination by the employer under 49 CFR §382.107

Clearinghouse Violation Statuses

There are five different statuses connected to Clearinghouse violations, indicating where in the process a driver is currently.

Employers often assume that once a driver passes the return-to-duty drug test, they can resume their safety-sensitive duties; however, employers must file a completion report before a driver's Clearinghouse record will reflect that they have successfully finished the return-to-duty process.

The Return-to-Duty Process

Step 1: Remove the driver. Pull them off safety-sensitive functions immediately. Document the time, date, and who made the call.

Step 2: Provide SAP referral. Give the driver a list of qualified Substance Abuse Professionals. This is your obligation under 49 CFR §40.287 — even if you're terminating the driver.

Step 3: Initial SAP evaluation. The SAP assesses the driver and prescribes what they must complete: education, outpatient treatment, inpatient treatment, or a combination.

Step 4: Driver completes treatment or education. The driver must follow exactly what the SAP prescribed.

Step 5: SAP follow-up evaluation. After treatment, the SAP verifies compliance and determines if the driver is ready to proceed. Some drivers will need additional treatment.

“The SAP evaluation is the gate that controls the entire process. There is no way around it, no employer override, and no accelerated timeline. The SAP decides when the driver is ready to proceed to the return-to-duty test.”

Step 6: Return-to-duty test. The SAP tests the driver under direct observation (49 CFR §40.67).

Step 7: Employer reports RTD completion to the Clearinghouse. This changes the status from unresolved to resolved. This is the most frequently missed step in the entire process, and skipping it can permanently derail the driver's career until someone corrects it.

Step 8: Driver returns to safety-sensitive functions. Only after the Clearinghouse shows a resolved status.

Step 9: Follow-up testing. The SAP prescribes a plan, involving a minimum of six unannounced tests in the first 12 months, up to 60 months total. These run separately from your regular random pool.

Hiring a Driver With Clearinghouse Violation History

You are required to obtain electronic consent and run a full query on every CDL hire before they start driving (49 CFR §382.701).

If that query results in an unresolved violation, the driver must complete the return-to-duty process before you can hire them for safety-sensitive duties.

If you hire a driver in the middle of their follow-up period, 49 CFR §40.307 assigns those remaining tests to you. Before the offer goes out, get the SAP's follow-up testing plan, records of tests already completed, and confirmation that the previous employer properly reported RTD completion. Getting all three before the hire prevents you from inheriting a compliance problem you didn't create.

State-Level CDL Impacts

Since November 18, 2024, state licensing agencies must check the Clearinghouse when processing CDL applications, renewals, and transfers. Drivers with unresolved violations will face a CDL downgrade. Applicants with open violations can't get a new CDL or CLP. Plus, CDL transfers from other states are screened automatically.

A potential issue for employers is that a driver who delays the return-to-duty process may end up with a downgraded CDL before the process is completed. Keep this in mind if you ever need to provide an SAP referral to a driver.

Common Employer Mistakes

Not reporting RTD completion to the Clearinghouse. The violation stays unresolved despite the driver passing every test. Fix this one yourself — don't wait for the driver to notice.

Letting a driver return before the Clearinghouse shows resolved. Passing the RTD test doesn't clear them. The status has to flip to resolved first. Putting someone behind the wheel with an unresolved status is a separate citable offense.

Ignoring inherited follow-up testing. Skipping mandated follow-up tests is a violation. It shows up in compliance reviews. Treat the schedule as seriously as your regular random pool.
