What to Do When a New Hire Has a Clearinghouse Violation

You've found a qualified CDL driver. The application looks good, the MVR is clean, and you're ready to move forward. Then the FMCSA Clearinghouse full query comes back with a violation. A positive drug test. An alcohol concentration of 0.04 or greater. A refusal to test. Now what?

A Clearinghouse violation doesn't automatically disqualify a driver from employment, but it dramatically changes your onboarding process. Whether you can hire the driver — and what hoops you'll need to jump through — depends entirely on where the driver stands in the return-to-duty process.

Types of Clearinghouse Violations

The FMCSA Drug and Alcohol Clearinghouse records violations of 49 CFR Part 382 — the DOT drug and alcohol testing regulations. Understanding the type of violation determines your path forward.

Positive Drug Test

A verified positive result on a DOT drug test for one or more of the five federally mandated drug classes: marijuana, cocaine, amphetamines, opioids, or phencyclidine (PCP). This is the most common violation type. The violation remains in the Clearinghouse until the driver completes the return-to-duty process and all follow-up testing requirements are satisfied.

Alcohol Violation

A confirmed alcohol concentration of 0.04 or greater on a DOT alcohol test. This includes breath alcohol tests and blood alcohol tests conducted under DOT protocols. Even a result of 0.04 exactly — which might seem borderline — is a violation. An alcohol concentration between 0.02 and 0.039 is not a violation under Part 382 but does require the driver to be removed from safety-sensitive duties for 24 hours.

Refusal to Test

A refusal to submit to a required drug or alcohol test. Refusals are treated the same as a positive result under DOT regulations. Refusals include:

• Failing to appear at the collection site within the required time
• Failing to provide an adequate specimen without a valid medical explanation
• Tampering with, substituting, or adulterating a specimen
• Leaving the collection site before the process is complete
• Refusing to undergo a directly observed collection when required

Actual Knowledge Violations

An employer reports an "actual knowledge" violation when they have direct evidence that a driver used drugs or alcohol in violation of the regulations — even without a test. This might include direct observation of use, admission by the driver, or physical evidence. Actual knowledge violations carry the same consequences as a positive test.

Can You Still Hire a Driver With a Violation?

Yes — but only if the driver has completed the return-to-duty (RTD) process. Here's the critical distinction:

Violation With No RTD Completion: Cannot Hire

If the Clearinghouse shows a violation and the driver has not completed the return-to-duty process, you cannot put this driver behind the wheel. Period. Under SS382.501(a), no employer may allow a driver to perform safety-sensitive functions — including driving a CMV — if a Clearinghouse query reveals an unresolved violation.

This applies even if the driver claims to have completed the process. The Clearinghouse is the official record. If the SAP (Substance Abuse Professional) hasn't reported the completion, it didn't happen as far as the regulation is concerned.

Violation With Completed RTD: Can Hire (With Conditions)

If the Clearinghouse shows a violation with a completed return-to-duty process, the driver is eligible for safety-sensitive duties — but you inherit follow-up testing obligations. The violation will still appear on the query results, but it will show a status indicating RTD completion.

The Return-to-Duty Process: What the Driver Must Complete

Before a driver with a violation can return to safety-sensitive functions, they must complete every step of the RTD process under 49 CFR Part 40, Subpart O:

• Evaluation by a SAP — a DOT-qualified Substance Abuse Professional conducts a face-to-face clinical assessment and determines what treatment or education the driver needs
• Complete prescribed treatment — the driver completes whatever program the SAP recommends (inpatient treatment, outpatient counseling, education programs, or a combination)
• Follow-up evaluation by the same SAP — the SAP who conducted the initial evaluation must confirm the driver has successfully complied with all treatment recommendations
• Return-to-duty test — the driver passes a directly observed drug test (and/or alcohol test, depending on the violation type) with a verified negative result
• SAP reports to Clearinghouse — the SAP updates the Clearinghouse with completion information, including the follow-up testing plan

This process typically takes 2-6 months but can take longer depending on the SAP's treatment recommendations and the driver's compliance.

Follow-Up Testing: What You Inherit as the New Employer

This is the obligation that catches many carriers off guard. When you hire a driver who has completed the RTD process, you become responsible for their follow-up testing plan. This is not optional, and it's in addition to your regular random testing program.

Minimum Follow-Up Testing Requirements

• At least 6 directly observed tests in the first 12 months — this is the DOT minimum; the SAP may prescribe more
• Testing can extend up to 60 months — the SAP determines the total duration based on the driver's clinical situation; 12 months is the minimum, but the SAP may require follow-up testing for up to 5 years
• Tests must be unannounced — the driver cannot know in advance when they will be tested
• Tests are directly observed — a same-gender observer must watch the specimen collection; this is more stringent than standard random testing
• Any positive follow-up test restarts the entire process — the driver is immediately removed from safety-sensitive duties and must go through the full SAP evaluation and RTD process again

Getting the Follow-Up Testing Plan

The SAP's follow-up testing plan should be available in the Clearinghouse records. When hiring a driver with a completed RTD, request documentation of:

• The SAP's name and contact information
• The specific follow-up testing schedule (number of tests, duration, type)
• How many follow-up tests have already been completed by the previous employer
• Results of all completed follow-up tests

If the previous employer completed some but not all follow-up tests, you pick up where they left off. You do not restart the count.

Documentation You Need Before Hiring

Hiring a driver with a Clearinghouse violation requires significantly more documentation than a clean hire. Before the driver operates a CMV, assemble all of the following:

• Clearinghouse full query results — showing the violation and RTD completion status
• SAP initial evaluation report — confirming the assessment was completed and treatment was prescribed
• SAP follow-up evaluation report — confirming the driver successfully completed all prescribed treatment
• Return-to-duty test result — verified negative, directly observed
• Follow-up testing plan — the SAP's written plan specifying number, frequency, and duration of follow-up tests
• Records of any completed follow-up tests — from the previous employer, with results
• Your own follow-up testing schedule — documenting when you will conduct the remaining required tests

Insurance Implications

This is where the business decision gets complicated. Even when a driver is legally eligible to drive after completing RTD, your insurance carrier may have a different opinion.

What to Expect From Your Insurer

• Some insurers will not cover drivers with Clearinghouse violations — review your policy's driver eligibility criteria before making an offer
• Premium increases are common — even insurers that accept these drivers may charge higher rates, sometimes significantly higher
• Notification requirements — many policies require you to notify the insurer when adding a driver with a violation history; failure to disclose can void coverage
• Liability exposure — if the driver is involved in an accident and your insurer discovers an undisclosed Clearinghouse violation, they may deny the claim or refuse to defend the lawsuit

Contact your insurance agent before extending an offer to a driver with a Clearinghouse violation. Get written confirmation of coverage and any conditions or premium adjustments. This conversation should happen before the driver completes a single mile for your company.

The 10-Year Drug and Alcohol History Check

In addition to the Clearinghouse query, you're required to obtain drug and alcohol testing history from all DOT-regulated employers for the past 3 years (the safety performance history request under SS391.23). However, the Clearinghouse itself retains violations for 5 years from the date of the violation determination.

For pre-2020 violations (before the Clearinghouse existed), the previous employer verification process under SS40.25 covers a 2-year look-back for drug and alcohol testing records. Carriers who do thorough background checks may also request records going back further, though this is not required by regulation.

Making the Hiring Decision

A Clearinghouse violation creates a decision matrix with several factors:

Factors Favoring Hiring

• The driver has fully completed the RTD process with no issues
• Significant time has passed since the violation (2+ years)
• The violation was a first offense
• Follow-up testing is nearly complete with all negative results
• Your insurance carrier has confirmed coverage
• The driver's overall record is otherwise clean

Factors Against Hiring

• RTD was completed recently and most follow-up tests remain
• Multiple violations in the Clearinghouse history
• The violation involved a refusal to test (which suggests deliberate evasion)
• Your insurance carrier will not cover the driver or requires prohibitive premiums
• The driver cannot provide documentation of completed follow-up tests from prior employers

What Happens If You Hire Without Checking

Failing to conduct the pre-employment Clearinghouse full query before allowing a driver to operate a CMV is a violation of SS382.701. Penalties include fines up to $16,000 per violation. But the real risk is larger: if you unknowingly put a driver with an unresolved violation behind the wheel and they're involved in an accident, the liability exposure is catastrophic. Plaintiff attorneys routinely check the Clearinghouse during litigation, and a missed query is evidence of negligent hiring.

Ongoing Monitoring

After hiring a driver with a completed RTD, your obligations don't end:

• Conduct all follow-up tests on schedule — missing even one is a violation
• Document every test with date, type, observer, and result
• Run the annual limited Clearinghouse query to check for new violations
• Keep the SAP's follow-up testing plan in the driver's file
• If the driver leaves your company before follow-up testing is complete, report the remaining testing obligations to the next employer upon request

Hiring a driver with a Clearinghouse violation is legal, manageable, and sometimes the right business decision — especially for experienced drivers who made a single mistake, completed treatment, and have been clean since. But it requires more documentation, more testing, and more oversight than a standard hire. Go in with your eyes open, your insurance confirmed, and your follow-up testing calendar set before the driver turns a wheel.
