The DOT Return-to-Duty Process

You failed a DOT drug or alcohol test, or you refused one, and you are trying to figure out whether the job comes back. Safety-sensitive work stops until a substance abuse professional finishes an evaluation and the education or treatment they require. Tonight, ask the employer for the list of those professionals. Do not shop for a second opinion. Do not stop a prescribed medicine or heavy drinking so the next test will look cleaner.

If you are in immediate danger, call 911. For a mental health crisis, call or text 988.

The work stops until one evaluation is finished

After a DOT drug or alcohol violation, you cannot perform safety-sensitive duties for any employer until you complete the substance abuse professional's evaluation, referral, and education or treatment. The violations named there are a verified positive drug test, an alcohol test at 0.04 or greater, a refusal to test (including adulterating or substituting a specimen), and any other violation of a DOT agency ban on alcohol or drug use. What a positive result means outside this rule, including a lawful prescription, is in a failed workplace drug test.

If your job is not a DOT safety-sensitive function, do not borrow this process. An office policy, a hospital policy, or a licensing board can be different. Ask which rule you are under.

The employer must give you a list of substance abuse professionals who are readily available, with names, addresses, and phone numbers, and cannot charge you for the list. The employer does not have to pay for the evaluation or the care. A name on an employee assistance poster may or may not be qualified for this role. An employee assistance program is a workplace benefit, described in EAP and substance use. Ask whether the person on the list has completed the DOT training and exam, not only a clinical license.

The evaluation is one clinical assessment, a referral to education or treatment, a later check on whether you complied, a follow-up testing plan for the employer, and any recommendation for continuing care. It can be in person or by real-time video. The professional is not an advocate for you or for the employer. The stated job is public safety. Every person who violated the rule gets a recommendation for education or treatment, and the plan has to be individual. Education can include verified attendance at a group such as Alcoholics Anonymous. Treatment can include a hospital, a day program, outpatient counseling, or aftercare.

You do not get a kinder second evaluation. The employer may not rely on one you obtained anyway. Nobody else may rewrite the recommendation. The same professional may revise it when new information arrives. The professional must assume a verified positive test established the violation. Claims about hemp oil, medical marijuana, poppy seeds, or job stress are not reasons the rule lets them soften the plan. They also must not refer you to their own practice, with a few written exceptions: a public agency, the employer or its contracted provider, the only appropriate care your insurance covers, or the only appropriate care reasonably available.

Do not stop heavy drinking on your own to sit another test. A sudden stop after chronic heavy drinking can be life-threatening. Stopping a benzodiazepine abruptly, or cutting it too fast, can cause seizures.

Compliance is not a right to the job

If the employer wants to permit safety-sensitive work again, the return-to-duty test happens only after the professional finds that you complied. The result must be a negative drug test, an alcohol test under 0.02, or both. The employer must not put you back before that test. The employer also does not have to put you back because you passed. Compliance can be found even when the rest of the plan is still ahead. The regulation's example is finishing a 30-day inpatient program while outpatient counseling is still to come. If you have not complied, you do not return to safety-sensitive duty.

Follow-up testing is written only after compliance. The rule requires at least six unannounced tests in the first 12 months back on safety-sensitive duty. The professional chooses how many, how often, and whether they are for drugs, alcohol, or both. They may add tests during the next 48 months. They do not set the calendar dates. The employer does. You do not get a copy of the schedule, and no one is allowed to tell you the frequency. The schedule follows you to a later employer. Altering or substituting a specimen is itself a refusal.

The professional may recommend ongoing education or support after you are back. The employer may put that in a return-to-duty agreement. That monitoring does not replace the follow-up tests. Leave and whether a license survives are separate questions, in workplace leave. How to talk with an employer you still have is in talking with your boss.

FindTreatment.gov lists treatment programs. Use the employer's list for who is qualified under this rule. Call or text (800) 653-9376 if you need help finding care after you already have that list.
