What the FMCSA rule actually says
Section 382.603 is four sentences long. Every employer must ensure that all persons designated to supervise drivers receive at least 60 minutes of training on alcohol misuse and at least an additional 60 minutes on controlled substances use. The training exists so the supervisor can decide whether reasonable suspicion exists to require a test under §382.307. It must cover the physical, behavioral, speech, and performance indicators of probable alcohol misuse and controlled substances use. And then the last sentence: recurrent training for supervisory personnel is not required. 49 CFR 382.603
Three things are missing from that text on purpose. There is no renewal interval. There is no expiration. And there is no approval process, provider list, or government certificate; the rule sets content and minutes and leaves the format to the employer. What the rule does fix is sequence: the observations behind a reasonable suspicion test must be made by a supervisor or company official who has already been trained. 49 CFR 382.307(c) Train before the first determination, and the federal minimum is met for as long as the person keeps the job.
Does the certificate expire?
Not under Part 382. Some providers print a “valid through” date or a recommended refresher date on the certificate. Others sell a renewal course on a calendar. Those are vendor conventions and company-policy choices, and they can be sensible ones, but they do not change the federal rule. A certificate with no date on it is not deficient, and a certificate with a date on it does not turn a voluntary refresher into a mandatory one.
What an investigator can actually ask for is the record: documentation of the training that qualified the supervisor to make reasonable suspicion determinations, and the employer’s certification that the training complied with the rule. 49 CFR 382.401(c)(5) For what that record needs to show, see the reasonable suspicion training certificate guide.
Agency by agency: who requires recurrent training
The six DOT agencies set the initial minutes differently and mostly say nothing about recurrence. Only FAA requires a recurrent program, and even FAA leaves the interval to the employer.
| Agency | Initial minimum | Recurrent requirement | Citation |
|---|---|---|---|
| FMCSA (motor carriers) | 60 min alcohol misuse + 60 min controlled substances | None. “Recurrent training for supervisory personnel is not required.” | 49 CFR 382.603 |
| FTA (public transit) | 60 min probable drug use + 60 min probable alcohol misuse | None stated. The rule sets initial minutes only. | 49 CFR 655.14(b)(2) |
| FAA (aviation) | At least 60 min initial for drug reasonable-cause determiners + 60 min alcohol | Yes, for drug determiners. A “reasonable recurrent training program … during subsequent years,” with no interval or minute count stated. The alcohol section states no recurrence. | 14 CFR 120.115(c)(4)14 CFR 120.223(b) |
| PHMSA (pipelines) | One 60-min drug period + at least 60 min alcohol | None stated in either section. | 49 CFR 199.113(c)49 CFR 199.241 |
| FRA (railroads) | A program of instruction on signs and symptoms; no minute minimum in the rule | None stated. The railroad’s FRA-inspectable program governs. | 49 CFR 219.11(g) |
| USCG (marine employers) | At least 60 min for supervisory personnel | None stated. | 46 CFR 16.401(b) |

When retraining is the right call anyway
“Not required” is not the same as “never useful.” These are the situations where a refresher earns its two hours, and the one situation where it is effectively mandatory.
Reasons to retrain a supervisor
- Your written policy promises a refresher
- 49 CFR 382.601
- If the company policy says supervisors are retrained every year or every two years, investigators will compare the training file to the policy. A promised refresher that never happened is a gap, even though the federal rule did not demand it.
- A state drug-free workplace program applies
- Several state premium-discount and drug-free workplace programs set their own supervisor-training schedules, and some of them are annual. Those schedules come from the state program, not Part 382. Check the program’s current rule before promising anyone that one federal course covers it.
- The supervisor changed employers
- 49 CFR 382.603
- Each employer must ensure its own designated supervisors are trained. Prior training counts, but only if the new employer can put the record on file. No record, no proof. Obtain the certificate and a description of the content, or retrain.
- The rules changed since the training
- Part 40 and Part 382 are amended from time to time. Training delivered years ago may describe collection procedures, forms, or reporting steps that no longer match the current text. The indicators of impairment do not change; the paperwork around them does.
- The documentation has been weak
- 49 CFR 382.307(f)
- If a supervisor’s observation record reads “seemed off” instead of a timed list of what was seen, heard, and smelled, the training has faded whether or not the certificate is on file. A two-hour refresher costs less than one test thrown out for a thin record.
- A long gap with no determinations
- A supervisor who has not made a reasonable suspicion call in five years will hesitate when it matters. Hesitation is how the two-hour alcohol window closes. A refresher is a cheap way to keep the decision fast.
- A customer or contract requires it
- Shipper and broker contracts sometimes require annual supervisor training as a condition of hauling for them. That is a contract term, enforced by the customer, and it sits on top of the federal minimum.
Do you need to retrain this supervisor?
Can you produce a record showing this person completed at least 60 minutes on alcohol misuse and 60 minutes on controlled substances, with the date, the provider, and the topics covered?
Does this supervisor make drug reasonable-cause determinations for an FAA-regulated program?
Yes: A reasonable recurrent training program is required in subsequent years under 14 CFR 120.115(c)(4). Set an interval in writing and keep to it.
No: Continue to question 3.
Does your written policy, a state drug-free workplace program, or a customer contract set a refresher interval?
Yes: Follow that interval. It is enforceable by whoever set it, and your own policy will be compared to your training file.
No: Continue to question 4.
Has the supervisor made a determination in recent memory, and did the written record hold up?
Yes: No retraining is required. Keep the record for as long as the supervisor holds the role and for two years after.
No: Nothing forces it, but a refresher now is cheaper than a hesitant call or a thin record later.
How long to keep the training record
Supervisor training records fall under the “indefinite period” line of the retention schedule: keep them while the individual performs the functions that require the training and for two years after the individual stops. 49 CFR 382.401(b)(4) That is a different clock from the one on the reasonable suspicion decisions themselves. Documents generated in deciding to order a test are collection-process records and are kept for two years; documentation of a refusal is kept for five. 49 CFR 382.401(b)(1)–(2)
- Store the records in a secure location with controlled access. 49 CFR 382.401(a)
- Be able to produce them at the principal place of business within two business days of an FMCSA request. 49 CFR 382.401(d)
- When a supervisor leaves, do not purge the file. Date the departure and start the two-year count from it.

Frequently asked questions
Does FMCSA reasonable suspicion training expire?
No. 49 CFR 382.603 sets a one-time minimum of 60 minutes on alcohol misuse and 60 minutes on controlled substances and states that recurrent training for supervisory personnel is not required. The federal rule attaches no expiration date to the training. What does have a clock is the record: the employer must keep the supervisor’s training documentation for as long as the supervisor performs the function and for two years after.
Is reasonable suspicion training required annually?
Not under FMCSA, FTA, PHMSA, FRA, or USCG rules, none of which states a renewal interval. FAA is the exception: an employer whose supervisors make drug reasonable-cause determinations must run a reasonable recurrent training program during subsequent years, although 14 CFR 120.115 sets no fixed interval or minute count for it. A company policy, a state drug-free workplace program, or a customer contract can require annual refreshers on its own authority.
Do I have to retake reasonable suspicion training when I change companies?
The rule puts the duty on each employer to ensure that every person it designates to supervise drivers has received the training. Training from a previous employer or provider satisfies that duty if the new employer can put the documentation on file. If the certificate and a description of what it covered cannot be obtained, the new employer has no record to show, and retraining is the practical fix.
Why does my certificate show an expiration or renewal date?
Some providers print a validity period or recommend a refresher date. That is a vendor or company-policy convention, not a federal requirement. A certificate without an expiration date is not deficient, and a certificate with one does not make retraining mandatory under Part 382.
How long must the employer keep the supervisor training record?
Under 49 CFR 382.401(b)(4), records related to the education and training of supervisors are kept for as long as the individual performs the functions that require the training and for two years after the individual stops performing them. The records must sit in a secure location with controlled access and be available at the principal place of business within two business days of an FMCSA request.
Does the awareness course for non-supervisors need to be renewed?
No federal rule requires it, because no federal rule requires the awareness course in the first place. Awareness training for employees who only escalate concerns to a trained supervisor is a policy choice. It is not a substitute for the §382.603 supervisor training, and it does not carry a renewal interval of its own.
Do drivers need recurring drug and alcohol training?
Part 382 requires employers to give drivers educational materials and the company policy before testing begins and again when a driver is hired or transferred into a driving position, with a signed receipt kept on file. That is a distribution requirement under §382.601, not timed training with a renewal interval.
