DOT drug and alcohol testing requirements for CDL drivers

If your drivers need a CDL, you need a DOT drug and alcohol testing program under 49 CFR Part 382 (§382.103(a)). That means six kinds of test: pre-employment, random, post-accident, reasonable suspicion, return-to-duty and follow-up. Random testing has to reach at least 50 percent of your average driver positions for drugs and 10 percent for alcohol each year, unless FMCSA publishes different rates (§382.305(b)).

Who the rules cover

Part 382 applies to employers and drivers who operate a commercial motor vehicle in commerce and are subject to the CDL requirements of Part 383. The usual exceptions in §390.3T(f) don't carry over here, so some operations exempt from other safety rules still have to test (§382.103(c)).

Owner-operators get a rule of their own. If you employ only yourself as a driver, you still have to be in a random testing pool of two or more covered employees (§382.103(b)). In practice that means joining a consortium run by a consortium or third-party administrator, which pools you with other small carriers for random selection.

The six tests and when each one happens

Pre-employment

A driver can't perform safety-sensitive functions for you until you've received a verified negative drug test result from the medical review officer or your administrator (§382.301(a)). There's a narrow exception for a driver who was in a compliant program within the previous 30 days and was recently tested or in a random pool, with conditions set out in §382.301(b). The pre-employment Clearinghouse query is a separate step, covered in the Clearinghouse query guide.

Random

Selection has to use a scientifically valid method, such as a computer random number generator matched to employee or payroll numbers, and every driver must have an equal chance each time selections are made (§382.305(i)). Tests are unannounced and spread reasonably through the year (§382.305(k)). A driver who's told they've been selected goes to the test site immediately.

The 50 and 10 percent figures are the baseline in the regulation. FMCSA can raise or lower them based on industry violation rates and publishes any change in the Federal Register, taking effect on 1 January of the following year (§382.305(c)). Check the current year's notice before you plan your selections.

Post-accident

After a crash on a public road, test each surviving driver who was performing safety-sensitive functions when the crash involved a death. When nobody died, test the driver if they receive a citation for a moving violation arising from the crash and someone was immediately treated away from the scene or a vehicle had to be towed because of disabling damage. The citation window depends on the test: within 8 hours of the crash for alcohol, and within 32 hours for drugs (§382.303(a), (b)).

Timing matters. If the alcohol test isn't done within 2 hours, write down why. At 8 hours, stop trying and keep that record. For drugs, stop at 32 hours and record the reason (§382.303(d)).

Reasonable suspicion

A supervisor orders a test based on specific, contemporaneous observations of the driver's appearance, behavior, speech or body odor (§382.307). A hunch or a rumor isn't enough; write down what was seen, when and by whom.

Return-to-duty and follow-up

After a violation, a driver goes through the return-to-duty process in 49 CFR Part 40, subpart O, which runs through a substance abuse professional (§382.309). Once they're back, the follow-up testing schedule set in that process applies (§382.311).

What a DOT drug test checks for

The urine panel covers marijuana metabolites, cocaine, opioids (codeine, morphine, hydrocodone, hydromorphone, oxycodone, oxymorphone and heroin's 6-acetylmorphine), phencyclidine, and amphetamines including methamphetamine and MDMA. The laboratory cutoffs are set in 49 CFR 40.85. Alcohol is tested separately.

How long to keep testing records

Keep the records in a secure place with controlled access (§382.401(a)). The retention periods depend on the record:

• Five years: alcohol results of 0.02 or greater, verified positive drug results, refusals, evaluations and referrals, calibration records, program administration records and each annual summary.
• Two years: records of the collection process.
• One year: negative and cancelled drug results and alcohol results below 0.02.
• Training records: for as long as the person does the job that needs the training, plus two years.

Those periods come from §382.401(b). The record retention guide puts them alongside the rest of a carrier's files.

Example: a two-truck carrier

A carrier with two CDL drivers hires a third. The new driver takes a pre-employment test, and the carrier waits for the verified negative and the Clearinghouse query result before the first load. All three drivers sit in the consortium's random pool with other small carriers. Over the year, some are selected more than once and some not at all, which is how random selection is supposed to work. The carrier keeps each negative result for a year and each program record for five.

Keeping each driver's testing records next to their qualification file makes it easier to answer a request without searching several places. Ledger Road keeps driver records together with their renewal dates.
