What 382.401 means in plain language
FMCSR 382.401 requires motor carriers to maintain complete records of all controlled substances and alcohol testing they conduct on drivers. This isn't about whether a driver used drugs or alcohol—it's about whether your employer kept the paperwork.
When a carrier conducts pre-employment testing, random testing, post-accident testing, or reasonable-suspicion testing, they must document it all. Records must include test results, dates, times, the testing facility used, and the specific driver tested. If your carrier failed to keep these records organized and accessible, they've violated 382.401.
This is a carrier-level violation, not a driver violation. However, drivers working for a carrier with poor testing-record practices may face downstream consequences if an inspection uncovers missing or incomplete documentation.
What our enforcement data actually shows
Across our 13 million inspection records, we have found zero citations for 382.401 in the last 90 days, zero in the last 12 months, and zero all-time. This code has never been cited in our database.
With zero enforcement activity, the out-of-service rate is 0.0%—no drivers or vehicles have been placed out of service for this violation. This doesn't mean the violation never occurs in practice; it suggests that either carriers are complying reliably with testing-record maintenance, or that roadside inspectors prioritize other controlled-substance violations that show immediate driver impairment or possession.
Who gets cited most
Because there are no citations on record for 382.401, we cannot identify which states or carriers have been cited. Our data shows no enforcement activity in any state or against any carrier for this specific code.
How severe is this compared to similar codes
382.401 sits in the Controlled Substances/Alcohol category alongside more commonly cited violations. For perspective:
Use of drugs (code 392.4A-DOSP) has generated 3,947 citations with a 95.9% out-of-service rate. Use of drugs (code 392.4(a)) shows 3,919 citations with a 96.9% out-of-service rate. BAC 0.04+ (code 392.5(a)(2)) reflects 778 citations with a 99.2% out-of-service rate.
These peer codes are enforced far more frequently and carry much higher out-of-service rates because they involve actual driver conduct—drug use, alcohol use, or impairment—detected at roadside. By contrast, 382.401 is a record-keeping requirement that typically surfaces during carrier audits or detailed compliance reviews rather than during routine inspections.
How to avoid it
While 382.401 is a carrier responsibility, drivers can help their employer stay compliant:
- Confirm you've been tested before starting employment. Ask your dispatcher or safety department for a copy of your pre-employment drug and alcohol test result. If they can't produce it, alert them to the gap.
- Report to testing immediately when called for random testing. Request written confirmation (a receipt or reference number) that you completed the test. Keep it in your records.
- After any accident, cooperate fully with post-accident testing and request documentation. Ensure your carrier's safety team receives and files the results.
- If your carrier conducts reasonable-suspicion testing, ask for written notice of the suspicion and the test outcome. This creates a paper trail your carrier can use to prove compliance.
- During compliance conversations with dispatchers or safety personnel, never dismiss the request for test documentation. Missing or late paperwork is how 382.401 violations emerge.
Your carrier's compliance team should be the primary driver of these practices—they own the record-keeping obligation—but drivers who understand the requirement and cooperate promptly with testing requests reduce the risk that documentation gaps occur.
