What 382.305 means in plain language
FMCSR 382.305 addresses a carrier-level compliance obligation, not a driver behavior violation. This regulation requires motor carriers to conduct random controlled substances and alcohol testing of their drivers at rates specified by the Department of Transportation. When a carrier fails to implement or maintain a random testing program at the required frequency, they are in violation of 382.305.
The regulation applies to carriers with Commercial Motor Vehicle (CMV) operations. The carrier must establish a system to randomly select drivers and subject them to drug and alcohol tests according to federal minimums. This is a preventive program requirement—the carrier is responsible for the infrastructure and execution, even though the tests themselves involve individual drivers.
What our enforcement data actually shows
Across our 13 million+ inspection records, 382.305 has a distinctly different enforcement profile than most FMCSR violations. Our database shows zero citations for this code in the last 90 days, zero in the last 12 months, and zero all-time. This means roadside inspectors are not currently citing carriers for failure to conduct random testing under this specific code.
Because there are no citations in our data, there is no out-of-service rate to calculate. The code is not designated as OOS-eligible, meaning even if a violation were found, it would not automatically result in a vehicle being placed out of service on the spot.
The absence of enforcement data for 382.305 does not mean random testing is not required—it reflects the practical reality that this violation is typically caught during compliance reviews, audits, or carrier-level investigations rather than at the roadside.
Who gets cited most
With zero citations in our enforcement database, we cannot identify state-level or carrier-level patterns. No state appears in the top_states list for this code, and no specific carriers show up in citation records. This makes 382.305 categorically different from other Controlled Substances/Alcohol codes, which generate thousands of citations annually.
How severe is this compared to similar codes
382.305 belongs to the Controlled Substances/Alcohol category, but it operates on a different enforcement level than the violations that dominate our data. Compare it to peer codes:
392.4A-DOSP (Use of drugs) has generated 3,947 citations with a 95.9% out-of-service rate. 392.5A2-IP (Driver under influence of alcohol) shows 691 citations with a 99.0% out-of-service rate. 392.5(a)(2) (BAC 0.04+) has 778 citations with the highest OOS rate at 99.2%.
These peer codes target driver conduct during or before a duty cycle. By contrast, 382.305 targets the carrier's testing program itself. The zero-enforcement profile suggests that DOT and state enforcement agencies focus roadside resources on catching drivers with actual substances or impairment rather than investigating whether a carrier's testing frequency meets the minimum annual percentage rate.
How to avoid it
If you are a driver employed by a carrier, you cannot directly comply with 382.305—your carrier must. However, you should verify that your employer has a documented random drug and alcohol testing program before you start driving for them:
- Ask your HR or safety department whether the carrier is enrolled in a DOT-approved random testing consortium or operates its own testing program. Request documentation showing the annual testing rate.
- Verify the testing requirement is active at your hiring orientation. Your carrier should inform you of the testing schedule and your obligations if randomly selected.
- Understand that random selection is exactly that—random. If selected, refusal to test or a positive result will have immediate driver-level consequences under 392.4 and 392.5 codes, which carry near-certain out-of-service placements.
- Stay compliant with any required medical evaluations (DOT physicals, medical examiner certifications) before you are placed in a random testing pool. Carriers cannot test drivers who do not hold valid medical certificates.
- Know your carrier's testing vendor and process. If selected, know where to go and within what time window. Delays in reporting for a test can be treated as a refusal.
As a fleet safety manager building a prevention program, ensure your random testing plan is current, documented, and accessible to auditors. Assign clear ownership of testing execution and keep records of every test conducted, declined, or refused. While 382.305 is not a frequent roadside enforcement point, an audit or CSA investigation of your carrier will examine your testing rate compliance directly.
