FMCSR 382.603: Supervisor Training | Direct Answers

No. Our inspection records show a 0.0% out-of-service rate for FMCSR 382.603 citations. This violation addresses whether a designated supervisor completed required training on alcohol and substance abuse indicators—it is not an OOS-eligible offense. That said, the peer violations in the Controlled Substances/Alcohol category carry dramatically higher OOS rates: drug possession violations (392.4A-DOSP, 392.4(a), 392.4A-DOSU) range from 95.9% to 98.5% OOS rates, and alcohol-related violations (392.5(a) codes) consistently exceed 96.8% OOS rates. A 382.603 citation is administrative in nature.

A single 382.603 citation carries a CSA severity weight of 3 points. Within a 30-day rolling window, that single violation counts as 3 points toward your Safety Management Cycle score. The Controlled Substances/Alcohol basic category (BASIC 4) aggregates all violations in this group, so if you accumulate multiple alcohol or substance-related citations in the same 30-day period, their severity weights stack. For context, drug and alcohol possession violations in this category often carry the same or higher severity weights and generate far more citations across our 13 million inspection records.

First, request the inspection report and citation details from the DOT officer or your carrier immediately. Document the date, location, and inspector name. Second, confirm with your carrier or fleet safety manager that the designated supervisor has completed (or completes immediately) the required training on alcohol and substance abuse indicators. Third, request written proof of completion and file it with your safety records. If you believe the citation was issued in error—for example, if the supervisor had already completed the training—prepare documentation to contest it through the DataQs portal (FMCSA's online challenge system). Include training certificates or completion records as evidence.

No, 382.603 is significantly less severe than peer violations in the same category. While 382.603 has a 0.0% out-of-service rate, comparable Controlled Substances/Alcohol codes show vastly higher OOS rates: 392.4A-DOSP (drug use) at 95.9% OOS, 392.4(a) at 96.9%, and 392.5(a)(2) (BAC 0.04+) at 99.2%. Our inspection data shows 3,947 citations for 392.4A-DOSP alone versus 0 all-time citations for 382.603. A 382.603 citation is a compliance and training issue, not a driver conduct violation. Severity depends on enforcement context: repeated failures to ensure supervisor training could escalate compliance pressure, but a single citation is administrative.

Yes. FMCSA's DataQs portal allows drivers and carriers to challenge roadside inspection findings. For 382.603, contestability depends on the nature of the citation. If the inspector claimed the designated supervisor lacked required training but your carrier has documented proof of completion (training certificate, course transcript, attendance record), you can upload that evidence through DataQs to request record correction. DataQs challenges must be filed within a set window; check your citation for deadlines. If the training requirement itself is unclear or was in progress at the time of inspection, document the timeline. Successful challenges remove the violation from your CSA record.

No. Across our 13 million inspection records, FMCSR 382.603 shows zero all-time citations, zero citations in the last 12 months, and zero in the last 90 days. This violation is rarely enforced in roadside inspections. The Controlled Substances/Alcohol category (BASIC 4) is dominated by driver conduct violations—drug use (392.4A codes) and alcohol possession (392.5(a) codes)—which together account for tens of thousands of citations. A 382.603 citation is an outlier, typically issued during a comprehensive carrier audit or when an inspector encounters specific evidence that a designated supervisor never completed the training. If you receive one, it signals a compliance gap your carrier needs to close immediately.

A designated supervisor is an employee assigned responsibility for implementing a carrier's controlled substances and alcohol testing program. Their training requirement covers how to recognize observable indicators of alcohol and drug use in drivers—physical signs, behavioral clues, and performance issues. This training is foundational to a carrier's compliance with FMCSA substance abuse rules. A 382.603 violation means the DOT determined the designated supervisor had not received this required instruction. While the violation itself does not trigger an out-of-service order, it indicates a regulatory gap that could expose the carrier to broader compliance action. Immediate completion of the training closes the finding.

This violation is tied to the carrier's safety management system, not the individual driver. FMCSA tracks Controlled Substances/Alcohol (BASIC 4) violations for both drivers and carriers separately in the Safety Management Cycle. A 382.603 finding will appear on your carrier's compliance record and may affect the carrier's Safety Fitness Determination if repeated across multiple inspections. As a driver, you are not personally liable for the carrier's training compliance, but your employer's citation count influences the company's DOT safety rating. If your carrier receives citations for inadequate supervisor training, it signals systemic compliance weakness that could increase inspection frequency.
