49 CFR Part 40 drug and alcohol testing supplies for DOT-regulated employers.

Yes. Under §382.103, any employer of a CDL driver in interstate commerce, including a one-truck owner-operator, must comply with Part 382 and Part 40. Owner-operators typically join a C/TPA's random consortium pool to meet the random testing requirement, since an operator cannot administer a random pool of one. ASC supplies the consortium and the owner-operator's collection site with the same federal CCFs and SAMHSA-5 cups.

FMCSA sets the minimum annual random rate (currently 50% for drugs, 10% for alcohol). For a 200-driver pool that's 100 drug tests and 20 alcohol tests per year, distributed unannounced across the calendar, typically with monthly draws. Build in a buffer for post-accident, reasonable suspicion, return-to-duty, and follow-up tests, since FMCSA reviews and can adjust these minimum rates. ASC's fleet rep can help model your pool size against current agency rates.

The HHS-certified lab transmits the confirmed result directly to the MRO. The MRO then contacts the donor for a verification interview to assess legitimate medical explanations before reporting the verified result to the DER. As the employer, you provide the MRO with the driver's contact info and authorize the program, but you do not see the lab result until the MRO has verified it. ASC's CCFs route results to the MRO copy automatically.

ASC supplies the EBT and ASD devices on the NHTSA Conforming Products List, though we don't certify BAT operators ourselves. Your BAT (Breath Alcohol Technician) must complete DOT-model BAT training and demonstrate proficiency on your specific EBT model. Re-qualification is required every five years per §40.213, plus error-correction training within 30 days of any procedural error.

Alcohol testing must be performed within 8 hours of the qualifying accident; drug testing must be performed within 32 hours. If the windows are missed, the employer must document the reason and stop attempting testing. Post-accident testing is only required when the accident meets the qualifying criteria (fatality, citation + bodily injury, or citation + tow-away). ASC's post-accident kits are pre-staged at each terminal so you don't burn the 8-hour clock chasing a UPS delivery.

Under §40.191, refusal is treated the same as a verified positive. Behaviors that count as refusal include failing to appear, leaving the collection site, failing to provide adequate specimen without a valid medical explanation, refusing to sign the CCF, or refusing the directly-observed collection when required. The driver must be immediately removed from safety-sensitive duty, reported to the FMCSA Clearinghouse, and cannot return to safety-sensitive functions until completing the SAP process under Subpart O.

The FMCSA Drug and Alcohol Clearinghouse requires employers and C/TPAs to report DOT drug and alcohol program violations, refusals, and return-to-duty actions for CDL drivers. Employers must run a query on every new CDL hire (a full query, with driver consent) and annual queries on current drivers. ASC's reporting templates and CCF formats align with Clearinghouse reporting fields so your C/TPA can transmit without re-keying.

DOT testing rules apply across several modes of transportation, each under its own agency: commercial motor carriers regulated by the FMCSA (CDL drivers), aviation employees regulated by the FAA (pilots, flight crews, and instructors), maritime crew members operating a commercial vessel regulated by the USCG, transit employees such as vehicle operators, controllers, and armed security regulated by the FTA, and railroad employees regulated by the FRA.

The employee is required to bring a photo ID, such as a driver's license, and the Custody and Control Form (CCF) to the collection site. The DOT testing process also includes safeguards to check for dilution or substitution in the urine sample: the specimen must fall within a temperature range of 90 to 100 degrees Fahrenheit shortly after collection, or the collector takes steps to verify it came directly from the donor.

The MRO's verification statement determines whether a second collection is required. For a random test, no second collection is typically needed. For a pre-employment, return-to-duty, or follow-up test, the employer generally needs to arrange a second collection.
