FMCSA drug and alcohol compliance audits are documentation audits. Whether the review is a new entrant safety audit, a compliance review, or a follow-up to a prior finding, auditors evaluate the same thing: did your program take the right actions on time, and can your records prove it?
This checklist is written specifically for FMCSA-regulated motor carriers and their Designated Employer Representatives. Drug and alcohol audit requirements differ meaningfully across DOT operating agencies. FAA, FRA, FTA, and PHMSA each have their own regulatory frameworks and audit processes. This checklist does not attempt to cover those. It is focused on 49 CFR Part 382 and 49 CFR Part 40 as they apply to motor carriers employing CDL drivers in safety-sensitive functions.
The items below reflect what your program should have in place continuously, not a list of tasks to complete when an auditor calls. FMCSA auditors are experienced at identifying documentation that was assembled in response to an audit notice rather than maintained throughout the year. Treat this as a standing program management reference, not a pre-audit preparation tool.
Key Takeaways
- FMCSA drug and alcohol audits evaluate program execution and documentation under 49 CFR Part 382 and 49 CFR Part 40. Auditors verify that required testing occurred on time and that records support each action.
- The most common FMCSA audit findings are documentation gaps, not missed tests: pool roster drift, missing supervisor training records, incomplete post-accident timelines, and Clearinghouse compliance failures.
- FMCSA random testing rates are currently set at 50 percent for drug testing and 10 percent for alcohol testing. Every CDL driver performing safety-sensitive functions must be in the pool for the full period they hold that role.
- Clearinghouse compliance is an active FMCSA audit item. Pre-employment queries, annual limited queries, violation reporting, and return-to-duty entries all have specific requirements and timelines that the DER must manage.
- Employer responsibility does not transfer to a C/TPA. Working with a drug testing TPA means the TPA manages operational infrastructure. The motor carrier remains independently accountable for program execution and audit readiness.
- Several drug and alcohol testing records must be retained for five years under Part 382. Negative and canceled results are retained for two years. Auditors expect records to be produced on request, not retrieved from a third party after a delay.
The FMCSA Drug and Alcohol Program Audit Checklist
Review each category against your current program. Items you cannot produce or verify on demand represent gaps to address before an FMCSA auditor requests them.
Random Testing Records
- Random drug testing selections were conducted at or above the FMCSA-required 50 percent annual rate for the audit period
- Random alcohol testing selections were conducted at or above the FMCSA-required 10 percent annual rate for the audit period
- The selection method is scientifically valid and applied consistently throughout the year
- Every CDL driver performing safety-sensitive functions was included in the testing pool for the full period they held that role
- The pool roster accurately reflects your current driver list: no one missing who should be included, no one included who has left a safety-sensitive role
- Each selection has a corresponding completed test result
- Documentation of driver notification exists for each selection, including date and time (best practice, not explicitly required under Part 40, but strongly recommended)
- For any alternate selections used identify why an alternate was needed and who was the alternate for who.
- Any selections that were not completed are documented with a reason
Post-Accident Testing Records
Under 49 CFR Part 382.303, post-accident testing is required following any accident involving a fatality, or a combination of either a bodily injury requiring immediate medical treatment or a commercial motor vehicle that is towed along with a citation. The DER must initiate testing as soon as practicable.
- For each qualifying accident in the audit period, post-accident drug and alcohol testing was initiated as soon as practicable
- Alcohol testing was completed within two hours of the accident, or the reason it was not is documented; alcohol testing efforts ceased after eight hours with documentation
- Drug testing efforts were completed, or efforts ceased after 32 hours with documentation of why testing was not completed
- Records document the basis for the post-accident testing determination, including why the accident met the FMCSA qualifying criteria under Part 382.303
- Results and the full timeline for each qualifying accident are on file and can be produced immediately
Supervisor Training Records
Under 49 CFR Part 382.603, supervisors who make reasonable suspicion testing referrals must complete two hours of training before making any such referral: one hour on controlled substances and one hour on alcohol.
- Every supervisor with authority to make reasonable suspicion testing referrals has completed the required two hours of training
- Training was completed before each supervisor made any reasonable suspicion referral
- Training records document the date, the provider, and the subject matter covered
- Records can be produced on demand for every supervisor currently in a qualifying role
FMCSA Clearinghouse Records
The FMCSA Drug and Alcohol Clearinghouse is a federal database that motor carriers are required to query and report to. Clearinghouse compliance is reviewed in detail during FMCSA audits.
- A full Clearinghouse query was conducted for every new CDL driver before their first safety-sensitive assignment
- Annual limited queries have been conducted for all current CDL drivers within the required timeframe
- Refusals to test have been reported to the Clearinghouse by the DER within two business days
- Alcohol confirmation results of 0.04 BAC or greater have been reported to the Clearinghouse by the DER
- Actual-knowledge violations have been reported to the Clearinghouse by the DER
- MRO-reported positive drug test results are reflected in the Clearinghouse
- Return-to-duty activity is correctly recorded in the Clearinghouse, including SAP evaluation completion, RTD test results, and follow-up testing entries
Return-to-Duty and Follow-Up Testing Records
- For any CDL driver who had a program violation in the audit period, a complete return-to-duty file exists
- The file includes the SAP evaluation documentation and the SAP follow-up testing requirements
- The return-to-duty collection was directly observed and resulted in a verified negative result from the MRO before the driver returned to safety-sensitive duty
- Follow-up tests were unannounced and directly observed, meeting the minimum number and timeframe specified by the SAP (a minimum of six tests in the first 12 months)
- All Clearinghouse entries related to return-to-duty completion are current before the driver was returned to a safety-sensitive role
Annual MIS Report
FMCSA does not require all motor carriers to submit an annual Management Information System (MIS) report. Instead, FMCSA selects a sampling of carriers each year and specifically requests the MIS report from those selected carriers. If your carrier receives a request, you are required to respond with the requested testing data by the specified deadline. Maintaining organized records of your testing activity throughout the year ensures you can respond accurately and promptly if selected.
- If the carrier was selected by FMCSA for MIS reporting during the audit period, the requested report was submitted by the specified deadline
- Records of testing activity are organized and current so the carrier can respond to an MIS request accurately and without delay
- Copies of any submitted MIS reports are retained on file
Recordkeeping and Retention
- Chain-of-custody forms are on file for all tests conducted during the audit period
- MRO result reports are organized and accessible for all result types: positive, negative, dilute, canceled, and refusal
- Records are retained according to the Part 382 schedule: five years for some records, including positive results, and two complete calendar years for negative and canceled results
- Records can be produced immediately without routing the request through a third party
- The DER or designated record-keeper knows where all program records are located and can retrieve them on demand
What to Do When You Find a Gap
Working through this checklist and identifying items you can’t verify is useful information. The right response is to address the underlying process, not to reconstruct records retroactively. A documentation gap that existed during the program period is a gap regardless of when it is discovered. You can control how the program is managed going forward.
If you identify gaps in pool roster accuracy, Clearinghouse compliance, or supervisor training records, those are processes to correct and sustain. If the gaps suggest a program that is enrolled but not actively managed, that is the conversation to have with your C/TPA before an FMCSA auditor initiates it.
PROCOM’s drug testing TPA services include random pool management, selection administration, collection coordination, MRO services, Clearinghouse support, and audit-ready documentation maintained year-round. If your program has gaps which this checklist surfaces, that is the right starting point.

Frequently Asked Questions
FMCSA auditors review random testing records and pool roster accuracy, post-accident testing timelines and documentation, supervisor training certificates, MRO result reports, Clearinghouse query and reporting records, annual MIS reports, and return-to-duty documentation for any violations in the audit period. Auditors verify that required actions occurred on time and that records support each one.
Common triggers include new entrant safety audits required within the first 12 months of operation, compliance reviews following a qualifying accident or violation finding, follow-up audits after prior findings, and targeted reviews based on CSA Safety Measurement System data. Carriers with elevated scores in the Controlled Substances and Alcohol BASIC are more likely to receive a compliance review request.
Documenting driver notification for random testing is not explicitly required under 49 CFR Part 40, but it is strongly recommended. Written records of when each driver was notified and directed to report for testing help demonstrate that the test was unannounced, which is a core requirement of the random testing framework. Carriers who cannot show how or when notification occurred are in a weaker position if a selection is questioned during an audit.
Not automatically. A C/TPA manages the operational infrastructure of your testing program, including pool management, selection draws, and collection coordination. The motor carrier remains independently responsible for audit readiness. This means maintaining organized records, keeping the pool roster current, confirming Clearinghouse obligations are met, and producing documentation on request without routing it through a third party during the audit.
The Management Information System report is a summary of a motor carrier’s drug and alcohol testing activity. FMCSA does not require all carriers to submit this report annually. Instead, FMCSA selects a sampling of carriers each year and specifically requests the report from those selected. If your carrier receives a request, you must respond by the deadline provided. Maintaining organized testing records throughout the year is the best way to ensure you can fulfill an MIS request accurately if selected.
