FMCSA drug and alcohol testing records: what to retain
An FMCSA-regulated motor carrier cannot put every drug and alcohol programme document under one “keep for five years” label. 49 CFR § 382.401 sets different minimum periods for different records and requires a secure location with controlled access. The employer needs to classify the record, know who may access it and be able to produce it when an authorised FMCSA representative requests it.
This guide covers motor-carrier employers subject to FMCSA Part 382. Other DOT modes may have their own agency rules; the DOT-wide testing procedures in 49 CFR Part 40 do not make every mode's record schedule identical. Confirm programme coverage before applying this table to a driver or worker.
Map the record to the rule
The current section 382.401 sets these minimum categories for motor-carrier employer records:
| Minimum retention | Examples in the current rule |
|---|---|
| Five years | Alcohol results of 0.02 or greater; verified positive controlled-substances results; refusals; driver evaluation/referral records; calibration documentation; programme administration records including driver violations; annual summaries required by § 382.403. |
| Two years | Records related to the alcohol and controlled-substances collection process, except calibration of evidential breath testing devices. |
| One year | Negative and cancelled controlled-substances results, MRO reversals of cancelled results as defined in Part 40, and alcohol results below 0.02. |
| While performing the function, plus two years | Education and training records for breath alcohol technicians, screening test technicians, supervisors and drivers. |
The table is a summary of FMCSA § 382.401(b), not a replacement for its full list of record types in subsection (c). DOT § 40.333 also specifies employer records and periods under Part 40. Read the applicable agency and DOT-wide requirements together, and preserve a record longer where another legal hold or valid obligation requires it. Do not shorten a retention period based solely on a software default.
Keep testing files distinct from Clearinghouse queries
The FMCSA Drug and Alcohol Clearinghouse is a separate federal database for specified CDL/CLP driver violations and query history. The FMCSA employer FAQ says Clearinghouse query history is maintained in the system, but employers must retain limited-query consent records for three years. A Clearinghouse registration or query log does not erase the employer's separate Part 382 testing-record duties.
When building the register, give “test result”, “collection record”, “training record”, “annual MIS summary” and “limited-query consent” separate categories. A positive test document and an annual query acknowledgement are not the same record and should not be filed under an undifferentiated driver upload folder. Restrict access: § 382.401(a) expressly requires secure storage and controlled access, reflecting the sensitivity of the material.
Assign a record owner and retrieval route
For each category, record the governing provision, event date, minimum end date, custodian, secure location and access group. Where a consortium or third-party administrator performs a task, establish who holds the original and how the employer will retrieve an inspectable record. Outsourcing a test process does not relieve the employer of its recordkeeping duty.
The current rule says records required by Part 382 must be available for inspection at the employer's principal place of business within two business days after an authorised FMCSA request. FMCSA confirms electronic records can be used if they can be produced for inspection under the applicable rule. Test the retrieval route before an audit: can the designated reviewer find the right signed form, result, refusal documentation or programme record without broadly exposing other drivers' files?
Do not turn this retention register into a decision about whether a driver may perform safety-sensitive work. Screening, consent, Clearinghouse queries, return-to-duty and follow-up testing have separate rules and decision points. The register should support the compliance programme, not replace it.
For the commercial workflow, assess Complys US DOT compliance software against these concrete needs: category-specific retention, restricted access, source-document retrieval and an auditable review trail. Ask for a current demonstration. This article does not claim Complys runs FMCSA testing, queries the Clearinghouse, determines fitness for duty or applies legal holds automatically.
