DQ Files & 49 CFR Part 391 Compliance

A Driver Qualification (DQ) file is the §391.51 packet every motor carrier must keep on every commercial driver. It contains the employment application, road test, MVR review, drug & alcohol consent, prior-employer verification, and annual review (the driver-certification of violations under former §391.27 is optional since 2022).

FMCSA new-entrant and compliance-review audits start with the DQ file. A missing §391.21 application, a stale §391.25 annual review, or a gap in the §391.23 prior-employer investigation drives most §391-related violations cited in audit reports.

The compliance cluster below covers what each §391 subsection requires, when to refresh each document, which states impose extras (medical-card upload, intrastate variances), and how to convert the paper packet into an audit-ready digital DQ file.

Companion artifacts: a $25 fillable DQ File template at checkout that mirrors §391.51 line-for-line, plus reusable consent forms that satisfy DPPA + FCRA disclosure requirements without separate paperwork per state.

For carriers running at scale, the §391.25 annual review and the §382.701(b) Clearinghouse annual limited query are the two items that tend to drift first - both have hard annual cadences and both are commonly cited in failed audits (the §391.27 List of Violations that used to sit alongside them was removed in 2022).
