What is a Driver Qualification (DQ) file?
The DQ file is the per-driver compliance dossier required under 49 CFR §391.51. It holds the §391.23 pre-employment investigation, every §391.25 annual MVR review and the company official's written review note, the medical certificate, the road-test certification, the §391.27 list of violations, and the application for employment. Auditors pull DQ files before they pull anything else.
The DQ file is regulatory recordkeeping, not just a manila folder. §391.51 enumerates the items that must be in it and the retention periods for each. The application for employment, the previous-employer inquiry response, the road test (or accepted equivalent), the medical certificate, the MVR + CDLIS + PSP from the §391.23 packet, and the certificate of investigation by the company official all live in the DQ file from hire forward.
During employment, every §391.25 annual review adds a fresh MVR plus the company official's one-paragraph written review note. Every §391.27 driver certification of violations (annual self-disclosure) goes in too. Every medical certificate renewal replaces the prior one and the DQ file keeps the past one for the §391.51(c)(3) retention window.
After termination, §391.51(c) sets retention periods. The general rule: keep the DQ file for three years from termination. Some items have separate retention periods — pre-employment drug test results live separately under §382.401.
During an FMCSA compliance review, the auditor typically samples 10-30 driver files at random and works through the §391.51 checklist on each one. A DQ file with consistent paperwork on every item is a clean review; gaps are written up as violations and assessed against the carrier's SMS BASIC scores. The optional FastDriverScreening DQ File template ($25) is a fillable PDF + editable Word version that pre-formats the §391.51 checklist for each driver.
