When FMCSA or state enforcement requests driver qualification records, the rules define what each file must contain and how carriers must make records available—not a single checklist printed inside Part 391.
Short answer
Maintain a § 391.51 qualification file for each employed driver with the application, MVRs, road test evidence, annual MVR and review note, medical certification, and related items listed in the rule. Keep investigation history separately under § 391.53. You may store records at your principal office or other locations, but must produce them within 48 hours at a place the investigator specifies. Legible copies satisfy § 390.31 unless a section requires originals. DQid organizes status and dates; carriers remain responsible for completeness and production.
Records investigators expect in the qualification file
Core § 391.51 contents
49 CFR 391.51(b)Application (§ 391.21), initial MVRs (§ 391.23), road test certificate or accepted equivalent (§§ 391.31, 391.33), annual MVR and review note (§ 391.25), medical certification or CDLIS record (§§ 391.43, 391.23(m)), and variances or SPE documents when they apply.
Separate investigation file
49 CFR 391.53Prior employer safety performance history and alcohol or drug consent belong in the secured investigation history file, available to authorized representatives on request.
Clearinghouse query records
49 CFR 382.701(e)Retain three years of query records for drivers subject to Part 382 testing.
Location and production timing
Where files may sit
49 CFR 390.29(a)Multi-location carriers may keep subchapter records at the principal office, a regional office, or a driver work-reporting location unless another section specifies otherwise.
48-hour availability
49 CFR 390.29(b)Records kept away from the principal office must be available for inspection at the principal office or another location the agent names within 48 hours (excluding Saturdays, Sundays, and Federal holidays).
Copies
49 CFR 390.31Legible copies may be maintained instead of originals when the rule does not require the original document.
Practical preparation carriers control
Index drivers by name and employment status, tie each checklist item to a dated document, and confirm annual MVR, Clearinghouse, and medical cycles before a request arrives. Internal sampling—opening files at random—surfaces gaps earlier than an external review.
DQid shows missing items and review states; it does not predict enforcement outcomes or replace your retention policy.
