Quick checklist
- Create a DQ file for each driver before dispatch.
- Use 49 CFR 391.51 as the control list for core DQ file contents and retention.
- Save the driver application and employment history items.
- Keep required MVR and safety performance inquiries where applicable.
- Track medical qualification documents.
- Complete and save annual review materials.
Why this matters
A DQ file shows that the carrier checked whether the driver was qualified to operate. Under 49 CFR 391.51, the file also has specific retention expectations, so weak onboarding can become a records problem later.

Common gaps
