# DQ File Transfer in Carrier Acquisition / Merger

When a carrier acquires another carrier, the driver qualification files transfer with the driver. The acquiring carrier inherits responsibility for verifying records.

## Permitted transfer methods
1. **Original files transferred** physically (or digitally) at acquisition
2. **Acquired carrier provides documents** for the acquiring carrier to create new DQFs

The acquiring carrier becomes responsible from the acquisition date forward. Prior period responsibility stays with the prior carrier's records.

## Required verification by acquiring carrier
- All 12 documents present (per § 391.51)
- Documents are current (not expired)
- Documents are properly executed (signatures, dates)
- Driver's safety performance history covers the acquiring period if needed

## Common gaps in inherited DQFs
- Missing prior-employer inquiries for older hires
- Missing road test certificates for drivers hired before § 391.31 was clarified
- Medical examiner verification missing for pre-2014 drivers (National Registry didn't exist)
- ELDT certificates missing for drivers with CDLs predating 2/7/2022 (exempt — note in file)

## Inheriting non-DOT drivers
If acquiring a carrier with both DOT and non-DOT drivers (e.g., property-only intrastate), only the DOT-qualified drivers need DQFs under federal rules. State rules may differ.

## Reporting obligations
- Acquiring carrier inherits the prior carrier's DataQ-eligible inspection history
- Acquiring carrier inherits CSA score (50% of acquired carrier's score weight typically merges per FMCSA SMS rules)
- File FMCSA Form MCS-150 within 30 days of acquisition

## Remediation steps for incomplete DQFs
- Document the gap (note "inherited file — document not available from acquired carrier")
- Re-create what you can (re-pull MVRs, re-do prior employer inquiries)
- Update medical exam if current cert has passed
- The acquiring carrier cannot be cited for the prior carrier's documentation gaps, but YOU must remediate from date of acquisition forward

## Best practice
Audit each acquired DQF within 60 days of acquisition. Set up the acquired carrier's drivers in your Compass DQ Files module — Compass scans for missing slots and surfaces remediation actions.

## CFR citations
- **49 CFR § 391.51**
- **49 CFR § 390.21**

## How Compass surfaces this
This skill is searchable in Compass Ask and runs against the carrier's actual fleet data when invoked from the relevant tracker. Read-only; no actions taken without explicit user approval.
