DataQ Evidence Standards — What Actually Wins

Not all DataQ challenges succeed. The difference is evidence quality.

High-success patterns (>70% reversal rate)

1. Identity error — wrong driver named (95% success)
2. Officer documentation error — inspection time conflicts with ELD (78% success)
3. CFR provision mismatch — citation references wrong rule (65% success)
4. Crash classification — § 390.5 trigger absent (70% success)
5. Equipment misidentification — wrong unit number (75% success)
6. Driver was hired by another carrier at time of inspection (90% success)
7. Cab card vs registration mismatch — paperwork issue clarified (60% success)
8. State law conflict with FMCSA regulation (case-by-case)

Low-success patterns (<30% reversal rate)

1. Officer made a legal interpretation error — challenging legal judgment (15%)
2. Officer was over-zealous — subjective claim (10%)
3. First-time offense argument — not grounds for reversal (0%)
4. Driver was tired — driver state isn't a defense (10%)
5. Driver was new — training isn't a defense (5%)
6. Equipment failure — should have been caught in pre-trip (15%)

Evidence ranked by power

1. Document with officer signature (highest)
2. ELD/GPS data with timestamp (very high)
3. Vehicle photo with date/timestamp (high)
4. Dispatch records (high)
5. Driver statement (medium — corroboration needed)
6. Witness statement (medium)
7. Pre-trip inspection log (medium)
8. Maintenance records (medium)
9. Photos from after-the-fact (low — no timestamp)
10. Verbal account from driver (lowest)

How to structure the challenge

1. Issue: State exactly what's wrong (1 sentence)
2. CFR citation: Reference the specific section being challenged
3. Evidence: Numbered list of documents attached
4. Timeline: What happened, in chronological order
5. Conclusion: Why the inspection record should be reversed

When NOT to file

If you have no documentary evidence and only the driver's word — the challenge is unlikely to succeed. Save the effort.

Compass automation

Compass DataQ module rates each inspection for contestability before you file:

• Win probability estimate (based on pattern match)
• Required evidence checklist
• Auto-pull of available data (ELD, GPS, dispatch)
• Drafts the challenge narrative
• You review + submit

CFR citations

• 49 CFR Part 385 Subpart D
• Compass DataQ Win-Rate Analysis

How Compass surfaces this

Searchable in Compass Ask. Runs against the carrier's actual fleet data when invoked from the relevant tracker. Read-only; no actions without explicit user approval.
