Workplace Accident Investigation Training

When a crash occurs, the carrier's investigation matters for: insurance claim, FMCSA Crash Preventability Determination Program, lessons learned, regulatory response. Train someone in your fleet to do this.

Investigation steps

1. Within 24 hours: secure documentation (police report, photos, dashcam footage, ELD data, driver statement)
2. Within 7 days: interview driver + witnesses
3. Within 14 days: technical analysis (vehicle condition, equipment failure investigation)
4. Within 30 days: written summary (preventability assessment, lessons learned)

What to look for

• Police report details
• Citations issued (if any)
• ELD data leading up to crash
• Dashcam footage
• Vehicle inspection of involved unit
• Weather + road conditions
• Driver's HOS status
• Driver's history (prior crashes, violations)
• Mechanical condition of vehicle

Preventability assessment

• Driver had reasonable opportunity to avoid crash → Preventable
• Driver had limited reasonable opportunity → Possibly preventable
• Driver had no reasonable opportunity → Not preventable

This determination supports the FMCSA Crash Preventability Determination Program filing.

When to escalate

• Fatal crash → outside expert immediately (insurance, attorney, expert witness)
• Multi-vehicle pile-up → outside expert
• Hazmat release → outside expert + regulatory notification
• Conflicting accounts → outside expert
• Significant property damage → outside expert

Internal investigator qualification

• Experience handling crashes (not first investigation)
• Understanding of CMV operations
• Familiarity with FMCSA regulations
• Photography + documentation skills
• Interview skills
• Written report writing

Documentation retention

• All investigation materials retained per FMCSA 1-year + 6 months rule (vehicles + accidents)
• Insurance claim copies retained as long as insurer requires
• Settlement records retained per state statute of limitations
