Commercial Truck Incident Evidence & Spoliation Timeline
Organize physical, telematics, regulatory, and police records for serious heavy-vehicle collisions. Track automatic ECM/dashcam overwrite deadlines (49 CFR FMCSR rules) and generate a ready-to-serve formal Spoliation Demand Packet.
ECM / EDR "Black Box" Volatility
Modern class-8 commercial tractors (Freightliner, Peterbilt, Kenworth, Volvo) record critical trigger events (sudden deceleration, hard brake, lane departure). If the truck is driven or battery cycled, subsequent non-critical brake incidents can purge the event freeze-frame data within 30 to 60 days.
FMCSR Statutory Retention Limits
Under Federal Motor Carrier Safety Regulations:
- 49 CFR § 395.8(k): Electronic Logging Devices (ELD) & driver logs are required to be kept only 6 months.
- 49 CFR § 396.11: Driver Vehicle Inspection Reports (DVIR) only need to be retained for 90 days.
- 49 CFR § 382.401: Post-crash drug/alcohol testing must be administered within 2 to 32 hours.
Spoliation Sanctions Under Texas & Federal Law
Once a motor carrier receives a detailed, formal written notice specifying impending litigation and itemizing electronic files, their common-law duty to preserve triggers. Subsequent failure to freeze automatic deletion routines can support adverse-inference jury instructions.
