Best practices for collecting and structuring factual records following a major motor carrier or personal injury collision.
1. Commercial EDR & Black Box Data
Heavy commercial trucks (Class 7 and 8) record engine parameters, hard brake triggers, speed deltas, and steering angle on Engine Control Modules (ECMs) and Electronic Logging Devices (ELDs). These are vulnerable to continuous overwriting during subsequent vehicle operation.
2. Unbroken Chain of Medical Care
Document each medical provider, diagnostic MRI/CT scan date, treatment interval, and discharge summary without gaps. Insurers routinely scrutinize delays between the incident timestamp and emergency room triage.
3. Physical Scene Documentation
Record road surface conditions, skid marks, gouge marks in asphalt, traffic signal timing cycles, and nearby commercial surveillance cameras before weather or municipal paving alters the physical evidence.
