Evidence that may help explain what happened

Inspection and crash records. Carrier, dispatch, maintenance, cargo, and electronic-data leads. Medical and work-impact documentation. Preserve originals where practical, note who created each record, and do not alter damaged property or digital files merely to make them easier to present.

02

People and organizations that may hold information

A driver, carrier, vehicle owner, shipper, broker, maintenance provider, or manufacturer may hold relevant information.
