Separate the participants
Identify the driver, vehicle owner, carrier, shipper, broker, maintenance provider, employer, and insurer where possible. A logo alone does not prove the relationship.
Ask about records
Electronic logs, dispatch data, route records, inspections, maintenance, cargo documents, training, and onboard video may help reconstruct an event.
Seek timely local advice
Commercial evidence and legal duties vary. Ask an Injury Law Firm which records warrant prompt preservation and which law applies.
