01

Evidence that may help explain what happened

Bicycle and helmet when relevant. Signal, lighting, sight-line, and surface photographs. Witness, vehicle, report, and treatment information. 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 may not be the only relevant party; vehicle ownership, employment, products, or public roadway control may require review.
