Crash Investigations Class 315 Practice Test

The key idea is using a multi-source approach at the scene to identify anyone affected beyond the vehicle’s occupants. Thorough scene assessment and proper traffic control help preserve evidence and reveal all victims, and prompt medical or coroner notifications flag potential fatalities quickly. Then you verify and enrich that information by cross-checking with witnesses who saw what happened and with available data from equipment and records—such as surveillance footage, traffic cameras, on-scene sensors, and EMS or hospital reports. This combination ensures pedestrians, cyclists, or bystanders who were struck are identified, even if they weren’t inside a vehicle or didn’t appear clearly in vehicle data. Relying only on the vehicle’s black box data misses non-occupants; simply counting people at the scene isn’t reliable for identifying injuries or fatalities; and a driver’s license database won’t reveal non-occupants involved in the crash.
