Select the characteristic that best describes the event that caused the first harm to the vehicle/occupants.
The first injury or damage-producing event that characterizes the crash type.
This element is needed for uniformity in reported motor vehicle crash statistics, understanding crash causation, and identifying possible crash avoidance countermeasures. For analytic purposes it may be desirable to collect and use information about subsequent events, some of which may be harmful. (See Sequence of Events V20)
- If First Harmful Event has a value of ‘collision with motor vehicle in transport’ or ‘collision with parked motor vehicle’, then Number of Vehicles must equal ‘2’ or more.
- If First Harmful Event indicates ‘pedestrian’ or ‘cyclist’ involvement, then at least one person involved must have a ‘non-motorist’ type code completed.
- If First Harmful Event indicated collision with a ‘parked motor vehicle’, then Vehicle Action Prior to Crash should be ‘parked’ for at least one motorized vehicle involved in the crash.
- If Manner of Collision’s value is ‘single vehicle crash’, the First Harmful Event should not indicate a collision with a motor vehicle in operation or parked.
- If First Harmful Event Location is recorded as ‘roadway’, the First Harmful Event should not indicate a collision with a ‘barrier’, ‘curb’, ‘ditch’, ’embankment’, ‘guardrail’, ‘traffic control device’, or ‘utility pole’ ‘light pole or other post/support’.

The First Harmful Event field was appropriately completed in almost 95 percent of the reports reviewed. For the reports that were deemed unacceptable, inconsistency was the issue for nearly 3 percent. Leaving the field empty occurred in 2 percent of the reports reviewed, and happened more often with local police than State Police. Finally, invalid entries occurred in just under 0.5 percent of the reports. There was an appreciable improvement for reports submitted electronically by local police since the previous audit, where this field was deemed acceptable only 87 percent of the time.
