Record the events of the crash in chronological order, specific to the vehicle. Select which event was the most harmful. NOTE: The sequence of events boxes are used to describe what occurred during the crash. In order to account for complex scenarios, you may enter up to four events per vehicle. If there are more than four events, record the four most significant events. The sequence of events codes are grouped into two categories, including non-collision (i.e. ran-off road and rollover) and collision with objects (i.e. motor vehicle, light poles and trees).
The Sequence of Events are events related to this motor vehicle, including non-harmful events, non-collision harmful events and collision events recorded in chronological order. Most Harmful Event is the event that resulted in the most severe injury or, if no injury, the greatest property damage involving this motor vehicle.
Both vehicle event fields, Sequence of Events and Most Harmful Event, are important for use in conjunction together, along with Vehicle Action Prior to Crash in order to generate complete information about the crash.
- If Sequence of Events indicates involvement with a ‘pedestrian’ or ‘cyclist’, then at least one non-motorist person type must be entered.
- If Sequence of Events includes collision with a motor vehicle either ‘parked’ or ‘in transport’, then there must be at least two vehicle entries in the crash.
- If Sequence of Events contains only one value, then the value for Most Harmful Event for the motor vehicle must be the same.
- If Sequence of Events indicates ‘cross median/centerline’, then the Trafficway Description should not be ‘one-way’.

The Sequence of Events field was the field in the vehicle section of the report that had the third highest frequency of unacceptable information, at 90 percent. Most often, the issue was an inconsistency with other information in the crash report. State Police had a slightly higher percentage of inconsistencies than either submission type by local police. This field often had only one or two options completed, when other information on the report indicated additional information. Law enforcement auditors shared their view that officers found this field confusing, and additional information on how it should be used would be helpful. The Most Harmful Event field was completed appropriately in 94 percent of the reports reviewed. The field was found to be inconsistent with other portions of the crash report in 4 percent of reports audited, was left empty in more than 2 percent of reports, and was deemed invalid in 0.2 percent. This data shows a 4 percent increase in acceptable reports when compared to the 2008 audit. Auditor findings indicated that the challenge with this field was determining how to single out which event was most harmful, acknowledging that a series of crash events may have different interpretations. When more than one serious action has occurred, officers stated that it becomes difficult to determine which event would be the most harmful.
