Including first and most harmful
The events in sequence related to each specific motor vehicle, including both non-collision and collision events.
First Harmful Event:
The first event that results in any level of injury or damage. Location of the First Harmful Event is the location of the object being struck resulting in the first injury or damage. For example, if striking a concrete barrier is the First Harmful Event, then the location of the concrete barrier would be the location of the First Harmful Event. Fixed objects are not normally installed on road shoulders, so the location of First Harmful Event for a collision with a concrete barrier would not be the road shoulder.
Most Harmful Event:
Event that resulted in the most severe injury or, if no injury, the greatest property damage involving that motor vehicle. The Most Harmful Event must be in the sequence of events.
Sequence of event:
Listing in sequential order of events involved with the crash. If more than four events occurred, then duplicate events and non-harmful events are removed first in order to reduce the total number of entered events to four.
Non-damage or injury producing events
These events do not cause damage or injury. These events cannot be entered as the First Harmful Event or Most Harmful Event.
Damage or injury producing events
These events must cause damage or injury to be included in the sequence of events. These are the only events codes that can be used for the First Harmful Event and Most Harmful Event. Codes 40 through 69 are normally not the first event in the sequence of events, as these items are not installed in the roadway. As such the vehicle would have a first event of “01 – Ran Off Road Right,” for example, prior to hitting the concrete barrier or mailbox.
