The Location field is used to identify the characteristics of the crash with respect to its location on or off a trafficway. See a diagram of the trafficway below:
01 - Trafficway, on Road is used if the unstabilized situation (see definition for unstabilized situation in Appendix C) for this crash originated on the roadway or shoulder or at least one harmful event occurred on the roadway or shoulder.
Example 1: A motor vehicle driving on a roadway runs off the road and crashes into a tree.
Example 2: A motor vehicle driving on a roadway crosses the centerline and crashes into another motor vehicle.
Example 3: A motor vehicle backs out of a private driveway, into the trafficway, and crashes into another motor vehicle on the roadway.
02 - Trafficway, not on Road is used if the unstabilized situation (see definition for unstabilized situation in Appendix C) for this crash did not originate on the roadway or shoulder and no harmful events occurred on the roadway or shoulder.
Example 1: A motor vehicle is purposely driving entirely on the roadside (within the trafficway), runs off the roadside and crashes into a tree.
Example 2: A motor vehicle is purposely driving entirely in the median and crashes into a traffic sign.
03 - Non-Trafficway is used if both of these conditions apply:
(1) the unstabilized situation (see definition for unstabilized situation in Appendix C) originated outside the boundaries of the trafficway and
(2) no harmful event occurred within the boundaries of the trafficway.
Example 1: A motor vehicle is driving in a parking aisle (outside the trafficway) and crashes into a parked motor vehicle.
Example 2: A motor vehicle is driving on a dirt trail (not a recognized trafficway), and overturns.
