Definition: Work Zone Crash

Work Zone Crash - a traffic crash in which the first harmful event occurs within the boundaries of a work zone or on an approach to or exit from a work zone, resulting from an activity, behavior or control related to the movement of the traffic units through the work zone. Includes collision and non-collision crashes occurring within the signs or markings indicating a work zone or occurring on approach to, exiting from or adjacent to work zones that are related to the work zone.

For example:

1. An automobile on the roadway loses control within a work zone due to a shift or reduction in the travel lanes and crashes into another vehicle in the work zone.
2. A van in an open travel lane strikes a highway worker in the work zone.
3. A highway construction vehicle working on the edge of the roadway is struck by a motor vehicle in transport in a construction zone.
4. A rear-end collision crash occurs before the signs or markings indicating a work zone due to vehicles slowing or stopped on the roadway because of the work zone activity.
5. A pickup in transport loses control in an open travel lane within a work zone due to a shift or reduction in the travel lanes and crashes into another vehicle which exited the work zone.
6. A tractor-trailer approaching an intersection where the other roadway has a work zone strikes a pedestrian outside the work zone because of lack of visibility caused by the work zone equipment.

Excludes single-vehicle crashes involving working vehicles not located in trafficway.
For example:

1. A highway maintenance truck strikes a highway worker inside the work site.
2. A utility worker repairing the electrical lines over the trafficway falls from the bucket of a cherry picker.
