What is an indicator of an un-stabilized traffic incident?

An indicator of an un-stabilized traffic incident is the involvement of a motor vehicle in transport. This suggests that the situation is dynamic and ongoing, meaning that the vehicles are still moving or at risk of moving, which can create additional hazards for responders and other road users. In contrast, a stabilized incident typically involves vehicles that have come to a stop or have been moved to a safe location, where the potential for further conflict or danger has been minimized.

The other options do not necessarily imply that the incident is un-stabilized. For instance, if there are no injuries or damages reported, it might indicate that the situation isn't critical. Similarly, stationary vehicles would suggest that the incident is under control, and an occurrence in a parking lot often indicates that the potential for further complications is limited, as opposed to a busy roadway. These scenarios typically represent a stabilized environment rather than an ongoing or chaotic condition.
