The first thing you should do when you come upon a vehicle that is overturned is to?

When encountering an overturned vehicle, the most critical first step is to stabilize the vehicle. Stabilization is essential to ensure the safety of both the responders and any occupants inside the vehicle. An overturned vehicle poses several dangers, including the risk of it rolling further, collapsing or shifting, which could jeopardize the lives of those trapped inside and rescue personnel.

Stabilizing the vehicle involves using equipment such as wheel chocks, stabilization struts, or ropes to prevent movement. This ensures that the scene remains safe while you assess the situation and plan further actions, such as safely accessing the vehicle or extricating the occupants.

Addressing the other choices, gaining access through a window or pulling occupants through a rear window can pose significant risks if the vehicle is not stabilized first, as these actions could lead to further injury or complications. Turning the vehicle right side up may also risk shifting and causing harm if not done in a controlled and safe manner after the vehicle has been stabilized. Prioritizing stabilization helps create a secure environment for both the rescuers and the victims, allowing for a safer and more effective rescue operation.
