When determining the stability of a vehicle involved in a collision, what is the general rule of thumb?

The statement that a vehicle should only be considered stable after assessment by trained rescue personnel is accurate because it emphasizes the importance of a professional evaluation in ensuring safety. Following a collision, the structural integrity of the vehicle can be compromised, leading to potential hazards such as shifting weight, uneven ground, or hidden damage that could cause the vehicle to change position unpredictably.

Trained rescue personnel possess the knowledge and skills necessary to evaluate the risks associated with the vehicle's condition, using techniques and tools to stabilize it safely before any extrication or movement. This careful assessment is essential to prevent further injuries to any victims inside the vehicle and to protect rescuers from unexpected incidents.

The other suggestions imply either a false sense of security about the vehicle's stability or an approach that could lead to unnecessary risk, demonstrating why a trained assessment is crucial in these scenarios.
