What is the rule of thumb for determining the stability of a vehicle involved in a collision?

The rule of thumb for determining the stability of a vehicle involved in a collision emphasizes the need for a thorough assessment by trained rescue personnel. This approach acknowledges that factors influencing stability can be complex and that an inexperienced observer may not take into account all necessary considerations, such as structural integrity, potential for shifting during rescue operations, or hazards related to the collision.

Rescue personnel are trained to recognize not only the visual indicators of stability but also the potential risks posed by other elements such as the terrain, the vehicle’s condition post-collision, and the presence of occupants. Thus, relying on trained personnel ensures a proper evaluation to prevent any further complications during vehicle extrication.

Simply relying on the vehicle being upright on four wheels, having the transmission in "Park", or the parking brake engaged does not guarantee stability, as these factors alone do not account for any internal damage or other dynamic risks present. Stability assessments must consider all aspects of the scenario, reinforcing the importance of professional evaluation in maintaining safety during rescue operations.
