What is an example of a high mechanism vehicle collision?

1. A crash into a stationary object

2. A rollover with possible death at the scene

3. A rear-end collision at low speed

4. A parking lot fender bender

The correct answer is: A rollover with possible death at the scene

A rollover with possible death at the scene is an example of a high mechanism vehicle collision because it involves significant force and potential for severe injury. High mechanism collisions are characterized by the energy produced in the crash, which typically results from high speeds, significant impact angles, or complex vehicle dynamics, such as rollovers. Rollover incidents often suggest that the vehicle has flipped over or experienced multiple impacts, contributing to a higher risk of serious injury or fatality. Other options such as a crash into a stationary object, a rear-end collision at low speed, and a parking lot fender bender generally involve lower energy impacts and are less likely to result in severe injuries compared to rollovers. They may not exhibit the same level of catastrophic potential that defines high mechanism collisions, as they often occur at reduced speeds or involve minimal impact force.
