What are the three main factors impacting the outcome of a crash?

The three main factors impacting the outcome of a crash are vehicle size, speed, and point of impact.

Vehicle size is significant because larger vehicles often have more mass, which can translate to a greater force in a collision. Heavier vehicles may also offer more protection to their occupants than smaller ones. Speed is crucial as it greatly affects the energy involved in a crash; higher speeds result in more severe impacts and can lead to more severe injuries. The point of impact is also critical because it determines which parts of the vehicle and occupants absorb the forces during a collision. Different points of impact can result in varying levels of damage and injury potential, depending on whether it's a frontal, side, or rear collision.

Together, these factors play a vital role in determining the severity of a crash and the resultant injuries to passengers. Understanding these elements helps in assessing risks and formulating strategies for effective child passenger safety measures.
