There are seven basic areas of operating space around the vehicle. The diagram on next slide shows the six zones, areas, or spaces surrounding the car which are visible to the driver. A zone is an area of space around a vehicle that is the width of a lane and extends as far as the driver can see. The vehicle occupies the central area, or Zone 7.
The crumple zone on the front of these vehicles absorbed the collision impact. The crumple zone, also known as the crash zone, is the area in a car where the energy of the impact is absorbed and reduced, thus preventing it from being transmitted to the occupants and keeping passengers safe during accident. It is designed to crumple and deform in time of collision.
