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.
