content: This small slide chart allows motorists to find their “danger zone,” that is to say the distance an automobile will move forward in feet after a motorist wishes to stop, as this varies with the speed of the car (ranging from 20 to 80 miles per hour) and the reaction time of the driver (ranging from 1/4 second to 1 second). The total stopping distange or “danger zone” ranges from 29 feet to 469 feet.
