"Proper Space Management" means maintaining enough space around your vehicle to operate and stop safely. To stop your vehicle safely, several factors come into play. "Perception distance" is the distance a vehicle travels from the time you see a hazard until your brain recognizes the hazard. For an alert driver, about 3/4 of a second; but at 55 mph, your vehicle travels some 60 feet in that 3/4 of a second.
"Reaction Distance" is the distance a vehicle travels from the time the driver’s brain tells him to move his foot from the fuel pedal to the brake pedal. Again, 3/4 of a second for the alert driver; again at 55 mph another 60 feet traveled. Then, you add in brake lag and braking distance and you see why a safe cushion is necessary to avoid a rear-end accident. In ideal conditions, at 55 mph, it will take a total of 6 to 7 seconds to stop and your vehicle will travel about 290 feet. At higher speeds, the stopping distance will increase. A safety cushion of 6 to 7 seconds is the answer to avoid a rear-end accident along with the fines, costs and court drama that go along with it.
A rear-end collision is one of the most embarrassing accidents you can have!
