What distance is required to stop a car traveling at 50 mph

Only then does the car begin to slow. On dry pavement that takes 4 1/2 seconds, traveling another 144 feet, but if it's wet, you'll travel 183 feet. You can do the math - it has taken about as long as a football field to stop your car at 55 mph (265 and 303 feet), and that is assuming you were alert

In order for a car to stop, it requires a max of 10ft depending on the brakes it has.
