If you are in good mental and physical condition, what is your vehicle’s reaction distance when traveling at 40 mph?

If you are in good mental and physical condition, your vehicle’s reaction distance when traveling at 40 mph should be: 83 feet

This also defines the recommended distance that you should maintain from another vehicle when you're traveling at 40 mph. It is important to maintain this distance because when you hit the brakes, your car need some time to accelerate down before it hit the speed of 0.
