How long does it take to stop a car at 55 mph?
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. At 30 mph, it is about half a football field.
How many feet does it take to stop at 60 mph?

Furthermore, what is the stopping distance at 25 mph? A car moving at a speed of 60 mph will travel 132 feet before the car even starts braking.
What’s the average stopping distance for a car?
If the driver is very responsive and takes only a half a second to react, the distance is reduced to 237.6 feet. Notice that the reaction time is a huge factor since it is at initial velocity. Based on pure math, it is evident that there is a very large difference in the reported performance tests and reality.
How many feet does it take to stop a truck?
A typical tractor-trailer or other large truck can weigh as much as 80,000 pounds by law. Most passenger vehicles are about 3,000 – 4,000 pounds.
