## How long does it take to stop a car going 20 mph?

Although a car traveling at a speed of 20 mph will take about 20 feet to stop once the driver has pushed the brake pedal, a vehicle going 40 mph will require 80 feet of space to be covered before it ceases moving.

## How many seconds does it take to stop a car going 30 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.

At 55 mph, on a dry road with good brakes, your vehicle will skid approximately 170 feet more before stopping. This distance, combined with the perception and reaction distances, means you need about 300 feet to stop a car traveling at 55 mph. As a point of reference, Lambeau Field is 360 feet long, end to end.

## What is the 4 second rule while driving?

The 4 second rule’s main purpose is to ensure drivers stay at least 4 seconds behind the car in front of them. 4 seconds is proven to be the adequate distance to prevent crashes, contradicting previous estimates of 2-3 seconds.

## What is the formula of stopping distance?

Expressed in the formula: (speed ÷ 10) × (speed ÷ 10) + (speed ÷ 10 × 3). For my standard example at 100 km/h, the stopping distance under normal braking is 130 metres.
