## How do you use the 4 second rule?

You should apply the four-second rule when it’s wet, frosty or when you are towing a trailer. The four-second rule means that you leave four seconds between you and the vehicle in front. It gives you more time to react and more time to stop.

## How do you calculate the stopping distance?

All you need to do is multiply the speed by intervals of 0.5, starting with 2. That’ll give you the stopping distance in feet, which is acceptable for the theory test. For example… There are 3.3 feet in a metre – so divide the distance in feet by 3.3 to get the stopping distance in metres.

## How do you calculate braking and stopping distance?

Thinking distance + Braking distance = Stopping distance Your thinking distance is the distance your car travels after you have spotted a danger, before you apply the brakes.

## What is stopping distance of a vehicle?

Imagine that a car is travelling on a straight road. The driver sees a problem on the road ahead and so brakes suddenly to stop. The stopping distance is the distance that the car travels from the moment that the brakes are applied to the moment that the car stops. This is also called the braking distance.

## How many car lengths is a safe distance?

What is a safe distance between cars? For approximately every 30kmh of speed, following distance should be two car lengths. At around 60kmh, following distance should be four car lengths.

## What is the minimum stopping distance at 70mph?

If you’re travelling at 70mph, the stopping distance will be more like 24 car lengths.

## How many feet does it take to stop at 60 mph?

Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances.

## How many feet does it take to stop at 35 mph?

136 feetAt 30mph the stopping distance is much greater—109 feet. At 35 mph it goes up to 136 feet, and you’re not really speeding yet. Switch up the numbers to freeway speeds—60 mph has a stopping distance of around 305 feet. That’s the length of an entire football field to stop.

## How many car lengths is 2 seconds?

The two-second rule is useful as it works at most speeds. It is equivalent to one vehicle- length for every 5 mph of the current speed, but drivers can find it difficult to estimate the correct distance from the car in front, let alone to remember the stopping distances that are required for a given speed.

## How many car lengths should be between cars?

Figure one car length for every ten miles an hour,” Barndt said. “So if you’re doing 55 miles an hour you should have six car lengths between you so that if something happens to the car in front of you, you have time to stop or react.” The number two item Barndt says drivers are all guilty of is being distracted.

## How far does a car travel in 1 second?

Originally Answered: How far does a car travel in 1 second at 30 mph? 30 mph is 30 miles in one hour, or 30 x 1760 yards in 3600 seconds. So in one second you will travel 14 2/3 yards.

## What is the definition of total stopping distance?

Total stopping distance is the distance your vehicle travels from the time you see a hazard and press on the brake until the vehicle stops. Total stopping distance is made up of three parts: … The distance your vehicle travels while you react is called a reaction distance.

## How do you calculate the stopping distance of a vehicle?

Formula: Remove the zero from the speed, multiply the figure by itself and then multiply by 0.4. The figure 0.4 is taken from the fact that the braking distance from 10 km/h in dry road conditions is approximately 0.4 metres. This has been calculated by means of researchers measuring the braking distance.

## What is the stopping distance in rain?

When driving in wet conditions or in rain the Highway Code advises your total stopping distance will be at least double the distance to stop on a dry surface.
