Braking distance is the time it takes for your car to come to a complete stop after you’ve hit your brakes. When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four.
What is a good braking distance?
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.
What is vehicle braking distance?
Braking distance is the distance it takes to stop your vehicle once you apply the brakes.
What is the average effective braking distance time?
The average driver has a reaction time of 3/4 second. This accounts for an additional 60 feet traveled at 55 mph. Braking Distance is the distance it takes to stop once the brakes are applied. At 55 mph on dry pavement with good brakes, it can take a heavy vehicle about 170 feet and about 4 1/2 seconds to stop.
How do you calculate the stopping distance of a car?
Stopping distance = thinking distance + braking distance
Thinking distance is approximately 1 foot for every mph you travel at, for example, a car travelling at 30mph will travel 30 feet before the brakes are applied.
What cars have the best stopping distance?

| Chevrolet Camaro 2SS | 112 |
| Audi TT 2.0T | 113 |
Which car has the shortest braking distance?

How does speed impact driving distance?
Braking distance is the time it takes for your car to come to a complete stop after you’ve hit your brakes. When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four.
Does braking distance increase speed?
A Vehicle’s Braking Distance Changes with Speed
There is a direct relation to speed, and when your car will actually come to a complete stop once you hit the brakes. The time it takes the car to stop after hitting the brake is the actual braking distance, and it changes with each increase in speed.
How does speed affect braking distance?
The braking distance also depends on the speed of the car, the mass of the car, how worn the brakes and tyres are, and the road surface. … A faster speed increases both thinking and braking distance, increasing the total stopping distance.
How do you calculate brake distance?
Formula for calculating the braking distance.
The following formula has proven to be useful for calculating the braking distance: (Speed ÷ 10) × (Speed ÷ 10). At a speed of 100 km/h the braking distance is therefore a full 100 metres..
When should you use stab braking?
Stab braking: Use only on vehicles without anti-lock systems.
- Apply the brake all the way.
- Release the brakes when the wheels lock up.
- As soon as the wheels start rolling, put on the brakes fully again. (It can take up to 1 second for the wheels to start rolling after you release the brakes.
How do you reduce braking distance?
Let’s have a look at these 10 things that can help you do that.
- Tap on speed. Stopping distance is largely divided into two types — thinking distance and braking distance. …
- Maintain brakes. …
- Tyre pressure. …
- Uneven tread wear. …
- Tyre quality. …
- Road conditions. …
- Road view. …
- Distractions.
How many car lengths is a safe distance?
The rule of thumb is to maintain at least a three-second following distance, giving you time to react and avoid potentially dangerous situations. You can calculate this by using a fixed object, such as a pole or an overpass to determine how far in front of you the car is.
