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

Stopping distances at different speeds.
| Speed | Thinking + braking distance | Stopping distance |
|---|---|---|
| 70mph | 21m + 75m | 96m (315 feet) |

What is the stopping distance at 75 mph?
Therefore, if you are driving 75 mph, it will take you approximately 356.25 feet to stop your car.
Will the stopping distance be less if he travels at 70 mph or at 80 mph?
Increasing kinetic energy also increases stopping distance. Increasing the speed limit to 80 mph would increase the average stopping distance on motorways to 120 metres (30 car lengths!), a 25% increase on the 96 metre stopping distance found at 70 mph.
What is 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. ... Braking Distance – The distance a vehicle travels from the time a driver begins pressing on the brake pedal until the vehicle comes to a 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 is the recommended minimum stopping distance for a car?
Keeping a Safe Stopping Distance
You should be at least two seconds behind in perfect conditions (on a dry road surface with good quality tyres and well-maintained brakes). Leave an even greater distance behind the car in front of you if the conditions aren't perfect.
What is the minimum stopping distance?
For calculating minimum stopping distance, a value of 0.8 is a nominal value for the coefficient of static friction between good tires and a good road surface. Generally, coefficients of kinetic friction are less, and may be dramatically less for wet, icy, or oily surfaces.
How long does it take to stop at 80 mph?
At 80 mph, braking distance goes up to 305 feet, almost double the breaking distance at 60 mph. Including distance traveled during perception and reaction time of 180 feet results in a total stopping distance at 80 mph of 485 feet.
Is driving 80 mph bad for your car?
Frequently driving over 80 mph is incredibly risky and it can also take a toll on your vehicle. True, most modern cars have higher maximum speeds and are even designed to go as fast as possible. However, frequently pushing your car to its limits puts unneeded stress on the engine and transmission.
How long does it take to stop from 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 long does it take for a car to stop at 60 mph?
A vehicle traveling at 60 mph covers 88 feet per second. But stopping that vehicle takes over 4.5 seconds and covers a distance of 271 feet. Why? Because there's more involved in braking than the actual time your brakes are applied to the wheels (called "effective braking").
