How do you measure braking distances?
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.
What is the normal stopping distance of a car?
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 average deceleration of a car?
between 1.1 and 2 m/s2
Normally, average deceleration rates of light vehicles are between 1.1 and 2 m/s2, although a maximum value of 3.09 m/s2 is achievable [1].
What is the typical braking distance from 50 mph?

What is the stopping distance for a car at 50 mph?
Stopping Distance: Is The Highway Code Wrong?
Speed | Stopping Distance |
---|---|
30mph | 23 Meters / 75 Feet |
40mph | 36 Meters / 118 Feet |
50mph | 53 Meters / 175 Feet |
60mph | 73 Meters / 240 Feet |
How is braking distance affected by speed?
How Speed Effects Braking Distance. The faster you drive the longer it takes to stop. This means speeding increases your stopping distance and force of impact. If you double your speed then your stopping distance and force of impact are 4 times greater.
What is the typical stopping distance at 50 mph?
At 50 mph, the typical thinking distance will be 15 metres (50 feet), plus a braking distance of 38 metres (125 feet), giving an overall stopping distance of 53 metres (175 feet). The stopping distance could be greater than this, depending on your attention and response to any hazards.
What is the stopping distance at 20 mph?
At 20 mph during perception and reaction time, a vehicle will travel 45 feet (30 feet per second x 1.5 seconds). Once the brakes are applied, it takes approximately 19 feet to come to a stop, for a total distance of 64 feet.
How many Gs can a car accelerate?
Maximum vehicle acceleration depends on tires and horsepower. Top of the line production muscle cars can go from 0 to 60 mph in 5 seconds. Average acceleration is 60 mph per 5 seconds which equals 12 mph per second and equates to +0.55 g’s….Acceleration Parameters.
