The time you take to begin braking here will be your reaction time, with your reaction distance that of the time your examiner slaps the dashboard to the time you initially apply the brakes, Once again, if you’re a fully experienced driver in a familiar car, your reaction distance should be around 0,7 seconds, with the less experienced or impaired driver in an unfamiliar vehicle looking at 1,5 seconds plus,
Cars With the Best and Worst Braking Distances
Braking Distance
Braking Distance, The braking distance is the distance that a vehicle travels while slowing to a complete stop, The braking distance is a function of several variables, First, the slope grade of the roadway will affect the braking distance, If you are going uphill, gravity assists you in your attempts to stop and reduces the braking distance, Similarly, gravity works against you when you are
Braking distance depends on how fast a vehicle is travelling before the brakes are applied, and is proportional to the square of the initial speed, This means that even small increases in speed mean significantly longer braking distances, Braking distances are much longer for larger and heavier vehicles, and in wet or icy conditions,
| Speed | Thinking + braking distance | Stopping distance |
| 20mph | 6m + 6m | 12m 40 feet |
| 30mph | 9m + 14m | 23m 75 feet |
| 40mph | 12m + 24m | 36m 118 feet |

Audi once again graces our list with the same braking distance of 101 feet this time in the form of the 2014 Audi RS7,
This parameter is substituted into the following formula, Braking distance = the square of the speed in kilometers / hour divided by the coefficient of friction multiplied by 250, If the car is moving at a speed of 50 km / h, then according to this formula, the braking distance is already 12,5 meters,

Brake Friction
Data is being collected on two cars to test their safety Below are two graphs that represent the two different cars Each graph shows the thinking distance of each driver and the braking distance of each vehicle and how they change with different initial velocities The safer car will slow down in a shorter time once a driver has applied the brakes,

Car braking distance
Braking Distances of Cars A random sampleof 13 four-cylinder cars is obtained and the breaking distances are measured and found to have a meanof 137,5 ft and a standard deviationof 5,8 ft A random sample of 12 six-cylinder cars is obtained and the braking distances have a mean of 1363 ft and a standard deviation of 9,7 ft, Use a 0,05 significance level to test the claim that braking
So for a fixed maximum braking force, the braking distance is proportional to the square of the velocity, Example thinking distance calculation A car travels at 12 m/s,
