Stopping Distance
When the time comes to stop your vehicle, either under normal circumstances or for an emergency, everything is related
to the speed you are traveling at. If you are speeding it is going to take you longer to decelerate. When the amount of
time it takes to bring your vehicle to a stop increases so does the distance. The stopping distances may surprise you.
| SPEED | STOPPING DISTANCE | TOTAL STOPPING DISTANCE | |
| MPH | Feet | (Plus 3/4 of a second reaction time) Feet |

| 10 | 5 | 11 | 16 |

These results are under normal conditions. They are dramatically increased by a number of factors. Such as the weight of the
vehicle, the condition of the brakes and tires, the surface type, and the experience level of the driver among other factors.
The numbers above tell you everything about how your speed effects the distance it will take you to stop your vehicle.
The distances added from reaction time alone are important to note. Your reaction time may be faster than 3/4 of a
second when you're at your best but it can be much longer if you're tired or otherwise impaired. This only adds to
the total stopping distance.
