## 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 stopping distance at 30mph?

Stopping Distance: Is The Highway Code Wrong?

Speed | Stopping Distance |
---|---|

20mph | 12 Meters / 40 Feet |

30mph | 23 Meters / 75 Feet |

40mph | 36 Meters / 118 Feet |

50mph | 53 Meters / 175 Feet |

## What is meant by stopping distance?

: the distance that a driver needs in order to safely bring a vehicle to a complete stop.

## What does total stopping distance include?

Total Stopping Distance is the sum of the perception distance, reaction distance and braking distance. Once a driver perceives a need to slow or stop, a small amount of time passes. The time it takes to react and come into the correct braking position is the reaction distance.

## What is the stopping distance at 70?

Driver Care – Know Your Stopping Distance

Speed | Perception/Reaction Distance | Braking Distance |
---|---|---|

50 mph | 73 feet | 125 feet |

60 mph | 88 feet | 180 feet |

70 mph | 103 feet | 245 feet |

80mph | 117 feet | 320 feet |

## What is the stopping distance at 45 mph?

Stopping Distances

Speed | Thinking Distance 2 | Braking Distance |
---|---|---|

20 mph | 20 feet | 20 feet |

30 mph | 30 feet | 45 feet |

40 mph | 40 feet | 80 feet |

50 mph | 50 feet | 125 feet |

## What is the stopping distance at 70 mph?

Stopping distances at different speeds

Speed | Thinking + braking distance | Stopping distance |
---|---|---|

40mph | 12m + 24m | 36m (118 feet) |

50mph | 15m + 38m | 53m (174 feet) |

60mph | 18m + 55m | 73m (240 feet) |

70mph | 21m + 75m | 96m (315 feet) |

## What are the 3 parts of stopping distance?

Stopping distance consists of three factors: Driver’s reaction time + Brake lag + Braking distance.

## What 2 things make up stopping distance?

Your stopping distance is actually made up of two factors – thinking distance and braking distance.

## What three things are included in the total stopping distance?

The total stopping distance is the summation of the reaction distance, braking distance and perception distance. When you perceive a need to slow or stop the vehicle, a few seconds of time will pass.
