Stopping Distance: Is The Highway Code Wrong?
| Speed | Stopping Distance |
|---|---|
| 40mph | 36 Meters / 118 Feet |
| 50mph | 53 Meters / 175 Feet |
| 60mph | 73 Meters / 240 Feet |
| 70mph | 96 Meters / 315 Feet |
How do you remember stopping distances?
The factors are easy to remember – just start at 2 for 20mph and add 0.5 for each 10 mph increase in speed. Example: Question: What is the overall stopping distance at 50mph? Answer: Factor for 50mph is 3.5 and so overall stopping distance at 50mph is 50 x 3.5 = 175 feet.
Do you need to Memorise stopping distances?
Probably more important than learning the quoted stopping distances is knowing just how much further it takes to stop at higher speeds, I.E at 30 mph the quoted stopping distance is 75 feet but add an extra 10 mph and at 40 mph the quoted stopping distance increases by 45 feet, that is more than a 50% increase.
How long does it take a car to stop 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) |
How many car lengths stop at 70 mph?
24 car lengths
40 mph x 3 = 120 feet (36.5 metres or 9 car lengths) 50 mph x 3.5 = 175 feet (53 metres or 13 car lengths) 60 mph x 4 = 240 feet (73 metres or 18 car lengths) 70 mph x 4.5 = 315 feet (96 metres or 24 car lengths)
What is the overall stopping distance?
Stopping Distance is the total distance you travel before you hit the brakes plus the distance you travel while the brakes slow you down. Thinking + Braking Distance = Overall Stopping Distance.
What is the shortest overall stopping distance at 60mph?
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 minimum stopping distance?
Explantion: The total minimum stopping distance of a vehicle depends on four things; perception time, reaction time, the vehicles reaction time and the vehicle braking capability. The recommend minimum stopping distance of a car driving at 100 km/h under dry conditions is 70 metres.
What is the stopping distance of a vehicle?
Stopping distance is the total distance you travel before you apply the brakes, plus the distance you travel while the brakes slow you down.
How do you calculate stopping distance in mph?
The braking distance, in feet, of a car traveling at v miles per hour is given by d= 2.2v+\frac{v^2}{20}.
How much distance should you keep between cars?
three-second
The rule of thumb is to maintain at least a three-second following distance, giving you time to react and avoid potentially dangerous situations. You can calculate this by using a fixed object, such as a pole or an overpass to determine how far in front of you the car is.
What is the 2 second following distance rule?
The 2-second rule is a technique used to estimate a safe following distance between your vehicle and the traffic ahead. It is a general rule of thumb taught in every driving school across the United States. The premise is that by following behind traffic by two seconds, you will have the time and space to brake safely.
How many car lengths is 60 mph?
Driver Care – Know Your Stopping Distance
| Speed | Perception/Reaction Distance | Equal to Approx Number of Car Lengths (@15 feet) |
|---|---|---|
| 50 mph | 73 feet | 14 |
| 60 mph | 88 feet | 18 |
| 70 mph | 103 feet | 23 |
| 80mph | 117 feet | 29 |
What are the highway code stopping distances?
The stopping distance at 20mph is around 3 car lengths….Stopping distances at different speeds.
| Speed | Thinking + braking distance | Stopping distance |
|---|---|---|
| 40mph | 12m + 24m | 36m (118 feet) |
| 50mph | 15m + 38m | 53m (174 feet) |

| 70mph | 21m + 75m | 96m (315 feet) |
How many feet does it take to stop at 70 mph?
Driver Care – Know Your Stopping Distance
| Speed | Perception/Reaction Distance | Overal Stopping Distance |
|---|---|---|
| 50 mph | 73 feet | 198 feet |
| 60 mph | 88 feet | 268 feet |
| 70 mph | 103 feet | 348 feet |
| 80mph | 117 feet | 439 feet |
How do you calculate stopping distance at 60 mph?
60 MPH = 88 fps. (fps=1.467 * MPH). If the vehicle deceleration rate is 20 fpsps (rather than the previously calculated 15 fps), then stopping time = 88/20 = 4.4 seconds.
