What are the three factors of stopping distance?
Stopping distance consists of three factors: Driver’s reaction time + Brake lag + Braking distance.
What is a safe distance to travel behind another car?
three seconds
What factors affect stopping distance of a vehicle?
10 things that can affect your stopping distance
- Speed. Your stopping distance is actually made up of two factors – thinking distance and braking distance.
- Brakes.
- Tyre Pressure.
- Tyre Wear.
- Tyre Quality.
- Road Conditions.
- View of the Road.
- Distractions.
What is the braking distance of a vehicle?
Stopping distances at different speeds
| Speed | Thinking + braking distance | Stopping distance |
|---|---|---|
| 20mph | 6m + 6m | 12m (40 feet) |
| 30mph | 9m + 14m | 23m (75 feet) |
| 40mph | 12m + 24m | 36m (118 feet) |
| 50mph | 15m + 38m | 53m (174 feet) |
How many car lengths stop at 70 mph?
Driver Care – Know Your Stopping Distance
| Speed | Perception/Reaction Distance | Equal to Approx Number of Car Lengths (@15 feet) |
|---|---|---|
| 40 mph | 59 feet | 9 |
| 50 mph | 73 feet | 14 |
| 60 mph | 88 feet | 18 |
| 70 mph | 103 feet | 23 |
When should you start braking?
Brake early When approaching a red light or stopped vehicle start braking at about 200 feet back (about the length of long turn lane on a major highway), a little more than that at speeds 40 MPH or more. That far back you can be using less pressure on the brake and still stop with plenty of space in front of you.
Is it better to brake quickly or slowly?
Slow and gradual is better unless you’re on a racetrack or need to panic stop. Heat dissipates more easily when you’re making a little friction over a long time, and your brake pads and rotors will last way longer. Don’t worry about the 1000 times you will coast to save breaks pads.
