## What is the relationship between stopping braking and thinking distance?

Stopping distances thinking distance is the distance a vehicle travels in the time it takes for the driver to apply the brakes after realising they need to stop. braking distance is the distance a vehicle travels in the time after the driver has applied the brake.

### How much braking distance does it take to stop at 60 mph?

Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances.

#### How do you calculate braking and thinking distance?

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 factors increase braking distance?**

The braking distance of a vehicle can be affected by:

- poor road and weather conditions, such as wet or icy roads.
- poor vehicle conditions, such as worn brakes or worn tyres.
- a greater speed.
- the car’s mass – more mass means a greater braking distance.

**What is the braking distance at 60 mph?**

Check out the total stopping distance equations below for vehicles driving at various speeds. 60 mph: Thinking Distance of 60 feet + Braking Distance of 180 feet = Total Distance of 240 feet 40 mph: Thinking Distance of 40 feet + Braking Distance of 80 feet = Total Distance of 120 feet

## How does thinking distance affect the braking distance?

The thinking distance depends on the reaction time of the driver which could be affected by drugs, alcohol, distractions and tiredness. This distance will also be affected by the car’s speed. The braking distance also depends on the speed of the car, the mass of the car, how worn the brakes and tyres are, and the road surface.

### How long does it take to think about stopping distance?

It’ll take you time (and distance) to react to what’s happening, decide to brake, and then hit the pedal. The Highway Code bases its thinking distances on a thinking time of just under 0.7 seconds. The faster you’re going, the further you’ll travel in that time. The thinking distance at 50mph is 15m, nearly the length of 2 London buses.

#### How does the speed of a car affect the stopping distance?

A faster speed increases both thinking and braking distance, increasing the total stopping distance. You might be asked to look for patterns in car stopping distances, and how they change with the speed of a car. Look at the diagram and answer the question. A car doubles its speed from 30 mph to 60 mph. How does this affect:
