Stopping distance

Total distance from seeing hazard to vehicle stopping

Thinking distance

Distance between seeing hazard & applying brakes

Braking distance

Distance from applying brakes to stopping

Stopping distance formula

Stopping Distance=Thinking Distance+Braking Distance\text{Stopping Distance} = \text{Thinking Distance} + \text{Braking Distance}

What thinking distance depends on

Driver's reaction time

What braking distance depends on

Braking force

Effect of greater speed (given braking force)

Greater stopping distance

Factors affecting stopping distance

Braking force and reaction time

If stopping distance is higher, you should

Leave more space between vehicles

When does stopping distance start?

When driver sees the hazard
