STOPPING DISTANCES
REACTION TIME = time for a driver to react
Meanwhile the car covers a “ THINKING DISTANCE”
OVERALL STOPPING DISTANCE
= THINKING DISTANCE +
BRAKINGDISTANCE
The overall stopping distance increases when:the thinking distance increases:
* the driver has a slower reaction time, { eg from drugs, tiredness, alcohol, poor visibility}
Also the overall stopping distance increases when:the braking distance increases:
i) there is rain, ice, fog stones,
ii) Poor brakes or tyres.
iii) the car’s speed & mass increase,
Then the car needs;a bigger braking force ora longer distance to stop
