Factors affecting braking distance
Factors affecting braking distance
Speed, road/weather, tyre condition, brake condition
Vehicle speed effect on braking distance
Vehicle speed effect on braking distance
Faster = longer braking distance
Wet/icy roads effect on braking distance
Wet/icy roads effect on braking distance
Increases braking distance
Why wet/icy roads increase braking distance
Why wet/icy roads increase braking distance
Decrease friction, cause skidding
Worn tyres effect on braking distance
Worn tyres effect on braking distance
Increases braking distance
Why worn tyres increase braking distance
Why worn tyres increase braking distance
Reduced tread → less friction → more skidding
Worn brakes effect on braking distance
Worn brakes effect on braking distance
Increases braking distance
Why worn brakes increase braking distance
Why worn brakes increase braking distance
Less friction between brakes & wheels → less braking force
