STOPPING DISTANCES

It's

Stopping distances

Try this "simple" formula

• x2 ÷ 20 + x = Overall stopping distance in feet where x = speed
• Whilst you hunt for the calculator you'll probably hit the vehicle in front

Thinking Distance?

• This is the distance you travel thinking about braking

Braking Distance?

• This is how far you carry on going whilst pushing on the brake pedal

Total Stopping Distance?

• This is how far you went before you finally stopped
• It's your thinking distance and stopping distance added together

• But not everyone drives modern "high tech" vehicles
• Picture the driver with a highly modified 10 year old vehicle
• Fitted with a state of the art music system
• And a state of the art lighting system: often underneath the car
• With a braking system that uses 10 year old technology
• Driven by someone with 10 months driving experience

It's why "stopping distances" haven't attempted to keep up with technology

• Stopping distances are based upon a normal mass produced family car
• Stopping distances are based upon an alert driver on a dry road with good brakes and tyres
