  • Stopping Distances
    • Factors that affect it
      • Speed
        • Faster = bigger braking force
          • = bigger stopping distance
      • Thinking Distance
        • SPEED
          • Faster = further travelled
        • Bad visibility
          • Doesn't affect thinking distance, but you START thinking a lot NEARER to the hazard
            • Distractions
              • e.g. radio, bright oncoming lights
          • e.g. torrential rain
        • Distractions
          • e.g. radio, bright oncoming lights
        • Concentration
          • e.g. tiredness, drugs, alcohol & carelessness
      • Braking Distance
        • SPEED
          • Faster = further travelled
        • Quality of Brakes
          • MUST be checked regularly
        • Quality of Tyres
          • Should have minimum TREAD DEPTH of 1.6mm
            • To get rid of water in wet conditions
        • Amount of Grip
          • Tyres
            • Quality of Tyres
              • Should have minimum TREAD DEPTH of 1.6mm
                • To get rid of water in wet conditions
          • Road surface
          • Weather conditions
            • e.g. wet or icy = much more slippy
    • Total stopping distance is distance covered in time between driver 1st spotting hazard & car stopping completely
      • = sum of thinking & braking distance
