🧠 Factors Affecting THINKING Distance

Thinking distance = speed × reaction time

Factors that INCREASE reaction time:

  • Tiredness — slower brain processing
  • Alcohol — impairs judgment and reactions
  • Drugs (legal and illegal) — various effects on brain
  • Distractions — phone, passengers, eating
  • Age — older drivers typically react slower
  • Poor visibility — takes longer to recognise hazard

Factors that INCREASE thinking distance:

  • Higher speed — travel further during same reaction time
  • All the factors above (via increased reaction time)

Practice Questions for Stopping Distances

What is the correct definition of stopping distance?

  • A. The distance the car travels while the brakes are applied only
  • B. The distance the car travels during the driver's reaction time only
  • C. Thinking distance plus braking distance
  • D. The speed of the car divided by the braking force

Explain why a car travelling at higher speed has a greater braking distance than a car travelling at lower speed, assuming the same braking force.
