Thinking Distance and Measuring Reaction Times

• What is the thinking distance in driving?

  How far the vehicle travels during reaction time
• Why do reaction times vary among individuals?

  They differ from person to person
• What is the typical range of reaction times?

  0.2 s to 0.9 s
• What factors can affect a driver's reaction time?

  Tiredness, drugs, and alcohol
• How can distractions impact a driver's ability to react?

  They may affect the driver's reaction ability
• What are typical methods for measuring reaction times?

  • Drop tests where a person catches a falling ruler
  • Driving simulations
  • Computerized tests
