  3. Managing Time and Space Around Your Vehicle Perception/Reaction/Response Time Perception Time Time it takes to identify hazards Average perception time is ¾ second • Reaction Time • Time it takes to respond with accelerator, brake, or steering control • Average reaction time is ¾ second • Response Time • Total time it takes to complete the action

  4. Managing Time and Space Around Your Vehicle • What are some factors that can affect response time?

  5. Managing Time and Space Around Your Vehicle Factors Affecting Response Time • Medications • Alcohol • Illness • Age • Talking on Cell Phone • Others …. • Distractions • Inattention • Poor Visibility • Line of Sight Restrictions • Fatigue

  6. Lets test our response time!

  7. Total Stopping Distance- the distance your car travels when you make a stop • Depends on: • Perception time • Perception distance • Reaction time • Reaction distance

  8. Managing Time and Space Around Your Vehicle FOLLOWING DISTANCE • Drivers have the most control over the space directly in front of the vehicle

  9. Managing Time and Space Around Your Vehicle ESTABLISH FOLLOWING DISTANCE one-thousand-one one-thousand-two one-thousand-three one-thousand-four

  10. Managing Time and Space Around Your Vehicle

  11. Good Habits for Following Distance • Increase Following Distance When: • Visibility is limited • Traction is limited • Increased visual and mental tasks are needed • Being tailgated • Carrying a heavy load or pulling a trailer • Learning to drive

  12. Managing Time and Space Around Your Vehicle • 2-Second Following Distance • Insufficient for today’s traffic environment • 3-Second Following Distance • May be enough time to steer away from a problem on dry surfaces or brake at speeds up to 45 mph • 4-Second Following Distance • Provides time to steer out of a problem on dry surfaces and brake out of a problem at speeds up to 70 mph

  13. When stopping at a red light, how far back should you be from the car in front of you? . . . . .

  14. Far enough back so you can still see some of the__________ tires

  15. Managing Time and Space Around Your Vehicle When the light turns green, why delay moving into the intersections for two seconds?

  16. Managing Time and Space Around Your Vehicle • THREE WAYS TO MANAGE SPACE TO THE FRONT • Adjust speed • Adjust lane position • Communicate

  18. LANE POSITION 1 In the center of the lane. Allows 3 feet on each side. 1 • LANE POSITION 2 • 3-6 inches from a line to the left. • Used for left turns, parking on the left, and to increase your line of sight. 2 • LANE POSITION 3 • 3-6 inches from a line to the right. • Used for parking, and to increase your line of sight. 3 LANE POSITIONS

  19. What should your lane position be in this situation?

  20. What should your lane position be in this situation?

  21. What should your lane position be in this situation?

  22. Managing Time and Space Around Your Vehicle Control Space to the Rear • Check rearview mirrors often (8-10 sec) • When being tailgated, increase your following distance • Communicate • Control speed • Change lanes or lane position

  23. REDUCED RISK DECISION-MAKING Three Precision Actions Available to Drivers • Communicate • Change Speed • Change Lanes or lane position
