  3. What are driver contributed factors? • Adjusting music • Anger • Blurred vision • Grooming • Drinking while driving • Cell phone

  4. Vehicle contributed factors • Bald tires • Brake problems • Dirty windshield • Broken headlight • Worn windshield wipers

  5. Roadway/Environmental Factors • Bright sun • Construction • Shadows • Snow & ice • Sharp curves

  6. What things should you "Identify" • Signs • Car turning • Pedestrian • Red light • Road conditions

  7. What is an "Open Zone"? • There is no restricted view • What is a "Closed Zone"? • The view is restricted as in a Red light

  8. What things can you "Predict"? • Actions of other people • Speed - yours & others • Direction • Control • Points of conflict

  9. What things can you "Decide"? • To change speed • To change direction • Communicate

  10. What things can you "Execute"? • Controlling your speed • Steering • Communicate • Combine any actions

  11. Smith System • Aim high while steering - 12-15 seconds ahead • Get the big picture - put clues together • Leave yourself an "out" • Make sure they see you

  12. Zone Control System • See a zone change- LF, LB, F, R, RF, RB (width of a lane and extends as far as you can see) • Check other zones • Create time & space by getting the best speed control, lane position & communication

  13. IDENTIFY & PREDICT

  14. What is the "Target Area Range""? • Space from vehicle to target area • 12-15 second range • Space with the next 12-15 seconds of travel • Locked brakes make what impossible? • Steering

  15. What is the "Orderly Visual Search Pattern"? • Looking and evaluating from target area throughout all zones and checking all ranges • Checking mirrors • Should only glance for a second/don't stare

  16. What is "Field of Vision"? • Area you can see while looking straight ahead- includes peripheral vision • How many searching ranges are there? • 3 - target area/12-15 second range/4-6 second range

  17. What are some roadway features and conditions to look for? • Intersections • Curves • Hills • Lane changes • Change of lane width • Roadway surface - weather • Roadside hazards • Eg. Bikes/pedestrians/parked vehicles/animals

  18. DECIDE & EXECUTE

  19. In what ways can you change your speed? • Decelerate/Brake/Accelerate • What ways can you change direction? • Move towards the right or left side of the lane/change lane/ leave a space cushion

  20. Lane Positions • Lane 1: center of lane • Lane 2: left side of lane • Lane 3: right side of lane
