  1. Objectives: • Students will understand what causes glare • Students will understand how to avoid glare • Students will understand visibility limitations at night • Students will understand headlight alignment and speed considerations • Students will understand nighttime driving precautionary measures

  2. Bell Ringer #2 • Write a half a page redtored. Save these to be turn in on test day. Worth 10% of your grade. • When students move to a new school, they sometimes face problems. How can schools help these students with their problems? Use specific reasons and examples to explain your answer.

  3. Reminder Bring paper/pen/pencil and notebook Electronics are for instructional use with permission Don’t forget to do daily quizzes on QUIA.COM No Excuses why you don’t take Quizzes 1-6 before test day!! (Quizzes are worth 30% of grade) Attendance is MANDATORY!! (NO SLEEPING in class) All notes can be found on Harrisonburg’s staff website: http://staff.harrisonburg.k12.va.us/~tbutler/ If you are NOT taking notes in class, please be quiet and ask to use the restroom at the end of class.

  4. Section 5 Day 2 Driver Responsibility: Adverse Conditions

  5. Glare When the sun’s rays, street/sign lights or headlights of another vehicle shine directly into your windshield.

  6. Snow-covered landscape Facing the sun at dawn or dusk Flashing advertisement Flood lights on side of streets Traditional vs. Contemporary mirror settings Sources of Glare

  7. Oncoming and following vehicle headlights High beam Misaligned headlights Vehicle loaded improperly Dirty windshield Paper on dashboard Sources of Glare

  8. Avoiding Glare • Keep windshield clean

  9. Reduce speed and look down to the right-hand side of the road; make brief glances ahead to monitor path of travel Avoiding Glare

  10. Avoiding Glare • To avoid being blinded by headlights of following vehicles, use BGE side mirror settings; • Adjust your side mirror to “night” setting

  11. Never wear sunglasses at night Avoiding Glare

  12. Visibility Limitations at Night The ability to identify risks depends on vision, and visual acuity is severely limited at night.

  13. Headlight Alignment and Speed The Code of Virginia requires that you use your headlights from sunset to sunrise and during bad weather, such as rain, fog, snow, or when you use your windshield wipers. • The posted speed limits are calculated for daylight driving and are often too fast for nighttime conditions. • Dirty headlights and improper headlight alignment will add to this traffic safety problem.

  14. Headlight Alignment and Speed Properly aligned LOW BEAM headlights • beam hits roadway 100 to 150 feet ahead • Illuminates (light up) area above road 300 to 500 feet ahead • load, load distribution, and vehicle height affect light beam distance • a maximum safe speed of 40 to 45 mph is based on your ability to stop within the lighted area illuminated roadway 100 to 150 feet lighted area above road 300 to 500 feet

  15. Headlight Alignment and Speed • the beam hits the roadway 300 to 500 feet ahead • illuminates the area above the road 500 to 1800 feet ahead • load, load distribution, and vehicle height affect light beam distance • maximum safe speed is 65 mph based on your ability to stop within the lighted area Properly Aligned High Beam Headlights illuminated roadway 300 to 500 feet lighted area above road 500 to 1800 feet

  16. Headlight Alignment and Speed Lower (dim) high-beams headlights when you are: • within 500 feet of an approaching vehicle • following closely behind another vehicle (within 200 feet) • driving on lighted roadways • driving in fog, heavy rain, sleet, snow, or dust

  17. Nighttime Precautionary Measures • Clean windshield inside and out. • 50 to 90 percent loss of headlight efficiency is due to road grime.

  18. Nighttime Precautionary Measures • Reduce speed. • Increase following interval. • Turn off interior lights. • Look to the right of oncoming vehicles. • Use high/low headlight beams properly. • Use parking lights only when parked. If stopped beside road, take appropriate safety measures. • Use day/night switch on rearview mirror.

  19. Nighttime Precautionary Measures Pedestrian safety • Be alert for pedestrians walking on unlighted roadways after dark. • If you must walk on a dark roadway due to vehicle breakdown or for any other reason, carry a white handkerchief or wear light-colored clothing. If possible, wear reflective vests or other reflective clothing if you must be on or near a road at night. Don’t Wear Dark Clothes Carry a Handkerchief Retro-reflective Material Wear Stripes

  20. Class Work In your driver’s education book, read pages 220-221. Do Lesson review questions (1+2) on page 221. Save these to be turned in with your test! Don’t forget to take Section 5 Day 2 Quiz on Quia.com

  21. THE END!
