5. Objectives: (Day 4) Students will understand safety restraints for adults Students will understand types of belt-locking systems Students will understand roadway technology Students will understand vehicle technology Students will understand controlling consequences

6. Occupant Protection Refers to safety belts, child restraints, and driver/passenger side air bags. Video

7. Seat Belts Your number one defense to prevent severe injuries is to wear your safety belt.

8. Keeping the seat back in an upright position avoids the submarine effect of the lower body in a frontal crash Keeping the seat back in an upright position avoids the submarine effect of the lower body in a frontal crash Minimize movement of the upper and lower body in a crash Minimize movement of the upper and lower body in a crash Dramatically reduce the severity of injuries Dramatically reduce the severity of injuries Seat Belts Seatbelt Video

9. Normal Conditions Emergency Conditions Seat Belt Ratchet Mechanism Pendulum Bar Sudden Car Movement Types of Belt-Locking Systems

10. Head Restraints Proper adjustment minimizes whiplash. Improper adjustment may result in severe neck injury. Adjust to a position above the ear level to avoid serious injury

11. Air Bags in Dash or Steering Wheel No passenger under 12 years of age should sit in the front seat No passenger under 12 years of age should sit in the front seat Protect driver or passengers from sustaining severe head and chest injuries Protect driver or passengers from sustaining severe head and chest injuries The air bag inflates in the blink of an eye, at speeds as high as 200 miles per hour.

12. Air Bags in Dash or Steering Wheel Raise seat or adjust steering wheel to direct air bag toward chest and not at the facial areaRaise seat or adjust steering wheel to direct air bag toward chest and not at the facial area Adjust seat for a minimum 10-inch clearance between chest and steering wheelAdjust seat for a minimum 10-inch clearance between chest and steering wheel Hand position should be at 8 and 4Hand position should be at 8 and 4 Avoid 10 and 2 hand position to prevent blow hole burns to hands and armsAvoid 10 and 2 hand position to prevent blow hole burns to hands and arms 10 inches

13. Air Bags for side impact protection Located in the upper door frame, side of the seat, or door panel Protect head from hitting the window Side air bag deploys in crash test. Red area shows where the dummy’s head impacted the airbag. Side Airbag Video

14. Safety Restraints for Youth Belt and Seat Restraint Use T – 8.24  Safest if seated in back center seat  Infant seats/rear facing/birth to 20 lbs.  Use child seats up to 40 lbs.  Use booster seats up to 60 lbs. Infant Car Bed Rear Facing Infant Seat Forward Facing Child Restraints Booster Seats

15. Roadway and Vehicle Technology

16. Roadway Technology Wide clear shoulders and wide lanes Rumble strips installed at the road edge Redesign of median barriers Occupant Protection Highway Design Features Include Occupant Protection Highway Design Features Include

17.  Breakaway sign support posts Occupant Protection Highway Design Features Include Roadway Technology  Vinyl Crash drums filled with liquid or sand  New design guard rails with ends angled away from roadway and buried

18. Roadway Technology Variable message signs alert drivers to weather conditions, construction, and traffic problems

19. Automotive Technology New vehicle technology aids the driver in maintaining balance control when performing avoidance maneuvers and increased protection should a crash occur. Enhanced control is provided through technologies such as the following: Anti-Lock Brakes Crumple Zones Crumple Zones Traction Control Devices Traction Control Devices Electronic Stability Program (ESP) Electronic Stability Program (ESP) Suspension Control Devices Suspension Control Devices Door Latches Door Latches Tempered Glass Tempered Glass DON’T WRITE THIS SLIDE

20. Brake Systems

21. Anti-lock Brake Systems Designed to allow steering and simultaneous braking without losing vehicle balance. Shorten stopping distances by not allowing the tire to lock up ABS VIDEOVIDEO

22. Anti-lock Brake Systems Do..  Add to your following distance in bad weather  Practice use of ABS  Keep your foot firmly on the brake INCREASE INCREASE

23. Anti-lock Brake Systems Do Not..  Drive More Aggressively  Pump the Brakes  Steer Too Much  Be Alarmed by ABS Noise or Vibration

24. Traction Control Systems Basically the reverse of anti- lock brakes. Designed to activate brake sensors, which do not allow the wheels to spin. The device allows acceleration input without loss of vehicle balance.

25. Crumple Zones Areas of a vehicle that are designed to deform and crumple in a collision. This absorbs some of the energy of the impact, preventing it from being transmitted to the occupants. Crumple Zone Video Crumple Zone Video

26. Crashes have two separate collisions: The first is the vehicle collision, and the second is the collision of occupants and unsecured items inside the vehicle. It is this second collision that often causes injury and death.

27. Honda Civic Crash

33. Controlling Consequences Drive off road rather than skid off the road Hit something soft rather than something hard Hit something going your way rather than something stationary Hit stationary objects with a glancing blow Hit a stationary object rather than an approaching object Steer to avoid oncoming traffic and head on collision

34. Class Work In your driver’s education book, read pages 118-122. WRITE Lesson review 2 questions (1-3) on page 122. Save these to be turned in with your test! Don’t forget to take Section 5 Day 4 Quiz on Quia.com
