Driver Education Section VI Day 1 - Occupant Protection

SOL DE 14 The student will demonstrate an understanding of the proper use of vehicle occupant protection features and analyze how they reduce injury severity and increase collision survival a. Active restraint system b. Passive restraint system c. Child restraint system d. Highway safety design

Objective The student will –Understand the proper use of seatbelts, airbags, and child restraints

Day 1 – Occupant Protection Bell Ringer – #1 –3 paragraphs 5 sentences each –Describe your experience riding in a car during braking and accelerating. What does it feel like to be a passenger in a car that suddenly stops? Suddenly accelerates? Why do you think wearing safety belts is especially important in these situations? Why is it important for all passengers in the car to buckle up? What are some other features on a car that make it safer?

Safety Belts DMVM > 20 Text Book > 120 Can double your chances of surviving a crash and more than double your chances of avoiding serious injury. Reduces chances of being killed by 50% and reduces chance of serious injury by 70%.

Buckle up to guard against additional injury from a secondary collision or ejection from the vehicle Accidents have three separate collisions: 1. The vehicle collision, the car hits something. 2. The occupant collision, the occupant hits unsecured items inside the vehicle. 3. The organs of the body colliding with the skeletal system. COPY THIS SECTION

Virginia Safety Belt Laws DMVM > 20 Requires drivers and front seat passengers to use safety belts. A driver transporting anyone through age 15 must make sure that the child is properly secured in a safety belt, booster seat or child safety seat no matter where the child is seated.

Virginia Law for Children DMVM > 21 DOE PP > Module 8 All children under age eight must be properly secured in a child safety seat or booster seat. 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.

Air Bags DMVM > Text > 120 They cushion occupants as they move forward in a front-end crash. The air bag keeps the occupant’s head, neck and chest from hitting the steering column or dashboard. Some vehicle’s have air bags that inflate in a side collision. Air bags do not take away the need to wear safety belts.

Vehicle Systems — Brake Systems How Brakes Work Brakes are actually energy conversion devices. kinetic energy thermal energy When you step on the brakes, they convert the kinetic energy (momentum) of your vehicle into thermal energy (heat). Thousands of pounds of pressure are applied on each of the four brakes, permitting the driver to slow or stop the rotation of the tires. The friction of the tires against the road surface will then slow and/or stop the vehicle. DO NOT WRITE THIS SLIDE DOE PP> Module 9

Anti-Lock Braking System (ABS) Topic 2 Lesson 1 * ABS was developed to assist driver braking actions by preventing tires from sliding and to keep them rotating slowly to allow steering. Vehicle Systems — ABS Brake System DOE PP> Module 9 Handout

Enhanced Braking Action Reduced Stopping Distance Increased Vehicle Stability Enhanced Vehicle Steerability ABS Advantages Braking and Steering In many emergency situations braking alone may not prevent a collision. Handout DOE PP> Module 9

1.Increase your following distance in bad weather 2.Practice using ABS 3.Keep your foot firmly on the brake even if it vibrates 4.Check owner’s manual for special concerns With ABS… INCREASE INCREASE DOE PP> Module 9 Handout

1.Drive More Aggressively 2.Pump the Brakes With ABS, Do Not 3. Steer Too Much 4. Be Alarmed by ABS Noise or Vibration DOE PP> module 9 Handout

Highway Design Features DOE PP> Module 8 1-Breakaway sign support posts 3- Crash attenuators such as vinyl liquid or sand filled drums 2- New design guard rails with ends angled away from roadway and buried Handout

Highway Design Features DOE PP> Module 8 4-Protected left and right turn bays 5-Collector/distributor lanes on high speed, high density highways - separates slower moving entering/exiting traffic from the higher speed through traffic 6-Variable message signs alert drivers to weather conditions, construction, and traffic problems Handout

Class Work #2 3 paragraphs, 5 sentences each Come up with TWO additional safety features, for either the car or the roadway and explain why your safety features should be used and how they are to be implemented. Work on until the end of the class
