UNIT 4 PACKET Chapters 5, 6, and 12
Chapter 5:Natural Laws and Car Control GRAVITY Is the force that pulls all things to Earth. UPHILL DRIVING- Gravity will slow your car down when going uphill, unless you use extra power. DOWNHILL DRIVING- Gravity will increase your speed going downhill unless you control it. https://www.youtube.com/watch?v=5dZ8LOLn 0Pk https://www.youtube.com/watch?v=5dZ8LOLn 0Pk
TREAD and TRACTION Tread The grooved surface of a tire that grips the road. Allows water to flow through the grooves and away from the tire. This action allows the tire tread to cut through the water and grip the road.
TOTAL STOPPING DISTANCE TSD= The distance your car travels while you make a stop. T = P + RT + BD Total Stopping Dist = Perception + Reaction Time + Braking Dist. Perception: The length of time you take to identify, predict, and decide to slow. Reaction Time: The length of time it takes for you to execute your action. Braking Distance: The distance your car travels from the time you apply the brakes.
PACKET WORK: 1. In pairs, complete the chart on pg 1 of your packet. 2. Pg.2: Use the chart in your book on pg.98 and the information in your packet to describe TOTAL STOPPING DISTANCE in complete sentences!!
STEERING YOUR VEHCILE Steering Straight Forward: 1.Hands in a comfortable, balanced position at 9 & 3 2.Look ahead into your intended path of travel.
Steering Straight Backwards: Driving backward involves knowing where to look and how to control direction and speed. Before backing, make sure your rear zones are clear.
SIGNALING What’s the point?????? Answer in at least 2 complete sentences. When making a left or right hand turn in a business or residential district, a continuous signal to turn must be given….. No less than 100 feet before turning!!!!
If your turn signals or brake lights are not working, you must use proper hand signals to communicate your intentions to other roadway users. https://www.youtube.com/watch?v=d2nWvrxPewU
HAND OVER HAND STEERING Hands in Start pulling down Release the left balanced 9&3 with the left hand and cross it over & up and over with the right, and the right continue pulling down
Making Left and Right Turns
Steps or making a right turn Begin turning the wheel when your car’s front bumper is even with the curb line
Steps for making a left turn: Begin turning the wheel just before the front of the car reaches the center of the intersection.
Turning the Vehicle Turnabouts: Turning your car around to go in the opposite direction. All turnabouts are high-risk maneuvers! Take these precautions when making a turnabout: 1. Be sure local laws permit the turnabout. (check for signs) 2. Select a site with at least 500 feet of visibility in each direction. 3. Do not make a turnabout near hills or curves or within 200 feet of intersections. 4. Never attempt a turnabout in heavy, high-speed traffic. 5. Continually check all zones for traffic and pedestrians
Midblock U-Turn: Make sure state laws permit this type of turn. You need a wide space to make a U-Turn. This is risky because you have to cross lanes of traffic to execute it.
Steps for making a midblock U-turn on a 2-way road. 1.Check your front and rear zones, signal right, pull to the far right, and stop. 2.Signal left and move toward location # 2. 3.Check front and left-rear zones, check left blind spot, turn sharply left and move toward location #3. Don’t stop if you have enough space to complete the turn. 4.Move slowly to location #4, check all zones, and straighten out your wheels while you accelerate gently into the proper lane.
Three-Point Turns: Are high-risk because you cross traffic lanes AND are stopped across traffic lane. 1.Check front and rear zones. Signal right and stop close to the curb. 2.Search front and rear zones (including over your left shoulder). Signal left, turn wheel sharply to the left and move to location 3 before hitting the curb. Once there, straighten wheels.
Parking VOCABULARY Pg 119DEFINITION Reference Point Standard Reference Point Personal Reference Point Define the vocabulary below in your won words. These words can be found on page 119 in your book.
Angle Parking Steps to follow in completing Angle Parking: 1.Check for traffic and pedestrians Position vehicle at least 6 feet from the row of parked cars. Signal a right turn, check traffic to the rear, and begin braking. 2.Check your right blind spot and continue braking. 3.Creep forward until you can see the center of the space without your line of sight cutting across the parking line. Turn your wheel sharply to the right and slowly enter the parking spot. 4.Straighten the wheels when you are centered in the space. Make sure your front bumper is even with the curb or parking line.
Perpendicular Parking. Steps to follow when completing perpendicular parking: 1.Position your vehicle at least 8 feet from the row of parked vehicles, or as far left of the lane as possible and begin to brake. 2.Signal a right turn, check your right blind spot, and begin to brake. 3.Check traffic to the rear, and continue braking. 4.When your front bumper passes the left rear taillight of the vehicle to the right of the empty parking space turn your wheel sharply to the right. Check your right-rear fender for clearance. 5.Straighten your wheel when you are centered in the space.
Parallel Parking Use parallel parking to park your vehicle parallel to the curb. Select a space that is 5-6 feet longer than your vehicle.
During your maneuver, the front of your vehicle will swing far to the left. Check over your left shoulder to be sure this needed space is clear.
Steps to Follow When Leaving a Parallel Parking Space: 1.Back straight slowly until your rear bumper almost touches the vehicle behind. Turn wheel sharply to the left. 2.Signal left turn. Check your left blind spot. 3.Check the right-front corner of your vehicle for clearance. 4.Turn your wheels to the right when you are halfway out of the parking space. Scan zones and then proceed into traffic lanes.
PARKING Uphill Parking with a Curb 1. Position your vehicle close to the curb. Just before stopping, turn the steering wheel to the left. 2. Shift to neutral; let the vehicle creep back until the back of the right-front tires gently touches the curb. 3. Shift to park, and set the parking brake. 4. When leaving the parking space signal, check traffic, and accelerate into the lane of traffic. https://www.youtube.com/watch?v=VXwt_j9JrQw https://www.youtube.com/watch?v=VXwt_j9JrQw
PARKING Uphill Parking With No Curb 1.Pull as far off the roadway as possible. Turn the wheel to the right. 2.Shift to park, and set the parking brake. 3.When leaving the parking space, let the vehicle creep backward while straightening the wheels. Signal and check traffic. Shift to drive, and accelerate into traffic.
Ch 12. Driving in Adverse Conditions
Visibility While Driving SUN GLARE Can create severe and blinding conditions. The brightest day will create the darkest shadow, with severe glare situations behind you, so be prepared for other drivers to miss seeing your signal or even seeing your vehicle. Sun glasses and a sun visor can help. Driving with low-beam head lights on all the time will help other drivers see you
Visibility While Driving
Snow and Ice
Can you think of other road types that might interfere with traction while driving? Gravel Roads Leaves Construction areas
Skidding In extreme traction situations, your tires may lose all or part of their grip on the road.
Skidding Front-Wheel Skid When your steering wheel and your vehicle wants to slide straight ahead. To correct this you need to regain traction for steering. You do this by: 1.Releasing the accelerator or brake pedal pressure 2.Quickly apply and release the brake pedal to slow if your vehicle does not have ABS 3.Continue to look and steer at the path of travel you want to follow.
OTHER ADVERSE WEATHER CONDISTIONS HOT WEATHER Your temperature light gauge indicates when your engine is too hot. When this happens, turn off your air conditioner. You can also cool your engine by turning on your heater. REAR WHEEL SKID: If the rear end of your vehicle starts to skid, you should turn your wheels in the direction of the skid.
COLD WEATHER Carbon monoxide gas is created when your engine runs sooooooooooo……. If you are stuck in the snow with your engine running, make sure your exhaust pipe is not blocked. Ice or slush to the underside of your vehicle can freeze your parking brake when you park your vehicle
