6STEERING YOUR VEHCILE Steering Straight Forward: Hands in a comfortable, balanced position at 9 & 3Look ahead into your intended path of travel.
7Hold the brake pedal down and shift to REVERSE. 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.Hold the brake pedal down and shift to REVERSE.Turn your body to the right, and put your right arm over the back of the passenger seat, Look back through the rear window.Put your left hand at the top of the steering wheel at the 12 o’clock position.Release pressure on the brake just enough to allow the vehicle to creep backward slowly.While looking back through the rear window, move top of the steering wheel in the direction you want the back of the vehicle to go.Keep your foot over the brake pedal while your vehicle is moving backward. Glance quickly to the front and sides to check traffic. Continue to look back through the rear window as you brake and stop. Quick backing video

9If 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
10HAND 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 downTo straighten the wheel you can either relax your grip on the wheel to let it slide through your hands or unwind using the hand over hand process.hand position and hand over hand
11Making Left and Right Turns Making Turns: Requires steering control, speed control and good visual habits.Make sure to make a left or right turn only after checking all traffic. Take these precautions when executing turns:Look for pedestrians and oncoming vehicles, Check rear zones for vehicles about to pass you.
12Plan turns well in advance Plan turns well in advance. Be in the correct lane about one block before your turn.Obey all traffic signs, singles, and roadway markings. Remember you must yield to oncoming traffic when you are turning left.left and right hand turns
14Steps or making a right turn Begin turning the wheel when your car’s front bumper is even with the curb line
15Steps for making a left turn: Begin turning the wheel just before the front of the car reaches the center of the intersection.
16Turning the VehicleTurnabouts: 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
17Midblock 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.
18Steps for making a midblock U-turn on a 2-way road. Check your front and rear zones, signal right, pull to the far right, and stop.Signal left and move toward location # 2.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.Move slowly to location #4, check all zones, and straighten out your wheels while you accelerate gently into the proper lane.
19Check front and rear zones. Signal right and stop close to the curb. Three-Point Turns: Are high-risk because you cross traffic lanes AND are stopped across traffic lane.Check front and rear zones. Signal right and stop close to the curb.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.
203. Check all zones for traffic, turn wheels sharply right while backing slowly to location 4. Back only as far as necessary tom complete the maneuver and before hitting the curb.

33Ch 12. Driving in Adverse Conditions Reduced VisibilityWhenever visibility is reduced drivers need more time to use the IPDE Process. You can maintain a safe intend path or travel by……..Slowing down to give yourself more time.Scanning in and around your path of travel to the target area to identify hazardsPredicting others will make maneuvers into your intended path of travel.Deciding where to position your vehicle ahead of time with extra space around it.Ch 12. Driving in Adverse Conditions
34Visibility While Driving Can create severe and blinding conditions.Sun glasses and a sun visor can help.SUN GLAREThe brightest daywill create thedarkest shadow,with severe glaresituations behind you, so be prepared for other drivers to miss seeing your signal or even seeing your vehicle.Driving with low-beam head lights on all the time will help other drivers see you
35Visibility While Driving HEADLIGHTSUse high beam headlights to look beyond your headlights for important information.Only use high beam headlights when vehicles are more than one-half mile in front of you.Use low-beam headlights in snow, heavy rain, or fog.Using high-beam headlights will reflect more light back into your eyes, as a result, you will see less.Make sure to use your low-beam headlights when you are driving in the rain. (Most states require your low-bema headlights to be when on using your wipers).During snow use your low-beam headlights day or night.High beam vs low beam videoVisibility While Driving
36Reduced TractionRAIN WHILE DRIVING:When rain first begins to fall, it mixes with dust and oil on the road. This mix can make the road very slippery.HYDROPLANING: When a tire rises up on top of the water and no longer has contact with the road. (you car is water skiing!! YIKES)crazy hydroplaning crashesShore-Drive html
37Use properly inflated tires with good tread. How to Avoid HydroplaningReduce speedUse properly inflated tires with good tread.When driving at a low speed through water, apply light brake pressure with your left foot while the right is still on the accelerator. This builds friction/heat on the brakes pads.Hydroplaning Video
38SNOW: If possible, do not drive in extreme weather conditions DRIVING TECHNIQUES: Gentle acceleration, steering, and braking are keys to vehicle control in snow.ICE:Ice on Bridges:Bridge roadways tend to freeze before other roadways surfaces. Cold air circulates above and below the roadway on bridges and overpasses. So there may be ice even if other areas are clear.Black iceForms in thin sheets. Be extra careful for this type of ice in winter situations.Ice in tire tracksSnow can pack down into ice in the normal driving tracks. Avoid this by moving a little to the right side of the lanedriving in ice and snowSnow and Ice
39ice + snow + hill = no control! Snow and IceRemember breaking distance will always increase in low-traction situations. Slow early and then be ready to slow even more.ice + snow + hill = no control!Can you think of other road types that might interfere with traction while driving?Gravel RoadsLeavesConstruction areas
40Skidding Over- Braking Skid In extreme traction situations, your tires may lose all or part of their grip on the road.SkiddingOver- Braking SkidIf your vehicle doesn’t have an antilock brake system (ABS) and you over-brake, the wheels may stop while you are still moving. To correct this release your brake pedal enough to get your wheels rolling. Does your family car have ABS? how to safely drive in winter
41Skidding 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:Releasing the accelerator or brake pedal pressureQuickly apply and release the brake pedal to slow if your vehicle does not have ABSContinue to look and steer at the path of travel you want to follow.
42OTHER ADVERSE WEATHER CONDISTIONS HOT WEATHER REAR WHEEL SKID: If the rear end of your vehicle starts to skid, you should turn your wheels in the direction of the skid.OTHER ADVERSE WEATHER CONDISTIONS HOT WEATHERYour 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.NEVER remove the radiator cap on a hot engine because the hot liquid inside can scald you. this is why!!!
43COLD WEATHERCarbon 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
