Contemporary (BGE) Mirror Settings Rear Mirror View 15º Topic 3 Lesson 3 SIDE MIRRORS ARE SET 15 DEGREES OUT GLARE FROM OTHER VEHICLE’S HEADLIGHTS IS REFLECTED AWAY FROM THE DRIVER 2

Headlight Alignment and Speed PROPERLY ALIGNED LOW BEAM HEADLIGHTS T – 8.3 Topic 1 Lesson 2 lighted area above road 300 to 500 feet illuminated roadway 100 to 150 feet The Code of Virginia requires The Code of Virginia requires that you use your headlights from sunset to sunrise and during inclement weather, such as rain, fog, snow, or when you use your windshield wipers. At twilight, when the sun light begins to fade, turn your headlights ON. This will make your vehicle more visible to others.  100 – 150 Feet Beam Hits Roadway Ahead  300 – 500 Feet Illuminates Area Ahead In The Road  MAXIMUM SAFE SPEED OF 40 TO 45 MPH Should Be Able To Stop In The Distance The Roadway Is Illuminated 3, 4

Headlight Alignment and Speed PROPERLY ALIGNED HIGH BEAM HEADLIGHTS T – 8.4 Topic 1 Lesson 2 illuminated roadway 300 to 500 feet lighted area above road 500 to 1800 feet SWITCH TO LOWER BEAMS 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 12 The Beam Hits The Roadway 300 To 500 Feet Ahead Illuminates The Area Above The Road 500 To 1800 Feet Ahead OVERDRIVING YOUR HEADLIGHTS VEHICLE IS UNABLE TO STOP IN THE DISTANCE ILLUMINATED BY THE HEADLIGHTS

BACKED UP TO GUARD RAIL  GREATLY REDUCES THE LIKELIHOOD OF THE VEHICLE BEING HIT BY OTHER VEHICLES.  SAFER POSITION WHEN STOPPED IN BAD WEATHER OR VEHICLE FAILURE 2

ELECTRONIC STABILITY PROGRAM (ESP) Analyzes Vehicle Steering If Vehicle Responds Incorrectly The Brakes Are Selectively Applied To Help The Driver Regain Control TRACTION CONTROL SYSTEM When Accelerating Brake Sensors Come On If Wheel Begins To Spin SUSPENSION CONTROL SYSTEM adjusts vehicle balance by adjusting the fluid or air pressure of shock absorbers or struts when weight is suddenly shifted to a wheel ANTI LOCK BRAKING SYSTEM Allows The Driver To Apply Max Braking Power Without Steering Control Automotive Technology Topic 4 Lesson 2 3

TRACTION STATIC – Vehicle Is Not Moving. Max Control Between Tire & Roadway Surface ROLLING – Vehicle Is Moving SLIDING – Vehicle Is Moving But Tires Are Not Rolling. Loss Of Traction While The Vehicle Is In Motion TRACTION is the grip between the tires & the road surface which allows a vehicle to start, stop or change directions ________________________________________________________________________________________________________________________________ Topic 5 Lesson 2 Most Driver-induced Skids Are Caused By: Excessive Speed Coupled With Excessive Steering Input Or Improper Braking When Turning Loss Of Traction Also Occurs With These Driver’s Actions At Normal Speeds On Ice/Snow Or On Sand, Gravel, Or Water 1, 2

TRACTION LOSS DURRING FRESH RAIN -First 15 Minutes After It Starts Raining Is Very Dangerous - Water Dirt Oil & Rubber Combine On The Roadway Surface - Makes Roads Extremely Slippery 3

Causes of Traction Loss Causes of Traction Loss BRAKES UNEVENLY ADJUSTED Brakes Pulling In One Direction Or The Other Can Cause A Skid Out Of Alignment TIRES WITH WORN TREAD -Tread Is Necessary For Traction In Wet Weather -Worn Tread Cannot Channel Water Effectively & Will Result In Traction Loss & Hydroplaning In Wet Weather T – 8.37 Topic 5 Lesson 2 UNEVEN TIRE PRESSURE - Similar To The Effects Of Unevenly Adjusted Breaks The Vehicle May Pull To One Side To The Other & Result In A Skid - Spend More Money On Gas 4

Traction Loss to Front Tires THE DRIVER IS STEERING LEFT BUT THE VEHICLE IS CONTINUING TO MOVE STRAIGHT. THIS RESULTS FROM LOSS OF TRACTION TO THE FRONT TIRES & IS CALLED UNDERSTEER Actual Path of Travel Intended Path of Travel T – 8.43 Topic 5 Lesson 3 front tires SLIDE rear tires PUSH 8

To Correct Front Traction Loss Targeted Path of Travel Lift Eyes to Targeted Path of Travel Topic 5 Lesson 3 9, 12 Actual Path of Travel Intended Path of Travel First response should be to RELEASE the accelerator or break Look & steer toward your INTENDED PATH OF TRAVEL. Abs breaks shift weight to the FRONT to regain traction Quick JAB to breaks also shifts weight Avoid this situation you should BREAKE before entering a curve or turn and avoid OVER STEERING ABS is helpful in UNDER STEER traction loss & traction control systems are helpful in OVER STEER traction loss

To Correct Front Traction Loss Actual Path of Travel Intended Path of Travel Drivers intended path of travel is STRAIGHT but the rear of the vehicle is SLIDING RIGHT. Drivers intended path of travel is STRAIGHT but the rear of the vehicle is SLIDING RIGHT. This results from loss of traction to the REAR tires & is called OVER STEER. This results from loss of traction to the REAR tires & is called OVER STEER. RELEASE the brake or accelerator. RELEASE the brake or accelerator. Look & steer toward your INTENDED PATH OF TRAVEL. Look & steer toward your INTENDED PATH OF TRAVEL. Very light progressive acceleration will help shift weight to the REAR to help regain traction. Very light progressive acceleration will help shift weight to the REAR to help regain traction. 10, 11
