1 Unit 9: Sharing the Road and Handling Emergencies
Vehicle Malfunctions NV Driver Education Curriculum Unit 9: Sharing the Road and Handling Emergencies Presentation 3 of 5 TOPICS: Steering, Brake, and Tire Failure Engine Failure & Vehicle Fire Loss of Forward Vision

2 Most vehicle malfunction can be prevented with proper maintenance.
Pay attention to warning lights Maintain fluid levels Check tire pressure Dash image from: Tire image from: Fluid image from: Retrieved 09/02/11

3 Warning Lights & Gauges
Warning alert lights: When vehicle is first turned on, all lights illuminate Once engine is running, all should go out ** If light stays on it needs attention** Warning gauges: Engine temperature Oil pressure Charging Lights image from: Gauges image from:

4 What to Do if Vehicle Fails
Be prepared for emergencies Steer safely off the road Be visible when stopped Raise hood, tie something white to antenna or hang out window Call for help Remain buckled in the car Lock vehicle doors Female image from: Triangle image from: Retrieved 09/02/11

5 Be Visible When Stopped
Set out flares or warning devices 100 and 200 feet increments behind car On Undivided Highways On Divided Highways Images from: AAA How to Drive Textbook 14th edition 2009 Retrieved 09/02/11 Recommended placement of emergency-warning devices

6 Vehicle Failures There is always a possibility that your vehicle may malfunction. The most serious failure affect: Steering Braking Engine Steering image from: Freeway image from: Fire image from: Retrieved 09/02/11

7 Steering problems should not be solved on the road while driving.
Steering Failure Steering problems should not be solved on the road while driving. Slow down immediately Use flashers to warn others If power steering fails, you will have to work extremely hard to steer the vehicle, but full control will not be lost. Image from: Retrieved 09/02/11 Drivers can usually identify problems, “loose” or difficult steering before a complete failure occurs.

8 Never adjust or move the key ignition while the vehicle is in motion.
Steering Wheel Locks Never adjust or move the key ignition while the vehicle is in motion. If the steering wheel were to lock, slow down the vehicle as quickly as possible by whatever means to avoid losing control. Ignition image from: Steering image from: Retrieved 09/02/11

9 Most common causes of brake failure are wet and overheated brakes.
Rear and front wheels each have a brake system. If total brake failure: Pump the foot brake pedal (with power brakes not effective) Downshift to lower gear Apply parking brake Search for safe place to steer Image from: Retrieved 09/02/11

10 Brake Fade Applying brakes hard over a long period (i.e. driving down hills) overheats brakes, causing them to fade. Temporary brake failure Less effective Stop vehicle to allow brakes to cool Use lower gears to help prevent brake fade Sign image from: Road image from: Retrieved 09/02/11

11 Driving through water can temporarily reduce brakes’ effectiveness
Wet Brakes Driving through water can temporarily reduce brakes’ effectiveness Drive slowly in puddles Gently apply brakes as you drive though water Friction will generate heat Test brakes as leave water Riding the brake will dry brakes (left foot lightly on brake, as right foot slowly accelerates) Black car image from: Flooded image from: Retrieved 09/02/11

12 Stuck Accelerator If accelerator is stuck: Attempt to jar it free
Use toe to lift pedal Step on pedal repeatedly Apply brakes Shift into Neutral (to remove power from the wheels) Turn the off vehicle (last resort) will lose power steering Accelerator image from: Gear image from: Ignition image from: Retrieved 09/02/11

13 Engine Failure Usually little warning when engine sputters or stops
If engine stops suddenly: Shift into Neutral Move out of traffic Turn on flashers Do not brake Try to re-start the engine Gauge image from: Males image from: Retrieved 09/02/11

14 Stalled on Railroad Tracks
If a train is approaching: Abandon vehicle Immediately Run at a 45-degree angle away from the tracks, towards the oncoming train (to avoid being hit by debris when the train collides with your vehicle). If not approaching: Try restarting your vehicle Shift into Neutral and push vehicle off tracks Image from: Retrieved 09/02/11 A train traveling at 55 mph may travel more than one mile after applying the emergency brakes.

15 Overheated Engine When the temperature gauge indicates an overheated vehicle: Use heater to draw heat away from engine if you cannot pull off the road immediately. Turn off air conditioning During stops, shift to Neutral and press accelerator gently Pullover, turn off engine Open the hood of the car to cool engine Gauge image from: Car image from: Retrieved 09/02/11

16 Engine Fires Most engine fires are caused by either an electrical or fuel problem. Handle quickly and properly: Get your car off the road Turn off the engine Move away from the vehicle At least 100 feet away Do not open hood Image from: Retrieved 09/02/11 If fire is in rear of the vehicle, very hazardous, gas tank may explode.

17 Tire Wear Tires wear quicker with poor maintenance and road conditions: Under or over inflated Unbalanced wheels Poor alignment Abrupt braking Sharp steering Bumps and potholes Dash image from: Pothole image from: Retrieved 09/02/11

18 Tire Blowout A blowout occurs when a tire suddenly loses air pressure
Tire hits object in road or a pothole Driver fails to maintain proper tire pressure Tire image from: Silver car image from: Retrieved 09/02/11

19 What to Do - Tire Blowout
Front tire blow out Vehicle quickly pulls in direction of blowout Back tire blow out Rear end will slide around or “fishtail” What to do: Hold steering wheel firmly Ease off accelerator Do not brake Look and steer to safety, off the road Red car image from: Blue car image from: Accident image from: Retrieved 09/02/11 Tire blow out causes accident

20 Changing a Tire Changing a tire on a roadway is dangerous and can be risky. Find a safe place, completely off the road Call for help Professionals know best If you change the tire, use proper tools and safety precautions Triangle image from: Family image from: Retrieved 09/02/11

21 Loss of Forward Vision Loss of forward vision may be caused by:
Headlight failure Hood flies open Look though side window Pull over immediately Windshield splashed with dirt Turn on wipers Screaming image from: Dirty image from: Retrieved 09/02/11

22 Headlights Failure If your headlights flicker or fail take immediate action Turning on the parking lights, emergency lights, or hazards Use turn right turn signal and move to the shoulder of the road Check fuses or fuse clips Image from: Fuse image from: Retrieved 09/02/11
