Title: Handling Emergencies


1
Chapter 13
  • Handling Emergencies

2
Chapter 13 Overview
  • Chapter 13 discusses driving emergencies caused
    by vehicle malfunction and driver error. You
    will learn how to handle emergencies and what
    actions to take after a collision.

3
13.1 Vehicle Malfunctions
  • This section is devoted to common vehicle
    malfunctions including tire failure, brake
    failure, accelerator malfunction, engine failure,
    and steering failure. These malfunctions are
    identified and appropriate reactions are
    described. Loss of forward vision, vehicle
    fires, and stalling on railroad crossings are
    also addressed.
  • Section 1 Objectives Following this section, I
    will be able to
  • 1. List actions to take if a tire blows out.
  • 2. List the proper steps to follow if the brakes
    fail.
  • 3. Explain what to do if your accelerator
    sticks.
  • 4. Describe what to do in case of steering
    failure.

4
13.1 Vocabulary
  • At the conclusion of this section, I will be able
    to define
  • 1. blowout
  • 2. brake fade
  • 3. jack
  • 4. lug nuts

5
Vehicle Malfunctions
  • Most vehicle malfunctions can be prevented
    through proper maintenance. If you detect a
    warning sign, have the necessary repairs made
    promptly.
  • Some vehicle equipment can malfunction without
    any warning thus causing an emergency. Think
    ahead of what you might do in the event of an
    emergency. Being prepared can help reduce your
    risk of serious trouble in traffic.

6
Tire Failure
  • Abrupt braking and sharp steering shorten tire
    life.
  • Hitting bumps, potholes, or driving on poor
    roadway surfaces can damage tires.
  • Unbalanced wheels and poor alignment can cause
    tires to wear unevenly.
  • Underinflation and overinflation cause tire wear.

7
Blowout
  • Occurs when a tire suddenly loses air pressure.
  • If front tire blows out, steer firmly against the
    pull of the vehicle.
  • Especially dangerous is the left front tire
    blowing out as it will pull you toward the
    oncoming traffic.
  • If rear tire blows out, handle it like you would
    a skid (turn in the direction of the skid).

8
Blowout
  • Follow these steps when a tire blows out
  • 1. Grip the steering wheel firmly.
  • 2. Ease up on the accelerator to slow down. Do
    not brake as it may cause you to serve.
  • 3. Check the traffic situation as you gain
    control of your vehicle.
  • 4. Drive off the roadway slowly, braking gently.
  • 5. Turn on hazard flashers. Drive slowly until
    you find a safe location to stop.

9
Changing a Tire
  • 1. Park on level area. Turn on hazard lights
    and put gearshift into PARK.
  • 2. Set the parking brake.
  • 3. Block the wheel diagonally opposite the flat
    tire.
  • 4. Have passengers get out and stand in a safe
    place.
  • 5. Get out the spare tire, jack, and lug wrench.
  • 6. Assemble the jack and position it under the
    vehicle.
  • 7. Jack up the vehicle partway. The tire should
    still touch the ground so that it will not turn.
  • 8. Remove the wheel cover and loosen the lug
    nuts.

10
Changing a Tire
  • 9. Jack up the tire until it is completely off
    the ground.
  • 10. Using the lug wrench, remove the lug nuts.
  • 11. Remove the wheel with the flat tire and
    place to the side.
  • 12. Mount the spare tire.
  • 13. Replace and tighten the lug nuts.
  • 14. Lower the vehicle and remove the jack.
  • 15. Tighten the lug nuts using the lug wrench.
  • 16. Leave the wheel cover off as a reminder to
    fix the flat tire. Put tire changing equipment
    in the trunk and remove the blocks.

11
Brake Failure
  • Vehicles are required to have a two-part braking
    system. If one part fails then there will still
    be brakes for two wheels.
  • If both parts fail, you will have no foot braking
    ability.
  • The brake warning light will signal brake
    failure.

12
Total Brake Failure
  • This rarely happens but when it does, it is
    usually when you are braking for a hard stop.
  • If it does occur, follow these steps
  • 1. Pump the brakes. It may be enough to restore
    enough brake pressure to slow you down.
  • 2. Downshift to a lower gear which uses engines
    braking power.
  • 3. Pull and hold the parking-brake release lever
    out or the button in the off position. Apply
    the parking brake. You can quickly release the
    parking brake if the vehicle starts to skid.
  • 4. Search for an open zone. As a last resort,
    rub your wheels against a curb to slow down. If
    a collision is unavoidable, go for a sideswipe
    rather than a head-on collision.

13
Power Brake Failure
  • If you have power or power assisted brakes and
    they fail, it is usually because of the loss of
    power to your brakes.
  • The power stops if your engine stops.
  • The brakes will still work, you will just have to
    push the brake pedal a lot harder.

14
Other Brake Failures
  • Brake fade- when brakes overheat as a result of
    continuous hard braking. (Let them cool off)
  • Water- driving through water can cause your
    brakes to not work properly. (After leaving the
    water, gently apply the brake to cause friction
    which will help dry out the brakes.)

15
Accelerator Malfunctions
  • Broken spring- pedal does not respond and may be
    flat on the floor. Shift to NEUTRAL, activate
    the hazard lights, check traffic and brake safely
    to the side of the road. Do not use the vehicle
    until this problem is fixed.
  • Stuck accelerator- if engine does not return to
    idling speed when you let up on the accelerator.
    Follow these steps to counteract this situation
    Kick the side of accelerator pedal apply the
    brakes choose an escape route shift to neutral
    if you are going into a sharp curve follow your
    identified escape path off the roadway turn off
    the ignition once you are off the roadway.

16
Accelerator Malfunctions
  • Put your toe under accelerator pedal and try to
    lift it up. Never reach down with your hand to
    lift the pedal while driving.
  • After stopping, check for obstructions, tap the
    accelerator repeatedly. Check accelerator pedal
    for a broken spring. Fix before driving.

17
Engine Failure
  • Follow these steps if you have engine failure
  • 1. Shift to NEUTRAL if engine sputters or stops.
  • 2. Move out of traffic to nearest shoulder.
    Activate hazard lights. Do not brake.
  • 3. Try to restart the engine while moving. If
    it starts, shift into gear and proceed. If it
    does not start, continue on to shoulder of road.
    Try to start again.
  • 4. If engine fails to start, raise the hood and
    leave your flashers on. Go or call for help.

18
Flooded Engine
  • Follow these steps to start flooded engine
  • 1. Hold accelerator pedal to floor to allow air
    in and to clear excess fuel from engine.
  • 2. While holding down accelerator, turn engine
    switch on for five seconds. If engine does not
    start, wait a few minutes and try again.
  • 3. When engine starts, release accelerator
    gradually to help clear excess fuel from the
    engine.

19
Overheated Engine
  • Follow these steps if your engine overheats
  • 1. Turn off the air conditioner.
  • 2. Turn on the heater to draw heat from the
    engine. This will help lower engine temperature.
  • 3. During stops, shift to NEUTRAL. Press the
    accelerator pedal gently to speed up the engine
    slightly to help it cool down.
  • 4. If temperature gauge or light points to hot,
    move to safe place. Turn off engine, lift hood,
    let engine cool. Do not add water until engine
    has cooled.

20
Steering Failure
  • If your steering totally fails, follow these
    steps
  • 1. Use your horn and hazard flashers to
    communicate your emergency.
  • 2. Stop as quickly and smoothly as possible.
    Lift your foot from the accelerator. Do not
    brake as this could put you into a skid. Use a
    quick on-off action of the parking brake with the
    release in the off position.
  • 3. Shift to a lower gear.

21
Power Steering Failure
  • Occurs when the engine dies, when the power
    steering fluid level is low, or when the drive
    belt slips or breaks.
  • The steering mechanism still works, but you will
    have to exert more effort to steer.

22
Loss of Forward Vision
  • Hood flies up- Follow these steps
  • 1. Look through the crack below the open hood
    (if possible) and steer to a safe place. Check
    your rear zone.
  • 2. If you cannot see under the hood, roll down
    your window. Look in the direction that you are
    driving.
  • 3. Turn on the hazard flashers. Pump your
    brakes gently to warn other drivers of your
    emergency.
  • 4. Slow down and drive out of the traffic flow
    to a safe location.

23
Headlights Fail
  • Follow these steps if your headlights fail
    entirely
  • 1. Turn on your right turn signal to light up an
    escape path to the right.
  • 2. Immediately slow down and bring your vehicle
    to a safe stop.
  • 3. Try your dimmer switch, parking lights, and
    hazard flashers. Some circuits might still work.
    If so, these lights to help you drive off of
    roadway to a safe location.
  • 4. Use light from street lights, signs,
    buildings, or other vehicles to help you see.
    Move to a safe location. Use your flashlight to
    check fuses or fuse clips. If necessary, replace
    or reseat the fuse before proceeding.

24
Splashed Windshield
  • If your windshield gets splashed with snow,
    slush, or mud, turn on your windshield wipers
    immediately.
  • Slow down and try to maintain your path of travel
    until you regain visibility.
  • If you anticipate your windshield being splashed,
    turn your wipers on before you lose your vision.

25
Vehicle on Fire
  • A vehicle fire can be very dangerous. It can
    involve fuel oil, grease, ordinary combustibles,
    electrical equipment, or a combination of
    sources.
  • Carry an A-B-C type fire extinguisher that is
    designed to control such fires.
  • Notify the fire department of any vehicle fires.

26
Engine Compartment Fire
  • Most vehicle fires start in the engine
    compartment. Follow these steps in case of fire
  • 1. Quickly steer vehicle off roadway to a safe,
    open area. Stay away from buildings and service
    stations. Turn off the ignition.
  • 2. Have passenger move at least 100 feet away
    from the vehicle.
  • 3. Estimate how serious the fire is. You might
    see smoke and flames around the hood. Dont open
    the hood.

27
Engine Compartment Fire
  • If you think the fire is small enough to control
    and you have an A-B-C type fire extinguisher,
    follow these steps
  • 1. Use gloves or a rag to protect your hands as
    you open the hood. Turn your face away to
    protect it from the flames and heat. Carefully
    open the hood.
  • 2. Direct the extinguisher on the fire. Water
    will not put out oil and fuel fires and can
    spread the fire.
  • 3. Never try to disconnect the battery.
  • Reminder If fire occurs, turn off the engine
    and get passengers out and away from vehicle.

28
Passenger Compartment Fire
  • A passenger compartment fire usually is caused by
    a carelessly handled match or burning tobacco
    product.
  • Pull off the road.
  • Use water or fire extinguisher to completely put
    out the fire. Upholstery fires often restart.

29
Vehicle Fires
  • Each year drivers are surprised to see their
    vehicles go up in smoke shortly after the vehicle
    is parked. The catalytic converter, located
    underneath the vehicle, produces a great deal of
    heat as it decreases exhaust emissions. Heat
    from the catalytic converter, which can reach
    1,200 degrees, can ignite combustible
    substancessuch as leaves or dry grass. Once a
    fire starts underneath a vehicle, it does not
    take long for the vehicle to catch fire.

30
Vehicle Stalls on Railroad Tracks
  • Check to make sure no train is coming. Try to
    restart the vehicle. If the engine floods, hold
    the accelerator to the floor as you restart the
    engine.
  • 2. If you cannot restart the engine, have
    passengers leave the vehicle. Have one person
    watch for trains and have others help you.
  • 3. Shift to NEUTRAL and push the vehicle off the
    tracks.
  • 4. If train is coming, abandon your vehicle.
    Move away from the tracks in the direction the
    train is approaching.

31
Review It
  • 1. What actions should you take if a tire blows
    out?
  • 2. What should you do if the brakes fail?
  • 3. What actions should you take if the
    accelerator sticks?
  • 4. What actions should you take if your steering
    fails?

32
13.2 Driver Errors
  • This section focuses on what to do if your
    vehicle runs off the roadway and how to use
    emergency serving.
  • Section 2 Objectives Following this section, I
    will be able to
  • 1. Describe how to return to the roadway if your
    vehicle runs off the roadway.
  • 2. Explain how to use an emergency swerve.

33
13.2 Vocabulary
  • At the conclusion of this section, I will be able
    to define
  • 5. countersteer.

34
Driver Errors
  • Driver errors (i.e., inexperience, lack of
    attention, poor decisions) cause many more
    emergencies than do vehicle malfunctions.
  • Developing automatic responses to emergencies is
    critical to the driving task.
  • A fatal one-vehicle collision can occur if a
    driver turns the steering wheel too fast and too
    soon to return to the roadway, or does not
    countersteer after returning to the roadway. As
    a result, the vehicle can roll over, cross the
    roadway, and slide off the left side of the
    roadway.

35
Off-Road Recovery
  • Follow these steps for a safe off-road recovery
    (see pictures on p. 276)
  • 1. Hold the steering wheel firmly on the top
    half with both hands. The greater the drop-off,
    the more control you are going to need. Keep
    your vehicle heading straight toward your target.
    Check for upcoming obstructions.
  • 2. Let up on accelerator and brake gently to 5
    or 10 mph. Avoid hard braking.
  • 3. Straddle the roadway edge with your vehicle.
  • 4. Select a place to return to the roadway where
    the shoulder is nearest the level of the roadway.

36
Off-Road Recovery
  • 5. Signal, check for traffic and your blind
    spot, and return to the roadway.
  • 6. Steer 1/8 to ΒΌ of a turn toward roadway to
    return. If the drop off is severe, slow more and
    turn very sharply to get back onto the pavement.
  • 7. Countersteer (steer in the opposite
    direction) sharply as soon as the front tire
    touches the roadway.
  • 8. Center the vehicle in the lane and
    reestablish your target. Cancel your signal and
    accelerate to match the flow of traffic.

37
Need to Swerve
  • The need for an emergency swerve is almost always
    the result of the driver being surprised.
    Eliminating the surprise will go a long way
    toward eliminating the need for an emergency
    swerve. Two things that help drivers eliminate
    surprises are identifying a clear path of travel
    and identifying a line-of-sight restriction that
    prevents you from seeing something that can come
    into your path. A closed front zone requires a
    reduction of speed. By reducing speed you give
    yourself more time to make slight prevention
    actions rather than executing an emergency swerve.

38
Emergency Swerving
  • Use only as a last measure to avoid a collision.
  • Swerve only when you think that braking will not
    prevent a collision.
  • At speeds over 30 mph, you can usually swerve to
    a new path in less distance than it would take to
    stop safely.

39
The Stop-Swerve Decision
  • Follow these steps if you decide to swerve
  • 1. Identify the escape path.
  • 2. Grip the steering wheel firmly and turn the
    wheel sharply in the direction of the swerve.
  • 3. Countersteer to stabilize your vehicle.
    Straighten the wheel and continue to steer in
    your path.
  • As speed increases you have less time to
    swerve. At 40 mph you have about 2 seconds to
    swerve. At 60 mph you have just 1 second to
    swerve.

40
Avoiding Emergency Swerves
  • A driver can develop three behaviors into habits
    that will serve as an insurance policy against
    driving into situations requiring an emergency
    swerve. First, keep at least three seconds of
    following distance. This will eliminate the
    swerves caused by vehicles in front stopping
    abruptly. Second, use the lane positioning and
    speed reductions in response to identifying
    closed zones and line-of-sight restrictions.
    Third, never put the vehicle into a space unless
    you can see that the space is empty.

41
Review It
  • 1. How should you return safely to the roadway
    if your vehicle runs off the roadway?
  • 2. Under what conditions should you make an
    emergency swerve?

42
13.3 Roadway Hazards
  • This section identifies roadway hazards,
    including potholes and objects in the roadway,
    and how to avoid them. Instructions for dealing
    with sharp curves are also included. The lesson
    also focuses on what to do if a vehicle goes into
    deep water.
  • Section 3 Objectives Following this section, I
    will be able to
  • 1. Describe how to minimize vehicle damage
    caused by potholes.
  • 2. Explain what to do if you enter a curve too
    fast.
  • 3. Tell how to escape from a vehicle that is
    sinking in water.

43
13.3 Vocabulary
  • No words for this section.

44
  • What kind of roadway emergencies have you
    observed as passengers?
  • Based upon what you described, what would be
    suggestions as to how these emergencies might
    have been prevented?

45
Roadway Hazards
  • Unusual and unexpected roadway hazards can cause
    you to lose control of your vehicle thus
    resulting in emergency situations.

46
Potholes in the Roadway
  • Potholes have sharp edges that can severely
    damage your tires.
  • If you hit a pothole at a fast speed you might
    lose control of your vehicle.
  • Watch for and avoid hitting potholes whenever
    possible.
  • If you cant avoid hitting a pothole, stay in
    your lane and slow down.

47
Sharp Curve
  • Take these steps if you enter a curve too fast
  • 1. Brake gently as soon as you realize you are
    going too fast. If you are not yet into the
    curve, brake more firmly. If you are already in
    the curve, brake, but do not lock the wheels.
  • 2. About halfway through the curve, find your
    target and accelerate gently to stabilize your
    vehicle.

48
Object on the Roadway
  • Any object in the road can be a hazard.
  • Avoid all objects in the roadway if at all
    possible.
  • Only straddle an object if you are sure it will
    clear the vehicle.
  • Avoid swerving left across the center line as you
    could encounter oncoming traffic.
  • Drive over an object only as a last resort.

49
Vehicle in Deep Water
  • Do not attempt to drive through deep water on the
    roadway. Turn around or take another route.
  • Take these actions if your vehicle goes into deep
    water
  • 1. Open window that is most out of the water.
    Power windows may short out so open these windows
    immediately.
  • 2. Unfasten your safety belt. Check your
    passengers and have them unfasten their safety
    belts.
  • 3. Exit promptly through the open window.

50
Vehicle in Deep Water
  • If windows do not open, attempt to exit through a
    door. It may open slowly due to pressure from
    the outside. As the water enters the vehicle it
    will equalize and then you can open the door.
  • If vehicle is fully submerged under water, there
    will be a pocket of air at the highest point.
    Get a full breath of air while locating a window
    or door that is facing up. Open the window or
    door and leave your vehicle.
  • If trapped in your vehicle underwater, turn on
    your headlights as this may help rescuers to find
    your vehicle more quickly.

51
Review It
  • 1. What should you do if you see a pothole in
    your path of travel?
  • 2. What actions should you take if you enter a
    curve too fast?
  • 3. How should escape a vehicle that is sinking
    in deep water?

52
10.4 Collisions
  • This section focuses on how to avoid collisions
    and what to do if a collision occurs. It also
    presents follow-up steps needed after a
    collision.
  • Section 4 Objectives Following this section, I
    will be able to
  • 1. Explain how to avoid or minimize head-on,
    side impact, and rear-end collisions.
  • 2. List the immediate steps to take if a
    collision occurs.
  • 3. Describe other follow-up steps needed after a
    collision.

53
13.4 Vocabulary
  • No words for this section.

54
Minimizing Effects of a Collision
  • Knowing how to react in advance can lessen the
    effects of a collision. If a collision is about
    to occur, act as follows
  • 1. Do not give up. Keep control of your
    vehicle. Any change of speed or direction that
    lessens the impact will help.
  • 2. Steer for something soft if you leave the
    roadway. Look for bushes or open fields.
  • 3. Avoid objects such as trees or parked cars.
  • 4. Get yourself and passengers out of and away
    from your vehicle if there is a chance of another
    vehicle colliding with your vehicle.

55
Threat of a Head-on Collision
  • Serious injury and/or death are more likely to
    occur with a head-on collision as it has the
    greatest force of impact of any collision.
  • Follow these steps if threatened with a head-on
    collision
  • 1. Maintain vehicle control. Brake hard but
    avoid locking the wheels. Slowing lessens the
    impact and gives the other driver time and space
    to recover.
  • 2. Blow the horn and flash the headlights.
    Continue braking and move to the right .
  • 3. Steer right toward the shoulder. Do not
    steer to the left. The other driver will more
    than likely try to recover to the correct lane.
    Be prepared to drive entirely off of the roadway,
    if necessary.

56
Threat of a Side-Impact Collision
  • Take these steps to avoid or lessen the effect of
    a side-impact collision
  • 1. Brake or accelerate quickly.
  • 2. Blow the horn to alert the other driver.
  • 3. Change lanes or swerve away from the impact.
    Be aware of what is going on around you.
  • An impact to the passenger compartment often
    causes a second collision between passengers and
    the inside of the vehicle.

57
Threat of a Rear-End Collision
  • Take these actions if threatened with a rear-end
    collision
  • 1. Flash your brake lights early to alert the
    driver behind you.
  • 2. Check your front zones for open space. You
    may be able to move forward to avoid or minimize
    the collision.
  • 3. If the intersection is clear, accelerate to
    give the other driver more space. If your path
    is not clear, turn right.
  • 4. If the collision is unavoidable, release your
    brakes just before the collision occurs as it
    will help reduce the impact. Brake immediately
    after the collision to avoid sliding into another
    traffic lane.
  • Maintain at least a 3 second following
    distance as this will provide you with space to
    help minimize or avoid a rear-end collision.

58
If You Have a Collision
  • If you collide with another vehicle, a
    pedestrian, or someones property, you are
    legally required to follow these steps
  • 1. Stop immediately- move your vehicle to the
    side of the road out of the way of traffic if
    possible turn off ignition if you damage a
    parked car and cannot find the owner, write your
    name, address, and phone number on a note and
    leave it under the windshield wiper notify the
    police.
  • 2. Aid to the injured- never move an injured
    person unless there is danger of fire or another
    collision. Send for paramedics administer first
    aid (if trained) for severe bleeding, shock, or
    breathing stoppage.
  • Good Samaritan Law

59
If You Have a Collision
  • 3. Prevent further damage- set flares (if
    available) 100 ahead and behind the collision
    site (500 if high-speed traffic). Or, have a
    person direct traffic around the collision site.
    Do not put yourself or others in danger while
    directing traffic.
  • 4. Send for police- call police if anyone is
    injured or killed. Some states require the
    police to be called on any collision.
  • 5. Exchange information- get and provide the
    following information with drivers involved in
    the collision names, addresses, drivers license
    numbers, license plate numbers, and names and
    addresses of insurance companies. Also, get
    names and addresses of passengers, position they
    were sitting in and the extent of their injuries.
    You are responsible for gathering this
    information.

60
Additional Steps After a Collision
  • 1. Record witnesses names and addresses make a
    sketch of the collision scene or take a photo
    record date, time, weather, and driving
    conditions note what hospital people are being
    taken to write down the name and badge number of
    the police officer at the scene of the collision.
  • 2. Provide police with accurate, honest facts.
    Never argue over blame or admit to blame. Stay
    at the scene until you are told you can leave.
    If necessary, take your vehicle to a repair shop.
    You will usually need at least two repair
    estimates for insurance purposes. Keep all bills.

61
Additional Steps After a Collision
  • 3. You must file a written report if someone was
    killed or injured or if the property damage
    exceeds a set amount. Some states require this
    to be finished within 24 hours. You must also
    produce proof of financial responsibility by
    showing your insurance card that shows your
    current coverage. Notify your insurance agent
    promptly. Some companies might refuse to pay
    your claim if your insurance agent has not been
    notified within the time frame prescribed in your
    policy.
