Tips for Winter Driving
2
Preparing the Vehicle
  • Check the electrical system- make sure the
    battery is strong enough for cold-weather starts,
    check the ignition wires spark plug wires, make
    sure all lights are functioning correctly
  • Brake system- have your brakes checked regularly
    and do not delay necessary maintenance
  • Tires- the amount of traction that exists between
    the tires and the road determines how well a
    vehicle will handle, check for worn tires, have
    the tread depth checked

3
  • Exhaust system- have your exhaust system checked
    for leaks or defects, carbon monoxide is odorless
    and can quickly cause death
  • Heating Cooling system- make sure that the
    cars cooling system has antifreeze that will
    withstand temperatures of -30 to -40 degrees,
    check to be sure that the reservoir is filled to
    the line indicating full
  • Windshield wipers washer fluid- winter driving
    presents unique window clearing issues, be sure
    that you have wiper blades that clear the
    windshield without streaks, check washer fluid
    and be sure it is good to -20 degrees, cont.

4
  • Wipers (cont.)- to prevent damage to the blades
    and/or wiper motor- be sure the wipers are free
    from ice and snow and turned off before starting
    the car
  • Winter driving kit- it is advisable to have the
    following items in your vehicle during winter
    months

5
  • Gas tank- keep your gas tank at least half full
    to avoid gas line freeze-up and to give extra
    weight to your vehicle
  • Warming up- never let your car run in an enclosed
    area, as this will produce carbon monoxide-
    start your car and turn the heater on for a
    minute or two, this will prevent moisture from
    forming on your windshield when warm air hits
    cold glass

Driving Tips
  • Clean all snow ice from the entire vehicle
    hood, trunk, lights, windows. Snow left on any
    of these areas increases the possibility that
    visibility will be affected when the vehicle is
    in motion.
  • Warm up the car as described above.
  • Avoid driving while youre fatigued.
  • Use your seatbelt everytime.
  • Traction is greatest just before just before the
    wheels spin. Gentle pressure on the accelerator
    pedal when starting is the best method for
    retaining traction and avoiding skids.
  • Keep your speed low, and your headlights on low
    beams

8
  • Remember- Do not use cruise control when driving
    on any slippery (wet, ice, snow, sand) surface.
  • The stopping distance required on ice at 0F is
    twice the amount required at 32F.
  • Normal following distances for dry pavement
    (three to four seconds) should be increased to 8
    to 10 seconds when driving on icy, slippery
    roads.
  • Keep your lights and windshield clean. (Even if
    it means you have to stop get out to take care
    of this.
  • Dont pass snow plows and salt/sand trucks. The
    drivers have limited sight and the road ahead
    will probably be worse than the road behind it.

9
  • When approaching a hill, observe how other
    vehicles are reacting and keep for enough behind
    the vehicle immediately ahead so that others will
    have to slow down or stop.
  • Gently increase your speed at or near the bottom
    of the hill in order to gain momentum to crest
    the hill.
  • Minimize brake use on slippery surfaces. If
    needed, apply brakes gently, avoid hard braking.
  • Dont assume your vehicle can handle all
    conditions. Even 4-wheel and front-wheel drive
    vehicles can encounter trouble on winter roads.

10
Visibility
  • Coping with winter's visibility problems must
    begin before you even get behind the wheel. It
    includes allowing enough time to clear any snow,
    ice, or frost from the windowsall the
    windowsinside and outside.
  • You need 360-degree visibility, and don't forget
    the mirrors and wipersfront and rear, if your
    vehicle is so equipped. Use your fingers to break
    off any accumulated ice on the blades and wipe
    them clean. Be sure the wiper nozzles are clean,
    too. A long pin works well for that purpose.
  • Metal-edged ice scrapers work best, if you can
    find them. If not, a paint scraper with a short,
    strong blade can make an acceptable substitute.
    Credit-card-like pocket scrapers, or credit cards
    themselves, do an admirable job on interior
    frost.
  • Be sure to remove snow from all the lights and
    from the hood and heater air inlet slits (usually
    at the base of the windshield). Otherwise you
    might find your initially clear windshield fully
    frosted over two or three minutes after you drive
    away.
  • When entering the vehicle, kick as much snow off
    of your feet as possible. Snow tracked inside the
    vehicle can contribute to window fogging.
  • Ensure the heater and defroster are working
    properly.

11
Accelerating
  • Accelerate slowly to reduce wheel spin. If
    starting from a standstill on slick snow or ice,
    start in second gear if you have a manual
    transmission so the vehicle is less likely to
    spin the tires. The automatic transmissions on
    some vehicles have a winter mode that
    automatically starts in a higher gear.
  • Reduce your speed and drive smoothly. In slippery
    conditions, tires lose their grip more easily,
    affecting all aspects of your driving braking,
    turning, and accelerating. The key is to drive as
    smoothly as possible, avoiding sudden actions or
    rapid movements of any kind. Drive as if you have
    a full cup of coffee on the dash board or a bowl
    of water in your lap and don't want to spill any.

12
Steering
  • Perform one action at a time when accelerating,
    braking, and turning. Asking a vehicle to do two
    things at once--such as braking and turning, or
    accelerating and turning--can reduce your
    control. When taking a turn, for instance, slowly
    apply the brakes while the vehicle is going
    straight. When it's at the right speed to take
    the turn, let up on the brakes and smoothly turn
    the steering wheel. After you're through the
    turn, slowly depress the accelerator to regain
    your speed.
  • Avoid sudden actions when cornering. A sudden
    maneuver--such as hard braking, a quick turn of
    the steering wheel, sudden acceleration, or
    shifting a manual transmission--can upset a
    vehicle's dynamics when it's taking a turn. In
    slick conditions, this can cause it to more
    easily go out of control.

13
Braking
  • Allow longer braking distances. Plan on starting
    your braking sooner than you normally would in
    dry conditions to give yourself extra room, and
    use more gentle pressure on the brake pedal.
  • Don't lock your wheels when braking. Locked
    wheels can make the vehicle slide or skid. If you
    have a vehicle without an antilock braking system
    (ABS), you may need to gently apply the brakes
    repeatedly to avoid having them lock up the
    wheels. If your vehicle has ABS, simply depress
    the brake pedal firmly and hold it down. ABS
    typically sends a vibration or pulsing sensation
    through the brake pedal. If you feel this, don't
    let up it's normal.

14
What to do in Skids
  • If your rear wheels skid
  • Take your foot off the accelerator.
  • Steer in the direction you want the front wheels
    to go. If your rear wheels are sliding left,
    steer left. If your rear wheels are sliding
    right, steer right.
  • Make slow deliberate motions with the steering
    wheel.
  • If you have standard brakes, pump them gently.
  • If you have anti-lock brakes (ABS) do not pump
    them. Apply steady pressure.

15
  • If your front wheels skid
  • Take your foot off the accelerator shift into
    neutral, but dont try to steer immediately.
  • As the wheels skid sideways, they will slow the
    vehicle traction will return. As it does,
    steer in the direction you want to go. Then put
    the transmission in drive or release the
    clutch, and accelerate slowly.

16
If you get Stuck
  • Dont spin your wheels. You will only dig in
    deeper.
  • Turn your wheels from side to side a few times to
    push snow out of the way.
  • Use a light touch on the gas pedal, to ease your
    car out.
  • Use a shovel to clear snow away from wheels and
    the cars underside.
  • Pour sand, kitty litter, gravel, or salt in the
    path of the wheels, to get traction.
  • Try rocking the vehicle. Shift from forward to
    reverse and back again. Each time youre in
    gear, give a light touch to the gas until the
    vehicle gets going.

17
If You Get Stranded
  • Do not leave your car unless you know exactly
    where you are, how far it is to possible help,
    and are certain you will improve your situation.
  • To attract attention, light two flares and place
    one at each end of the car a safe distance away.
    Hang a brightly colored cloth from your antenna.
    Keep your dome light on, it wont kill the
    battery.
  • If you are sure the car's exhaust pipe is not
    blocked, run the engine and heater for about 10
    minutes every hour or so depending upon the
    amount of gas in the tank.
  • To protect yourself from frostbite and
    hypothermia use the woolen items and blankets to
    keep warm.
  • Keep at least one window open slightly. Heavy
    snow and ice can seal a car shut.
  • Eat a hard candy to keep your mouth moist.

18
Snowplows
  • Drive with extra care and attention around
    snowplows
  • Dont crowd the plowgive them room to work. The
    plows are wide and can cross the centerline
  • or shoulder. Dont tailgate and try not to pass.
    If you must pass, take extreme caution and beware
  • of the snow cloud.
  • Snowplows travel below the posted speed limitbe
    patient.
  • A snowplow operators field of vision is
    restricted. You may see them but they may not see
    you.
  • Keep your distance and watch for sudden stops or
    turns.

19
  • Be extra wary of other motorists. They may not be
    driving as cautiously as you.

20
Winter Driving Slow down for wet, snowy, icy
conditions. Avoid quick braking or
acceleration. Find out about driving conditions
before you go. Everytime buckle up. Turn
signals, brake lights and windows need to be
clear of snow. You should never use cruise
control in winter weather conditions.
