Winter Driving
Why not keep this information in your glove compartment?
Winter driving
Winter
travel by automobile can be serious business. Be prepared. If you do a
lot of winter driving in isolated regions, you might consider having a
citizens' band radio.
*9-1-1 is a free call to police and ambulance on your cellular phone.
Heed the warnings
Local weather offices of Environment
Canada issue warnings of impending blizzards, heavy snow, freezing
rain or drizzle, cold waves and winds.
Know the hazards
Blizzard |
The most perilous of winter storms, combining falling, blowing,
drifting snow, winds of 40 kilometres per hour or more, visibility
less than 1 kilometre, temperatures less than -10°C; duration:
six hours or more. |
Heavy snow |
10 centimetres or more in 12 hours, or 15 centimetres or more in
24 hours. Even less in temperate climates. |
Freezing rain or drizzle |
An ice storm coating roads, trees, overhead wires, etc with ice.
|
Cold wave |
A rapid fall in temperature in a short period, requiring greater-than-normal
protective measures. |
Winds |
The cause of blizzard conditions, drifting, reduced visibility and
wind-chill effects. |
Black ice |
Where the road ahead looks like black and shiny asphalt. Shaded
areas of the road, bridges and overpasses freeze sooner in cold weather,
long after the sun has come out. |
Tune up your car
Winter weather presents the greatest challenge to your car and its engine.
Prepare for winter by getting a complete check-up in the fall.
Check the following systems
Mechanical system |
Your tune-up should include battery, belts, hoses, radiator,
coolant/antifreeze, oil, lights, brakes, exhaust system, heater/defroster,
wipers and ignition system. |
Battery |
Cold-weather starts require a fully charged battery.
Recharge or replace weak batteries. Check fluid levels, battery posts,
voltage regulator, alternator or generator. |
Ignition system |
Damaged ignition wires, a cracked distributor cap or
worn spark plugs can make starting difficult or may cause a sudden
breakdown. |
Lights |
Regularly check that all lights are functioning properly
and that headlights are properly aimed. |
Brakes |
To ensure even braking, brakes should be
checked and, if needed, serviced. Pulling, a taut pedal, or unusual
squealing or grinding may indicate a need for repair. |
Tires |
Traction is the key to good movement, turning and stopping on wet
surfaces. Check the tires and tire pressure at least once a month
when the tires are cold. Remember that tire air pressure decreases
in colder weather. Tires should be properly inflated to the maximum
pressure amount shown in the owner's manual or on the door frame.
Do not exceed pressure shown on the tire sidewall. Check your spare
tire regularly.
Identical tires on all four wheels will improve vehicle handling.
Mixing tires with different tread patterns, internal construction
and size degrades the stability of the vehicle and should be avoided.
Tires marked with the pictograph of a peaked mountain with a snowflake
meet specific snow-traction performance requirements and have been
designed specifically for use in severe snow conditions. |
Exhaust system |
Have the exhaust system fully checked for leaks that
could send carbon monoxide into your vehicle. |
Heating and cooling system |
Check your radiator and hoses for cracks and leaks.
Make sure the radiator cap, water pump and thermostat work properly.
Test the strength of the anti-freeze and test the functioning of the
heater and defroster. |
Windshield wipers and washer |
Make sure wipers are in good condition and fill up on
winter washer fluid. Blades that streak should be replaced. Make sure
there is enough windshield washer fluid in the reservoir and that
it is rated in the -40°C temperature range. Carry an extra jug
in the vehicle. |
Prepare the driver
If you must drive in bad weather, think caution, plan ahead and make sure
you have enough fuel. Try to keep the fuel tank at least half-full.
Be
alert, well-rested and sober behind the wheel. Check mirrors and environment
controls before you start. Don't forget to wear your seat belt and to
ensure all children are correctly positioned in appropriate child car
seats and booster seats. Children aged 12 and under should ride properly
buckled up in the back seat.
See and be seen. Clear all snow from the hood, roof, windows and lights.
Clear all windows of fog. If visibility becomes poor, find a place to
safely pull off the road as soon as possible. It's best to stop at a rest
area or exit the roadway and go to a protected area.
If the roadside is your only option, pull off the road as far as you
can. Other drivers frequently strike vehicles parked at the side of the
road. In reduced visibility, you should make sure your emergency flashers
are on to alert other drivers.
Check weather and travel conditions before heading out. Give yourself
extra time for travel and, if weather is bad, wait for conditions to improve.
Plan your route and let someone know which way you'll be travelling, your
destination and expected arrival time, especially when driving long distances.
If you don't turn up after a reasonable delay, people will know where
to search for you. If the going gets tough, turn back or seek refuge.
- Try to keep to the main roads and drive with caution, measuring your
speed to road and weather conditions.
- Avoid passing another vehicle, if possible, when weather and road
conditions are bad.
- Wear warm clothes that do not restrict movement.
It's a good idea to take a cellphone with you. It can be very valuable,
especially in an emergency or if you need help. But don't talk and drive.
Drivers should not use a cellphone while the vehicle is in motion. Let
a passenger call for you or pull over to a safe spot to place a call for
assistance.
Winter car survival kit
The Canadian Automobile Association recommends the following items be kept
in the trunk of your car.
- shovel
- sand or cat litter
- traction mats
- tow chain
- compass
![winter car survival kit](/web/20061123122912im_/http://ww3.psepc-sppcc.gc.ca/info_pro/self_help_ad/general/images/car_kit.jpg)
- cloth or roll of paper towels
- warning light or road flares
- extra clothing and footwear
- emergency food pack
- booster cables
- ice scraper and brush
- matches and a "survival" candle in a deep can (to warm hands,
heat a drink or use as an emergency light)
- fire extinguisher
- extra windshield washer fluid
- fuel line antifreeze
The following items should be kept in the cab of your car.
- road maps
- flashlight
- first aid kit
- blanket (special "survival" blankets are best)
If you get trapped in a storm or snow-bank, don't panic!
Avoid overexertion and exposure. Shovelling and bitter cold can kill.
Stay in your car. You won't get lost and you'll have shelter.
- Keep fresh air in your car. Open a window on the side sheltered from
the wind.
![dead end](/web/20061123122912im_/http://ww3.psepc-sppcc.gc.ca/info_pro/self_help_ad/general/images/deadend_e.jpg)
- Run your motor sparingly. Beware of exhaust fumes and the possibility
of carbon monoxide. Ensure the tailpipe is not blocked by snow.
- Use the candle for heat, instead of the car's heater, if possible.
- Set out a warning light or flares. Put on the dome light. (Overuse
of headlights may run your battery down.)
- Exercise your limbs vigorously. Keep moving and don't fall asleep.
Keep watch for traffic or searchers.
- Wear a hat, as you can lose up to 60 percent of your body heat through
your head.
Keep control of your vehicle to avoid collisions
Winter collisions can occur when your vehicle skids. Remember that not
all vehicles respond in the same way to icy, slippery roads. You must
know how to handle your vehicle and how it responds in various weather
conditions. Consult your owner's manual and familiarize yourself with
your vehicle's braking system and tire traction. You may want to consider
taking a driver education course that teaches emergency driving techniques.
Skids can best be avoided by driving for conditions, slowing down, allowing
extra time to get to your destination and anticipating lane changes, turns
and curves. Also recommended: slow down in advance, make smooth, precise
movements of the steering wheel, be sensitive to how your vehicle is steering.
Even careful and experienced drivers experience skids. Don't panic! Learn
to handle skids and remember that, sometimes, the vehicle will skid a
second and even third time after the initial skid.
Rear-wheel skids
If the rear wheels lose traction, use these steps to regain control after
a skid:
- Take your foot off the brake if the rear wheels skid due to hard or
panic braking.
- Ease off the gas pedal if the rear wheels lose traction due to hard
acceleration (rear-wheel drive).
![rear-wheel skids](/web/20061123122912im_/http://ww3.psepc-sppcc.gc.ca/info_pro/self_help_ad/general/images/rear_skid.jpg)
- Shift to neutral.
- Look down the road in the direction you want the front of the car
to go; be sensitive to the feel of the car and how it is responding
to your steering.
- To regain control of the vehicle, steer gently in the direction of
the skid of the rear of the vehicle. Just before the skid ends, bring
the front wheels straight. Sometimes the vehicle will skid in the opposite
direction, so you may have to repeat the movement until the vehicle
stabilizes.
- Once the vehicle is straight, return to a driving gear and accelerate
gently so that engine speed matches road speed.
Front-wheel skids
Front-wheel skids are caused by hard braking or acceleration and by entering
a curve too fast. When the front wheels lose traction, you lose steering
ability. The best way to regain control if the front wheels skid is:
- If the front wheels skid from hard braking, release the brake. If
the wheels spin from loss of traction due to acceleration, ease off
on the accelerator (front-wheel drive).
![front-wheel skids](/web/20061123122912im_/http://ww3.psepc-sppcc.gc.ca/info_pro/self_help_ad/general/images/front_skid.jpg)
- Shift to neutral.
- If the front wheels have been turned prior to the loss of traction,
don't move the steering wheel. Since the wheels are skidding sideways,
a certain amount of braking force will be extended.
- Wait for the front wheels to grip the road again. When traction returns,
you'll regain steering control.
- Return to a driving gear and gently steer in the direction you want
to travel. Gently accelerate until engine speed matches road speed.
Four-wheel skids
Sometimes all four wheels lose traction -- generally at high speeds under
adverse conditions. The most effective way to get your vehicle back under
control when all four wheels skid is:
- Remove your foot from the brake or accelerator.
- Shift into neutral.
![four-wheel skids](/web/20061123122912im_/http://ww3.psepc-sppcc.gc.ca/info_pro/self_help_ad/general/images/4wheel_skid.jpg)
- Look and steer in the direction you want the front of the car to go.
- Wait for the wheels to grip the road again. As soon as the wheels
regain traction, you will travel in the direction you want to go.
- Return to a driving gear and maintain a safe speed. NOTE: Avoid using
overdrive on slippery surfaces.
Braking
To survive on the road in winter, proper braking is essential.
Stopping on a slippery surface requires more space, so increase your
following distance. Focus your attention as far ahead as possible.
The best way to stop on a slippery surface is to use threshold or controlled
braking and shift to neutral. If you don't have anti-lock brakes, the
best way to use threshold or controlled braking is to keep the heel of
your foot on the floor and use your toes to apply firm, steady pressure
on the brake pedal. Stop just short of locking the wheels.
If
your heel leaves the floor, the ball of your foot pushes the pedal. The
wheels lock because you're controlling the brake with your thigh muscles
which are incapable of finer control.
Under the stress of trying to stop quickly, drivers almost inevitably
over-react and lock the wheels. If this happens, release brake pressure
one or two degrees, then immediately reapply it with slightly less pressure.
Anti-lock brakes are designed to prevent wheels from locking and allow
continued steering control during panic braking. Sensors located at wheels
detect lock-up. The anti-lock system relieves enough pressure to allow
the wheel to turn, maintaining steering control.
Do not remove your foot from the brake or pump the pedal. If you apply
too much brake pressure and the wheels lock momentarily, you might feel
the brake pedal pulse back against your foot. Pumping the pedal works
against the system by providing false information.
