Maine winters call for extra skill. On snow and ice, the keys are slower speeds, gentler stops and turns, and much more following distance. Know how to steer out of a skid and how to survive being stuck.

Before bad weather hits:

  • Get a tune-up so the car runs well and gets the best fuel efficiency
  • Make sure your tires are in good condition, or put on snow tires
  • Have a mechanic check antifreeze, water hoses, exhaust, battery charge and brakes
  • Use oil of sufficient weight for winter and keep battery terminals clean

30 seconds

Usually enough time to let your engine idle before driving in winter

Handbook p. 115 ↗

Know the rule

A cold engine warms faster driven than idling. In extreme cold, drive at slower speeds for a few miles. Test the brakes occasionally at low speed to judge how slippery the road is, and never slam on the brakes.

Handbook p. 115 ↗

Steering out of a skid:

  • Stay off the brake; braking hard locks the wheels and worsens the skid
  • Turn the wheel in the direction you want the car to go
  • As the car straightens, turn the wheel back so you don't overcorrect
  • Keep correcting left and right until you fully recover
Handbook p. 115 ↗

Know the rule

If you can't control the car on a slippery surface, look for something to stop you: get a wheel onto dry pavement or the shoulder, or slowly edge into a snowbank or bushes.

Handbook p. 116 ↗

Know the rule

When stopping on ice or snow, pump the brakes very gently and let up at the first hint of slipping. Don't release the clutch or shift out of drive until nearly stopped. With anti-lock brakes, just press firmly.

3 to 12 times

How much more distance it takes to stop on snow or ice than on dry pavement

Handbook p. 116 ↗

Know the rule

Slow down for hills and curves, turn gradually, and keep windshield, wipers, defroster, headlights and washer fluid in working order.

Handbook p. 116 ↗

Know the rule

If you get stuck, don't spin your wheels. Keep them straight, shovel snow away, and use traction mats, sand or cat litter. If you still can't get out, rock the car between reverse and drive.

Handbook p. 116 ↗

If you must wait for help:

  • Stay with your car; most deaths occur when people leave it, get lost and freeze
  • Put a red flag on the antenna or door handle; set flares front and rear if you have them
  • Wrap everyone in blankets or warm clothing
  • Run the engine and heater until warm, then shut it off; repeat when cold
  • Crack the windows and keep the exhaust pipe clear of snow to avoid carbon monoxide
  • Stay active; don't let anyone go to sleep
Handbook p. 116 ↗

Winter supplies to carry:

  • Shovel
  • Flares and a red flag for your antenna
  • Ice scraper
  • Jumper cables
  • Bag of sand
  • Warm clothing and footwear
Handbook p. 116 ↗

Know the rule

Drivers of vehicles under 10,000 pounds must take reasonable measures to prevent snow or ice from falling off their vehicle while driving.

Handbook p. 116 ↗

Put it into practice

Your rear end slides right on an icy curve. Get off the brake, steer where you want the front to go, and as the car straightens, bring the wheel back so you don't swing into a new skid.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

How much farther can it take to stop on snow or ice compared to dry pavement?
  1. About twice as far
  2. 3 to 12 times as far
  3. 1.5 to 2 times as far
  4. 20 to 30 times as far

Answer: 3 to 12 times as far

On snow or ice it takes three to twelve times as much distance to stop as on dry pavement.

Handbook p. 116 ↗
What is the first rule for steering out of a skid?
  1. Stay off the brake
  2. Shift into neutral
  3. Accelerate sharply
  4. Brake hard immediately

Answer: Stay off the brake

Stay off the brake when skidding; hard braking will lock the wheels and worsen the skid.

Handbook p. 115 ↗
If you get stuck in snow, what should you avoid doing with your wheels?
  1. Spinning them
  2. Shoveling around them
  3. Turning them straight
  4. Adding sand for traction

Answer: Spinning them

If you get stuck, don't spin your wheels; keep them straight and add traction material instead.

Handbook p. 116 ↗
If you must wait in your car for help during a winter storm, what should you do periodically?
  1. Leave the car to find help
  2. Run the engine and heater, then shut it off, repeating as needed
  3. Turn off the car completely until help arrives
  4. Keep windows fully sealed at all times

Answer: Run the engine and heater, then shut it off, repeating as needed

Run the engine and heater until the car is warm, then shut it off, and repeat when you feel cold again.

Handbook p. 116 ↗
About how long is enough time to idle your engine before driving in cold weather?
  1. About 30 seconds
  2. About 5 minutes
  3. About 10 minutes
  4. About 1 minute

Answer: About 30 seconds

Thirty seconds is usually enough time to allow your engine to idle before driving.

Handbook p. 115 ↗
Most deaths in winter breakdown situations happen to people who stay in their car waiting for help.
  1. True
  2. False

Answer: False

False. The handbook says to stay with your car, because most deaths occur when people leave the car, get lost, and freeze to death.
