Your Wisconsin winter car kit.

Southeast Wisconsin winters bring dead batteries, slide-offs and long waits in the cold. A few items in the trunk make a stuck car much safer and easier to deal with.

The checklist

  • Ice scraper and snow brush
  • Small folding shovel
  • Bag of sand or cat litter for traction
  • Jumper cables or a charged jump pack
  • Warm blanket, hat and gloves
  • Phone charging cable and a charged power bank
  • Flashlight with fresh batteries
  • Water and a few snacks
  • Reflective triangles or flares
  • A basic first-aid kit

Before the first cold snap

Cold weather cuts a battery's power right when your engine needs the most to start. If your battery is three to five years old, have it tested before winter. Check your tire pressure too, since it drops as the temperature falls, and keep your gas tank at least half full.

If you get stuck in snow

  1. Don't spin your wheels. It digs the car in deeper.
  2. Clear snow away from the tires and spread sand or litter in front of the drive wheels.
  3. If you run the engine for heat, make sure the exhaust pipe is clear of snow. A blocked tailpipe can push carbon monoxide into the car.
  4. Run the engine for about 10 minutes each hour and crack a window slightly.
  5. If you can't get free, call for a winch-out.

If your car won't start

A click or a slow crank on a cold morning usually means the battery. Try a jump, or call for a jump start. Afterward, drive for at least 20 to 30 minutes and get the battery tested.

Questions

Quick answers.

What should I keep in my car in winter?

A scraper, shovel, sand or litter, jumper cables, a blanket, gloves, a phone charger, a flashlight, water and snacks, and reflective triangles.

Why does my car battery die in the cold?

Cold slows the chemical reaction inside the battery, so it delivers less power while the engine needs more to start.

Is it safe to run the engine while stuck in snow?

Only if the exhaust pipe is clear of snow. Run it for short periods and crack a window to avoid carbon monoxide buildup.
