Winter is when a dead battery or a slide off the road turns serious. Ready.gov keeps a short list that fits in any trunk.

What to pack

Ready.gov lists:

  • Jumper cables (or a portable jump starter)
  • Flares or a reflective triangle
  • Ice scraper
  • Car phone charger
  • Blanket
  • Map
  • Cat litter or sand for traction

Before winter, have a mechanic check

Antifreeze, battery and ignition, brakes, exhaust, filters, heater and defroster, lights, oil, thermostat, and wipers and washer fluid. Ready.gov also suggests winter tires with enough tread. Check yours with our tire guide.

On the road

  • Keep the tank full so the fuel line does not freeze.
  • Turn off cruise control on slippery roads.
  • If the car gets hard to control, pull over and set the parking brake.
  • If a power line falls on the car, stay inside.
  • Do not drive through floodwater. Six inches can stall a car, and a foot floats many.
