Before you leave:
Load your car with winter travel gear: tire chains, ice scraper/snow brush, jumper cables and road flares.
Keep a basic winter survival kit in your vehicle: flashlight, batteries, blanket, snacks, water, gloves, boots, first-aid kit.
Check tires and make sure chains fit before driving in snowy weather
Check oil, brakes, headlights, wipers etc.
Studded tires are allowed in Washington from Nov. 1 to Mar. 31.
Keep your gas tank full: WSDOT recommends not falling below half a tank during winter trips.
WSDOT updates their Twitter (@WSDOT) with road conditions. Their app also shows current road conditions.
On the road:
Watch for signs or check the app to find out when traction tires are advised, when chains are advised for trucks and when chains are required for all vehicles.
Drive slower, leave extra space between vehicles to give yourself more time to stop
Do not use cruise control
Leave extra room between your vehicle and the vehicle in front of you
Slow down when approaching intersections, offramps, bridges or shady spots
If you find yourself behind a snowplow, slow down and give the plow extra room
If you find yourself stranded, be safe, stay in your car, put on your flashers, call for help and wait until it arrives.
