Before you cross Stevens Pass (US-2) or Blewett Pass (US-97) this winter, check the WSDOT pass report, carry chains, and know the signs: “Traction Tires Required” means approved traction tires on passenger vehicles, and “Chains Required” means chains unless you have 4WD/AWD, which must still carry chains. Studded tires are legal Nov. 1 through March 31.
What do the WSDOT pass signs mean?
Source: WSDOT Winter Driving Guide.
- Traction Tires Advised: oversize loads are prohibited. Drive for conditions.
- Traction Tires Required: all passenger vehicles need approved traction tires. Vehicles over 10,000 lbs GVWR, including some large pickups, SUVs and RVs, must chain up.
- Chains Required: all vehicles need chains except 4WD/AWD, which must still carry them. Violators face a $500 fine.
- Chains Required on All Vehicles: everyone chains up, including 4WD/AWD.
What counts as a traction tire in Washington?
At least 1/8 inch of tread and marked M+S, All Season, or the mountain/snowflake symbol. Any tire with chains installed counts. Studded tires do not meet a chain requirement. (WSDOT)
When can I run studded tires?
Nov. 1 through March 31 only, with no personal exceptions. WSDOT may extend the date if severe weather is forecast. (WSDOT)
Does the 10,000-pound rule apply to my truck or RV?
If your vehicle or combination is over 10,000 lbs GVWR, Washington requires you to carry chains Nov. 1 to April 1 on routes that include Stevens Pass (SR-2, MP 36–108) and Blewett Pass (US-97, MP 145–185). (WSP chain brochure: www.wsp.wa.gov/traveler/docs/cvd/chainbw.pdf; WAC 204-24-050) Check the GVWR on your door sticker.
What should Wenatchee drivers pack?
Chains that fit (practice installing them in your driveway first), a scraper, a blanket, water and snacks, a phone charger, a flashlight, and a small shovel. Leave Wenatchee with a full tank; services through Tumwater Canyon and over the passes can be far apart.
Is my car insurance ready for a winter slide-off?
Coverage depends on your policy, but ask yourself:
- Collision coverage: sliding into a guardrail or ditch is usually a collision claim. Without collision coverage, your own car’s damage may not be covered.
- Comprehensive: this typically handles falling rocks, trees or deer on US-2 and US-97.
- Roadside/towing: is it on your policy, and do you know the number?
- Liability limits: pass-traffic pileups can involve several vehicles.
We’ll go through your policy with you and shop the companies we work with if it makes sense.
