As snow blankets the Cascades and winter driving conditions worsen, the Washington State Patrol (WSP) is cracking down on drivers who fail to comply with traction tire and tire chain requirements. On November 20, 2024, WSP’s District 6 Commercial Motor Vehicle (CMV) troopers conducted a chain enforcement patrol on Snoqualmie Pass, a critical transportation route known for its treacherous winter road conditions. Their focus: ensuring that all vehicles, from passenger cars to commercial trucks, meet the state’s winter driving safety standards.

Traction Tire Laws: What You Need to Know

Snoqualmie Pass is a gateway for commerce and recreation, but its snow-covered roads can pose significant risks. To mitigate these dangers, Washington law requires vehicles to use approved traction tires or tire chains when conditions demand it. Alerts issued by the Washington State Department of Transportation (WSDOT) outline when and where these requirements apply. Key points to remember include:

  • Traction Tires: These must be marked with the Mountain/Snowflake symbol or meet WSDOT standards for winter driving.
  • Tire Chains: Commercial vehicles and certain passenger vehicles are required to carry and install chains during severe conditions unless equipped with alternative traction devices.
  • Penalties: Drivers failing to comply with chain requirements may face fines of up to $500, even if the violation doesn’t result in an accident.

This emphasis on enforcement highlights the importance of traction tires for preventing accidents, reducing road closures, and ensuring safe travel for all.

Prepare for Safe Winter Travel

To avoid fines and keep your family safe this winter, follow these tips:

  1. Check Your Tires: Confirm they are rated for winter conditions and have adequate tread depth.
  2. Carry Chains: Always have tire chains in your vehicle, especially when traveling over mountain passes.
  3. Monitor WSDOT Alerts: Stay updated on road conditions and chain requirements at WSDOT’s website.
  4. Practice Installation: Learn how to install chains before encountering snow-covered roads.
