Washington State Patrol Trooper Brian Moore urged drivers to “slow down, drive for these conditions” as he made his way through the snow-covered Blewett Pass to respond to spun-out semi trucks on December 19.

Snow blanketed the area, and several collisions and spin-outs were reported along I-90, including Snoqualmie Pass, where the Washington State Department of Transportation alerted a snow chain requirement. Credit: Trooper Brian Moore via Storyful
