Washington State Implements Winter Chain Requirements for Commercial Trucks

Washington state will mandate that commercial truck drivers carry chains on designated routes from November 1 through April 1, enforcing winter safety protocols across mountain passes and high-elevation corridors. The requirement applies to specific highways where snow and ice conditions create hazardous driving situations during the winter season. Carriers operating in the region must ensure compliance with the chain installation rules, which vary by route and weather conditions. The measure aims to prevent accidents and improve roadway safety during peak winter weather months. Drivers must carry appropriate chains and be prepared to install them when conditions warrant, typically when roads are snow-packed or icy. Failure to comply with the mandate can result in citations and penalties. The requirement affects major freight corridors throughout Washington and remains standard practice for winter operations in the Pacific Northwest.
