Washington ski law primarily protects ski resorts from liability, requiring them to follow only a few key safety measures, mainly related to signage. Resorts must use clear, bold signs to mark closed trails, restricted areas, and lift closures, and they must ensure snowmaking and grooming equipment is properly marked. Vehicles like snowmobiles must have visible identification, and ski lifts must display signs indicating difficulty levels and instructions for unfamiliar users. While suing a ski resort for injuries is challenging, it is possible if the resort was negligent. Each case depends on its unique facts, so consulting a legal expert promptly after an injury is crucial.
