Yes, the Alaska Ski Safety Act includes the duties commonly understood between skiers – for instance, uphill skiers must yield to skiers below and merging skiers yield to skiers on the run.  

Skiers and snowboarders must stay within their skill level, stay aware of their surroundings, control their speed and direction, follow posted signs, ski only in designated areas, and avoid actions that could cause injury. If required signs were visible and readable at the start of the day, it is assumed that all skiers and snowboarders saw and understood them. 

Key rules include: 

1. Skiers and snowboarders must not pass others unless necessary to avoid contact and must yield to the person they are passing. 
2. Before starting from a stop or entering a trail, skiers and snowboarders must check for and avoid those already on the slope. 
3. Downhill skiers have the primary responsibility to avoid collisions with people or objects below them.
4. If a collision happens, the skier higher up the slope is usually considered responsible since they had the best chance to avoid it. 

Alaska law allows skiers and snowboarders to sue others for injuries, property damage, or death caused by another skier’s or snowboarder’s negligence.
