First Rule
Perhaps the most important guideline of the Code is the first one:
Always stay in control, and be able to stop or avoid other people or objects.
Having another skier crash into you makes for a bad day and can result in serious injury. Just as you wouldn't want an out of control skier or snowboarder to run into you, you should maintain the same level of control.
Right of Way
The next three steps in the Code have to do with right of way on the slopes. They are:
People ahead of you have the right of way. It is your responsibility to avoid them.
You must not stop where you obstruct a trail, or are not visible from above.
Whenever starting downhill or merging into a trail, look uphill and yield to others.
By following these three steps, skiers and snowboarders can significantly reduce or eliminate collisions. Always be aware when you head down that the skiers and snowboarders ahead of you have the right of way, and the fact that you are skiing faster doesn't eliminate that. If you stop, don't do so blindly; look around and make sure that you can be seen by skiers coming from above.
The Tinal Three
The last three aspects of the Code have to do with equipment, both personal and resort.
Always use devices to help prevent runaway equipment.
Observe all posted signs and warnings. Keep off closed trails and out of closed areas.
Prior to using any lift, you must have the knowledge and ability to load, ride and unload safely.
Runaway skis can be a significant hazard, so make sure your skis are equipped with leashes or brakes. Make sure you know how to ride the lift, because if you can't, it can significantly delay other skiers while you get on or off.
Finally, obey all posted trail closures and signs. Don't duck the ropes to ski untracked lines. The ski patrol puts closures up for a reason. In addition to the heavy monetary penalty you could pay if caught, you could trigger an avalanche or get caught on obstructions lurking under the snow and hurt yourself.
