Stay visible:
Stop only where you can be seen from above.
Always look uphill before moving again.
Stop only at the edge of trails or next to stationary objects.
Slow down:
Limit your speed in busy areas.
Equalize your speed to the surrounding skiers.
Pay attention to others when making changes in direction or speed.
Give space:
Stand 5 meters from the others.
If you are within 5m of the others you have to slow down.
The faster you go, the more space you have to give to others.
