Section 71O. No skier shall embark or disembark upon a recreational tramway except at a designated location and during designated hours of operation, throw or expel any object from any recreational tramway while riding thereon, act in any manner while riding on a recreational tramway that may interfere with its proper or safe operation, engage in any type of conduct which may injure any person, or place any object in the uphill ski track which may cause another to fall while traveling uphill on a ski lift, or cross the uphill track of a recreational tramway except at designated locations. A skier shall maintain control of his speed and course at all times, and shall stay clear of any snow-grooming equipment, any vehicle, towers, poles, or other equipment.

A skier who boards a recreational tramway shall be presumed to have sufficient abilities to use the same, and shall follow any written or oral instruction given regarding its use and no skier shall embark on a recreational tramway without authority of the operator. A skier skiing down hill shall have the duty to avoid any collision with any other skier, person or object on the hill below him, and, except as otherwise provided in this chapter, the responsibility for collisions by any skier with any other skier or person shall be solely that of the skier or person involved and not that of the operator, and the responsibility for the collision with any obstruction, man-made or otherwise, shall be solely that of the skier and not that of the operator, provided that such obstruction is properly marked pursuant to the regulations promulgated by the board. No skier shall ski on any ski slope or trail or portion thereof which has been designated closed, nor ski on other than an identified trail, slope or ski area. Any person skiing on other than an open slope or trail within the ski area shall be responsible for any injuries resulting from his action. A skier shall be presumed to know the range of his own ability to ski on any slope, trail or area. A skier shall be presumed to know of the existence of certain unavoidable risks inherent in the sport of skiing, which shall include, but not be limited to, variations in terrain, surface or subsurface snow, ice conditions or bare spots, and shall assume the risk of injury or loss caused by such inherent risks. A skier shall, prior to his entrance onto the slope or trail, other than one designated for cross-country skiing, or embarking on any recreational tramway, have attached on his skis, a strap or other device for the purpose of restraining or preventing a runaway ski. A ski area operator who finds a person in violation of this section, may issue an oral warning to that individual. A person who fails to heed the warning issued by such ski area operator shall forfeit his recreational tramway ticket and recreational tramway use privileges and may be refused issuance of another such ticket to the recreational tramway.
