Historic snowcoach means a Bombardier snowcoach manufactured in 1983 or earlier. Any other snowcoach is considered a non-historic snowcoach.
Oversnow route means that portion of the unplowed roadway located between the road shoulders and designated by snow poles or other poles, ropes, fencing, or signs erected to regulate oversnow activity. Oversnow routes include pullouts or parking areas that are groomed or marked similarly to roadways and are adjacent to designated oversnow routes. An oversnow route may also be distinguished by the interior boundaries of the berm created by the packing and grooming of the unplowed roadway. The only motorized vehicles permitted on oversnow routes are oversnow vehicles.

Snowmobile means a self-propelled vehicle intended for travel on snow, with a curb weight of not more than 1,000 pounds (450 kg), driven by a track or tracks in contact with the snow, and which may be steered by a ski or skis in contact with the snow.
Snowplane means a self-propelled vehicle intended for oversnow travel and driven by an air-displacing propeller.
(3) May I operate a snowmobile in Yellowstone National Park?
(i) You may operate a snowmobile in Yellowstone National Park in compliance with use limits, guiding requirements, operating hours and dates, equipment, and operating conditions established under this section. The Superintendent may establish additional operating conditions and must provide notice of those conditions in accordance with § 1.7(a) of this chapter or in the Federal Register.
(ii) The authority to operate a snowmobile in Yellowstone National Park established in paragraph (l)(3)(i) of this section is in effect only through the winter season of 2012-2013.

Such critical emissions-related components may only be replaced with the original equipment manufacturer (OEM) component, where possible. Where OEM parts are not available, aftermarket parts may be used if they are certified not to worsen emission and sound characteristics.
(iv) Modifying or disabling a snowcoach's original pollution control equipment is prohibited except for maintenance purposes.

(iv) The guiding requirements described in this paragraph (l)(9) do not apply to snowmobiles being operated on the Cave Falls Road.
(10) Are there limits established for the number of snowmobiles and snowcoaches permitted to operate in the park each day? The number of snowmobiles and snowcoaches allowed to operate in the park each day is limited to a certain number per entrance or location. The limits are listed in the following table:
Park entrance/location Commercially guidedsnowmobiles Commercially guided snowcoaches
* Commercially guided snowmobile tours originating at the North Entrance and Old Faithful are currently provided solely by Xanterra Parks and Resorts. Because this concessioner is the sole provider at both of these areas, this regulation allows reallocation of snowmobiles between the North Entrance and Old Faithful as necessary, so long as the total daily number of snowmobiles originating from the two locations does not exceed 24. For example, the concessioner could operate 6 snowmobiles at Old Faithful and 18 at the North Entrance if visitor demand warranted it. This will allow the concessioner to respond to changing visitor demand for commercially guided snowmobile tours, thus enhancing the availability of visitor services in Yellowstone.
** These snowmobiles operate on an approximately 1-mile segment of road within the park where the use is incidental to other snowmobiling activities in the Caribou-Targhee National Forest. These snowmobiles do not need to be guided or to meet NPS air and sound emissions requirements.
(i) North Entrance * 12 13
(ii) West Entrance 160 34
(iii) South Entrance 114 13
(iv) East Entrance 20 2
(v) Old Faithful * 12 16
(vi) Cave Falls ** 50 0
(11) When may I operate my snowmobile or snowcoach? The Superintendent will determine operating hours and dates. Except for emergency situations, any changes to operating hours will be made on an annual basis, and the public will be notified of those changes through one or more of the methods listed in § 1.7(a) of this chapter.
(12) What other conditions apply to the operation of oversnow vehicles?
(i) The following are prohibited:
(A) Idling an oversnow vehicle for more than 5 minutes at any one time.

Oversnow vehicles may not be stopped in a hazardous location or where the view might be obscured, or operated so slowly as to interfere with the normal flow of traffic.
(B) Oversnow vehicle drivers must possess a valid motor vehicle driver's license. A learner's permit does not satisfy this requirement. The license must be carried by the driver at all times.

(D) Snowmobiles must be properly registered and display a valid registration from a state or province in the United States or Canada, respectively.
