(2)
(a) No person may operate a snowmobile on any highway except in the following manner or as otherwise authorized by law:
1. Directly across any roadway having fewer than 5 lanes, but only after stopping and yielding the right-of-way to all vehicles approaching on the roadway. Crossings under this subdivision may be made only at a place where no obstruction prevents a quick and safe crossing. For purposes of this subdivision, “obstruction" includes but is not limited to impairment of view and dangerous roadway condition.
1m. Directly across a roadway having 5 lanes, in the manner specified in subd. 1., but only if the department of transportation authorizes such a crossing.
2. On any roadway which is not normally maintained for other vehicular traffic by the removal of snow.
3. On the roadway of highways to cross a bridge, culvert or railroad right-of-way unless posted by the maintaining authority, but shall yield the right-of-way to all vehicular traffic.

5. On highways which have been designated as routes and which are required to be marked.
6. On a portion of the roadway or shoulder of a highway for a purpose of residential access or for the purpose of access from lodging if the town, city or village, within which that portion of the highway lies, enacts an ordinance under s. 350.18 (3) for that portion of the highway.
(b) Snowmobiles may be operated adjacent to a roadway with due regard to safety in the following manner:
1. Along U.S. numbered highways, state and county highways at a distance of 10 or more feet from the roadway. Travel upon the median of a divided highway is prohibited except to cross.
2. Along town highways outside of the roadway.
3. During daylight hours travel may be in either direction regardless of the flow of vehicular traffic.
4. At night travel shall conform to the direction of vehicular traffic in the nearest lane unless the snowmobile is operated on a designated and marked snowmobile trail.
5. Whenever it is impracticable to gain immediate access to an area adjacent to a highway, other than a freeway, where a snowmobile is to be operated, the snowmobile may be operated adjacent and parallel to the roadway for the purpose of gaining access to and from the area of operation. Loading or unloading of the snowmobile shall be accomplished with due regard to safety at the nearest practical point to the area of operation.
(2m) No person may operate a snowmobile on or adjacent to a roadway in excess of the applicable roadway speed limit established under s. 346.57 or 349.11 unless the person is operating the snowmobile as part of a special event authorized under s. 350.04.
