1. (b) This sign is provided for use to warn traffic of a snowmobile crossing where conditions such as sight distance and number of snowmobiles crossing warrant such use. The provisions of subdivisions (b)-(d) of section 232.1 of the New York State Manual of Uniform Traffic Control Devices have general application in the consideration of the use of this sign.

   (c) The W86 sign is standard.

   The W86A or larger sign may be used where greater emphasis or visibility is required. The W86B sign may be used on highways, having no more than one moving lane of traffic in each direction, where approach speeds are low and where physical conditions make the use of the standard size sign impractical as a ground-mounted sign.

2. (d) Snowmobile is defined in section 21.05 of the Parks, Recreation and Historic Preservation Law, and Part 454 of the rules and regulations of the Office of Parks, Recreation and Historic Preservation, adopted September 1971.
3. (e) This sign may be used in advance of locations where snowmobiles cross the highway in a well defined path as part of a recognized trail crossing. The M57 (as specified in the New York State Manual of Uniform Traffic Control Devices) snowmobile route marker, supplemented with an M45 (as specified in the New York State Uniform Traffic Control Devices) white-on-brown directional marker arrow may be used at the trail crossing.
4. (f) The use of the snowmobile crossing sign shall be limited on a seasonal basis to between October 15th of one year and May 15th of the succeeding year.

(a) Design.
