assigned to a snowmobile shall be displayed on the vehicle at all times
in such manner as the commissioner may, by regulation, prescribe. No
number other than the number assigned to a snowmobile by the
commissioner or the identification number of the registration in another

operated in special events, approved by the commissioner of parks and
recreation, may be temporarily displayed for the duration of the race.

2. Dealer demonstrator registration numbers shall conform to the
requirements set forth in subdivision one of this section with the
exception that the numbers assigned may be printed upon or attached to a
removable plaque or plaques to be temporarily but firmly affixed to the
snowmobile being demonstrated or tested.

3. Numbers issued to dealers and manufacturers for the purpose of
demonstration or testing shall be used exclusively for these purposes
and no other use is permitted.
