Section 25.19. Operation by youthful operators

1. Age of operation. No
  person under eighteen years of age shall operate a snowmobile except  as
  provided  for  in  this  subdivision.  (a)  No  person  under the age of
  fourteen years shall operate a snowmobile  except  upon  land  owned  or
  leased  by  his  or her parent or guardian. Leased lands as used in this
  section shall not include lands leased by an organization of which  said
  operator or his or her parent or guardian is a member.
    (b) A person ten years of age or older but less than fourteen years of
  age  who  holds  a  valid  snowmobile  safety  certificate issued by the
  commissioner  may  operate  a  snowmobile  on  any  lands   upon   which
  snowmobiling  is  allowed if accompanied by a person over eighteen years
  of age. For the purpose of this section, "accompanied" shall mean within
  five hundred feet of the person over eighteen years of age.
    (c) A person fourteen years of age or older  but  less  than  eighteen
  years  of  age,  who  either holds a valid snowmobile safety certificate
  issued by the commissioner or is accompanied by a person  over  eighteen
  years  of  age,  may operate a snowmobile in the same manner as a person
  over eighteen years of age.
    2. Exhibition of certificate. The failure of  a  person  specified  in
  subdivision  one of this section to hold a snowmobile safety certificate
  issued  by  the  commissioner  to  exhibit  such  upon  demand  to   any
  magistrate, peace officer, acting pursuant to his or her special duties,
  police  officer,  or  other  person  having  authority  to  enforce  the
  provisions of this article, shall  not  be  an  offense,  but  shall  be
  presumptive  evidence  that  such  person  is  not  the  holder  of such
  certificate.
    3. Authorization. No owner of a snowmobile shall authorize  or  permit
  the operation of his or her snowmobile within the state by any person in
  violation of the provisions of this section.
