        321G.9  OPERATION ON ROADWAYS AND HIGHWAYS.         A person shall not operate a snowmobile upon roadways or highways,      as defined in section 321.1, except as provided in this chapter.         1.  A snowmobile shall not be operated at any time within the      right-of-way of any interstate highway or freeway within this state      except when using an underpass located on an interstate highway or      freeway if all of the following apply:         a.  The underpass has been abandoned and is no longer being      used by motor vehicles or trains.         b.  Use of the underpass is the only alternative to the use of      a traveled roadway.         c.  Notwithstanding the provisions of chapter 321, use of the      underpass does not conflict with any rules or regulations adopted by      a federal governmental entity or this state or a political      subdivision of this state.         2.  A snowmobile may make a direct crossing of a street or highway      provided all of the following occur:         a.  The crossing is made at an angle of approximately ninety      degrees to the direction of the highway and at a place where no      obstruction prevents a quick and safe crossing.         b.  The snowmobile is brought to a complete stop before      crossing the shoulder or main traveled way of the highway.         c.  The driver yields the right-of-way to all oncoming traffic      which constitutes an immediate hazard.         d.  In crossing a divided highway, the crossing is made only      at an intersection of such highway with another public street or      highway.         3.  A snowmobile shall not be operated on public highways under      any of the following conditions:         a.  On the roadway portion of a highway and adjacent shoulder,      or at least five feet on either side of the roadway, except as      provided in subsection 4.         b.  On limited access highways and approaches.         c.  For racing any moving object.         d.  Abreast with one or more other snowmobiles on a city      highway.         4.  A registered snowmobile may be operated under the following      conditions:         a.  Upon city highways which have not been plowed during the      snow season or on such highways as designated by the governing body      of a municipality.         b.  On that portion of county roadways that have not been      plowed during the snow season or not maintained or utilized for the      operation of conventional two-wheel drive motor vehicles.         c.  On highways in an emergency during the period of time when      and at locations where snow upon the roadway renders travel by      conventional motor vehicles impractical.         d.  On the roadways of that portion of county highways      designated by the county board of supervisors for such use during a      specified period.  The county board of supervisors shall evaluate the      traffic conditions on all county highways and designate roadways on      which snowmobiles may be operated for the specified period without      unduly interfering with or constituting an undue hazard to      conventional motor vehicle traffic.  Signs warning of the operation      of snowmobiles on the roadway shall be placed and maintained on the      portions of highway thus designated during the period specified for      the operation.         e.  On the roadway or shoulder when necessary to cross a      bridge or culvert, or avoid an obstruction which makes it impossible      to travel on the portion of the highway not intended for motor      vehicles, if the snowmobile is brought to a complete stop before      entering onto the roadway or shoulder and the driver yields the      right-of-way to any approaching vehicle on the roadway.         f.  Snowmobiles shall not be operated on all-terrain vehicle      trails except where designated by the controlling authority and the      primary all-terrain vehicle trail sponsor.         5.  The headlight and taillight shall be lighted during the      operation on a public highway at any time from sunset to sunrise, and      at such other times when conditions such as fog, snow, sleet or rain      provide insufficient lighting to render clearly discernible persons      and vehicles at a distance of five hundred feet ahead.         6. a.  A snowmobile shall not be operated on or across a      public highway by a person under sixteen years of age who does not      have in the person's possession a safety certificate issued to the      person pursuant to this chapter.         b.  A person twelve to fifteen years of age and possessing a      valid safety certificate must be under the direct supervision of a      parent, guardian, or another adult authorized by the parent or      guardian, who is experienced in snowmobile operation, and who      possesses a valid driver's license as defined in section 321.1, or a      safety certificate issued under this chapter.         7.  A snowmobile shall not be operated within the right-of-way of      a primary highway between the hours of sunset and sunrise except on      the right-hand side of the right-of-way and in the same direction as      the motor vehicular traffic on the nearest lane of traveled portion      of the right-of-way.
