         1.  This chapter shall not be construed to prevent the owner of
      real property used by the public for purposes of vehicular travel by
      permission of the owner and not as matter of right from prohibiting
      such use, or from requiring other or different or additional
      conditions than those specified in this chapter, or otherwise
      regulating such use as may seem best to such owner.
         2. a.  The owner of real property upon which a manufactured
      home community or mobile home park is located may elect to have the
      vehicular traffic provisions of this chapter, or the ordinances,
      rules, or regulations of the local authority where the real property
      is located, apply to the real property and any persons located on the
      real property by granting authority to any peace officer to enforce
      the vehicular traffic provisions of this chapter, or the ordinances,
      rules, or regulations of the local authority as well as any
      regulations or conditions imposed on the real property pursuant to
      subsection 1.  An election made pursuant to this subsection shall not
      create a higher priority for the enforcement of traffic laws on real
      property upon which a manufactured or mobile home is located than
      exists for the enforcement of traffic laws on public property.
         b.  A written notice of election shall be filed with the
      designated officials of the local authority whose ordinances, rules,
      or regulations will govern the vehicular traffic.  The appropriate
      officials shall be the city clerk and chief of police of the city in
      which the real property is located and the county sheriff and the
      county recorder of the county in which the real property is located.
      The notice shall include the legal description of the real property,
      the street address, if any, and the date and time when the owner
      wishes the election to become effective.  The notice shall be signed
      by every titleholder of the real property and acknowledged by a
      notary public.
         c.  An election shall terminate fourteen days following the
      filing of a written notice of withdrawal with the designated
      officials of the local authority whose ordinances, rules, or
      regulations will govern.
         d.  For purposes of this subsection, "titleholder of real
      property" means the person or entity whose name appears on the
      documents of title filed in the official county records as the owner
      of the real property upon which a manufactured home community or
      mobile home park is located.
         3.  The titleholder of real property under subsection 2 may elect
      to waive the right to have the vehicular traffic provisions of this
      chapter, or the ordinances, rules, or regulations of the local
      authority where the real property is located, apply to the real
      property and any persons located on the real property, by recording a
      waiver with the county recorder of each county in which the property
      is located.  The waiver shall include the legal description of the
      real property and shall bind the titleholder of the real property and
      any successors in interest.  The waiver may only be rescinded if each
      law enforcement jurisdiction, in which the titleholder of real
      property wishes to obtain the benefit of this section, consents to
      the rescission of the waiver through adoption of a resolution.

         StartOfSec321.252  DEPARTMENT TO ADOPT SIGN MANUAL.
         The department shall adopt a manual and specifications for a
      uniform system of traffic-control devices consistent with the
      provisions of this chapter for use upon highways within this state.
      Such uniform system shall correlate with and so far as possible
      conform to the system then current as approved by the American
      association of state highway and transportation officials.
         The department shall include in its manual of traffic- control
      devices, specifications for a uniform system of highway signs for the
      purpose of guiding traffic to organized off-highway permanent camps,
      and camp areas, operated by recognized and established civic,
      religious, and nonprofit charitable organizations and to for- profit
      campgrounds and ski areas.  The department shall purchase, install,
      and maintain the signs upon the prepayment of the costs by the
      organization or owner.
         The department shall also establish criteria for guiding traffic
      on all fully controlled-access, divided, multilaned highways
      including interstate highways to each tourist attraction which is
      located within thirty miles of the highway and receives fifteen
      thousand or more visitors annually.  Nothing in this unnumbered
      paragraph shall be construed to prohibit the department from erecting
      signs to guide traffic on these highways to tourist attractions which
      are located more than thirty miles from the highway or which receive
      fewer than fifteen thousand visitors annually.
         The department shall establish, by rule, in cooperation with a
      tourist signing committee, the standards for tourist-oriented
      directional signs and shall annually review the list of attractions
      for which signing is in place.  The rules shall conform to national
      standards for tourist-oriented directional signs adopted under 23
      U.S.C. § 131(q) and to the manual of uniform traffic-control devices.
      The tourist signing committee shall be made up of the directors or
      their designees of the departments of economic development,
      agriculture and land stewardship, natural resources, cultural
      affairs, and transportation, the chairperson or the chairperson's
      designee of the Iowa travel council, and a member of the outdoor
      advertising association of Iowa.  The director or the director's
      designee of the department of economic development shall be the
      chairperson of the committee.  The department of transportation shall
      be responsible for calling and setting the date of the meetings of
      the committee which meetings shall be based upon the amount of
      activity relating to signs.  However, the committee shall meet at
      least once a month.  However, a tourist attraction is not subject to
      a minimum number of visitors annually to qualify for tourist-oriented
      directional signing.  The rules shall not be applicable to
      directional signs relating to historic sites on land owned or managed
      by state agencies, as provided in section 321.253A.  The rules shall
      include but are not limited to the following:
         1.  Criteria for eligibility for signing.
         2.  Criteria for limiting or excluding businesses, activities,
      services, and sites that maintain signs that do not conform to the
      requirements of chapter 306B, chapter 306C, division II, or other
      statutes or administrative rules regulating outdoor advertising.
         3.  Provisions for a fee schedule to cover the direct and indirect
      costs of sign manufacture, erection, and maintenance, and related
      administrative costs.
         4.  Provisions specifying maximum distances to eligible
      businesses, activities, services, and sites.  Tourist-oriented
      directional signs may be placed on highways within the maximum travel
      distance that have the greatest traffic count per day, if sufficient
      space is available.  If an adjacent landowner complains to the
      department about the placement of a tourist-oriented directional
      sign, the department shall attempt to reach an agreement with the
      landowner for relocating the sign.  If possible, the sign shall be
      relocated from the place of objection.  If the sign must be located
      on an objectionable place, it shall be located on the least
      objectionable place possible.
         5.  Provisions for trailblazing to facilities that are not on the
      crossroad.  Appropriate trailblazing shall be installed over the most
      desirable routes on lesser traveled primary highways, secondary
      roads, and city streets leading to the tourist attraction.
         6.  Criteria for determining when to permit advance signing.
         7.  Provisions specifying conditions under which the time of
      operation of a business, activity, service, or site is shown.
         8.  Provisions for masking or removing signs during off seasons
      for businesses, activities, services, and sites operated on a
      seasonal basis.  Faded signs shall be replaced and the commercial
      vendor charged for the cost of replacement based upon the fee
      schedule adopted.
         9.  Provisions specifying the maximum number of signs permitted
      per intersection.
         10.  Provisions for determining what businesses, activities,
      services, or sites are signed when there are more applicants than the
      maximum number of signs permitted.
         11.  Provisions for removing signs when businesses, activities,
      services, or sites cease to meet minimum requirements for
      participation and related costs.
         Local authorities shall adhere to the specifications for such
      signs as established by the department, and shall purchase, install,
      and maintain such signs in their respective jurisdictions upon
      prepayment by the organization of the cost of such purchase,
      installation, and maintenance.  The department shall include in its
      manual of traffic-control devices specifications for a uniform system
      of traffic-control devices in legally established school zones.

      traffic shall stop and after stopping may proceed cautiously through
      the intersection yielding to all vehicles not required to stop or
      yield which are within the intersection or approaching so closely as
      to constitute a hazard, but then may proceed.
         f.  A "flashing yellow" light means vehicular traffic
      shall proceed through the intersection or past such signal with
      caution.
         g.  A "don't walk" light is a pedestrian signal which
      means that pedestrian traffic facing the illuminated pedestrian
      signal shall not start to cross the roadway in the direction of the
