  1  2 the following new subsections:
  1  3    NEW SUBSECTION.  15A.  "Crane" means a machine for raising,
  1  4 shifting, and lowering heavy weights by means of a projecting
  1  5 swinging arm.
  1  6    NEW SUBSECTION.  63A.  "Retractable axle" means an axle
  1  7 designed with the capability of manipulation or adjustment of
  1  8 the weight on the axle by use of a manual device located on
  1  9 the vehicle that is not accessible to the operator of the
  1 10 vehicle during operation.  A vehicle or combination of
  1 11 vehicles operating with a retractable axle on a highway in
  1 12 this state shall comply with this paragraph on or after July
  1 13 1, 1999.
  1 14    Sec. 2.  Section 321.440, subsection 7, Code 1997, is
  1 15 amended to read as follows:
  1 16    7.  Been regrooved or recut below the original tread design
  1 17 depth, excepting special tires which have extra under tread
  1 18 rubber and are identified as such, or if a pneumatic tire was
  1 19 originally designed without grooves or tread, the safety
  1 20 standards therefor shall be established by the director.
  1 21    Sec. 3.  Section 321.440, Code 1997, is amended by adding
  1 22 the following new unnumbered paragraph after subsection 7:
  1 23    NEW UNNUMBERED PARAGRAPH.  A vehicle equipped with either
  1 24 solid rubber or pneumatic tires shall not be operated where
  1 25 the weight per inch of tire is greater than five hundred
  1 26 seventy-five pounds per inch based on the tire width rating,
  1 27 except on a steering axle, in which case six hundred pounds
  1 28 per square inch is permitted based on the tire width rating.
  1 29    Sec. 4.  Section 321.456, Code 1997, is amended to read as
  1 30 follows:
  1 31    321.456  HEIGHT OF VEHICLES – PERMITS – EXEMPTION.
  1 32    A vehicle unladen or with load shall not exceed a height of
  1 33 thirteen feet, six inches, except by permit as provided in
  1 34 this section.  However, a vehicle or combination of vehicles
  1 35 coupled together used exclusively for the transportation of
  2  1 passenger vehicles, light delivery trucks, panel delivery
  2  2 trucks, pickup trucks, or recreational vehicle chassis may
  2  3 operate without a permit provided that the height of the
  2  4 vehicle or vehicles coupled together does not exceed fourteen
  2  5 feet.  This section shall not be construed to require any
  2  6 railroad or public authorities to provide sufficient vertical
  2  7 clearance to permit the operation of such vehicle upon the
  2  8 highways of this state.  Any damage to highways, highway or
  2  9 railroad structures or underpasses caused by the height of any
  2 10 vehicle provided for by this section shall be borne by the
  2 11 operator or owner of the vehicle.  Vehicles unladen or with
  2 12 load exceeding a height of thirteen feet, six inches but not
  2 13 exceeding fourteen feet may be operated with a permit issued
  2 14 by the department or jurisdictional local authorities.  The
  2 15 permits shall be issued annually for a fee of twenty-five
  2 16 dollars and subject to rules adopted by the department.  The
  2 17 state or a political subdivision shall not be liable for
  2 18 damage to any vehicle or its cargo if changes in vertical
  2 19 clearance of a structure are made subsequent to the issuance
  2 20 of a permit during the term of the permit.
  2 21    Sec. 5.  Section 321.463, Code 1997, is amended to read as
  2 22 follows:
  2 23    321.463  MAXIMUM GROSS WEIGHT – EXCEPTIONS – PENALTIES.
  2 24    1.  An axle may be divided into two or more parts, except
  2 25 that all parts in the same vertical transverse plane shall be
  2 26 considered as one axle.
  2 27    2.  The gross weight on any one axle of a vehicle, or of a
  2 28 combination of vehicles, operated on the highways of this
  2 29 state, shall not exceed twenty thousand pounds on an axle
  2 30 equipped with pneumatic tires, and shall not exceed fourteen
  2 31 thousand pounds on an axle equipped with solid rubber tires.
  2 32 The gross weight on any tandem axle of a vehicle, or any
  2 33 combination of vehicles, shall not exceed thirty-four thousand
  2 34 pounds on an axle equipped with pneumatic tires.
  2 35    3.  Notwithstanding other provisions of this chapter to the
  3  1 contrary, indivisible loads operating under the permit
  3  2 requirements of sections 321E.7, 321E.8, and 321E.9 shall be
  3  3 allowed a maximum of twenty thousand pounds per axle.
  3  4    A group of two or more consecutive axles of any vehicle or
  3  5 combination of vehicles, shall not carry a load in pounds in
  3  6 excess of the overall gross weight determined by application
  3  7 of the following formula: W equals 500 (LN/N-1 + 12N + 36).  W
  3  8 equals the overall gross weight on any group of two or more
  3  9 consecutive axles to the nearest five hundred pounds, L equals
  3 10 the distance in feet, rounded to the nearest whole foot,
  3 11 between the extreme of any group of two or more consecutive
  3 12 axles, and N equals the number of axles in the group under
  3 13 consideration.  The following are exceptions to application of
  3 14 the formula:
  3 15    1.  Two consecutive sets of tandem axles may carry a gross
  3 16 load of thirty-four thousand pounds each providing the overall
  3 17 distance between the first and last axles of the consecutive
  3 18 sets of tandem axles is thirty-six feet or more.
  3 19    2.  On highways not part of the interstate system, a
  3 20 vehicle or combination of vehicles having:
  3 21    a.  Four axles where the extreme axles are eighteen feet
  3 22 apart may carry a gross load of fifty-three thousand pounds.
  3 23    b.  Five axles where the extreme axles are thirty-two feet
  3 24 apart may carry a gross load of sixty-seven thousand five
  3 25 hundred pounds.
  3 26    c.  Six or more axles where the extreme axles are forty-one
  3 27 feet apart may carry a gross load of seventy-eight thousand
  3 28 pounds.  
  3 29 For every foot of distance between extreme axles less than the
  3 30 above axle spacings, the overall gross weight of the vehicle
  3 31 or combination of vehicles shall be determined by deducting
  3 32 one thousand pounds from the gross loads specified in
  3 33 paragraphs "a", "b" and "c".  All measurements between extreme
  3 34 axles shall be rounded to the nearest whole foot.
  3 35    The maximum gross weight shall not exceed eighty thousand
  4  1 pounds.
  4  2    4.  a.  The maximum gross weight allowed to be carried on a
  4  3 vehicle or combination of vehicles on highways which are part
  4  4 of the interstate system is as follows:

  5 29 *Measured between the centers of the extreme axles of any
  5 30 group of axles and rounded to the nearest whole foot.  The
  5 31 above maximum gross weight table was calculated in accordance
  5 32 with the following formula:  W equals 500 (LN/N-1 + 12N + 36).
  5 33 W equals the overall gross weight on any group of two or more
  5 34 consecutive axles to the nearest five hundred pounds, L equals
  5 35 the distance in feet, rounded to the nearest whole foot,
  6  1 between the extreme of any group of two or more consecutive
  6  2 axles, and N equals the number of axles in the group under
  6  3 consideration.

  8  1    5.  The weight on any one axle, including a tandem axle, of
  8  2 a vehicle which is transporting livestock on highways not part
  8  3 of the interstate system may exceed the legal maximum weight
  8  4 given in this chapter providing that the gross weight on any
  8  5 particular group of axles on such vehicle does not exceed the

  9 22    b.  Fines for gross weight violations for vehicles or
  9 23 combinations of vehicles shall be assessed at one-half of the
  9 24 fine rate schedule for axle, tandem axle, and groups of axles
  9 25 weight violations.
  9 26    c.  Except as otherwise provided, the amount of the fine to
  9 27 be assessed shall be computed on the difference between the
  9 28 actual weight and the maximum legal weight specified in this
  9 29 section by applying the appropriate rate in the preceding
  9 30 schedule for the total amount of overload.
  9 31    d.  The schedule of fines may be assessed in addition to
  9 32 any other penalties provided for in this chapter.

 13 25                           EXPLANATION
 13 26    This bill does the following:
 13 27    1.  Code section 321.1 is amended to define a crane as a
 13 28 machine for raising, shifting, and lowering heavy weights by
 13 29 means of a projecting swinging arm.
 13 30    2.  Code section 321.440, regarding restrictions as to tire
 13 31 equipment, is amended to eliminate the requirement that the
 13 32 director of transportation adopt safety standards regarding
 13 33 pneumatic tires designed originally without grooves or tread.
 13 34 Code section 321.440 is also amended to prohibit vehicles from
 13 35 operating with tire weights per inch of tire that are greater
 14  1 than 575 pounds per inch on a nonsteering axle and 600 pounds
 14  2 per inch on a steering axle based on the tire width rating.
 14  3    3.  Code section 321.456, regarding height of vehicles, is
 14  4 amended to provide that vehicles used solely for the hauling
 14  5 of automobiles, light trucks, and recreational vehicle chassis
 14  6 are exempt from the need to get a permit if the load vehicle
 14  7 is 14 feet tall or under.
 14  8    Code section 321.463 is amended to state the maximum
 14  9 allowable vehicle weights for interstate and noninterstate
 14 10 highways in chart form.  The maximum weight is also increased
 14 11 to 96,000 pounds for vehicles on the interstate system.
 14 12    4.  Code section 321E.7, regarding load limits per axle of
 14 13 excessive size and weight vehicles, is amended to provide that
 14 14 cranes may temporarily be moved on streets, roads, or highways
 14 15 with gross weights per axle of up to 24,000 pounds.
 14 16    5.  Code section 321E.8, regarding annual permits, is
 14 17 amended to provide that vehicles with loads not more than 12
 14 18 feet five inches in width and not greater than 100 feet in
 14 19 length may be moved on highways specified by the permitting
 14 20 authority, provided that the vehicle owner or operator
 14 21 verifies to the permitting authority before moving the load
 14 22 that road conditions have not changed so as to prohibit the
 14 23 load from being moved.  The vehicle owner or operator is also
 14 24 liable for damages done to highways or highway structures from
 14 25 the load.  Section 321E.8 is also amended to prohibit these
 14 26 vehicles from traveling on the interstate highway system if
 14 27 the vehicle exceeds 80,000 pounds gross weight.
 14 28    6.  Code section 321E.9 is amended to provide that cranes
 14 29 exceeding the maximum gross axle weight allowed in section
 14 30 321.463 but not exceeding 24,000 pounds in axle weight may be
 14 31 moved under a single-trip permit in accordance with rules
 14 32 adopted by the department.
 14 33    7.  Code section 321E.9A is amended to provide that
 14 34 vehicles not more than 120 feet in length and 16 feet in width
 14 35 may be moved on highways designated by the permitting
 15  1 authority under a multi-trip permit provided that the total
 15  2 vehicle gross weight is not more than 156,000 pounds.
 15  3 Subsection 2 of that Code section is stricken.  Current size
 15  4 limitations are 11 feet in width, 120 feet in length, and 14
 15  5 feet four inches in height, and the weight limitation is
 15  6 determined under section 321E.7.
 15  7    8.  Code section 321E.14 is amended to increase the annual
 15  8 permit fee for vehicles with gross weights between 80,000 and
 15  9 136,000 pounds from $25 to $500.  The fee for all other annual
 15 10 permits remains at $25.  The fee for a multi-trip permit is
 15 11 increased from $100 to $200.
 15 12    The increase, to 96,000 pounds, in maximum gross weight for
 15 13 vehicles on the primary road system takes effect July 1, 1997,
 15 14 and takes effect for the urban and secondary road system on
 15 15 December 31, 1998.  Prior to that date, local authorities may
 15 16 approve routes of travel for 96,000-pound vehicles on urban
 15 17 and secondary roads.
