MOTOR VEHICLES - GROSS AXLE WEIGHT - Amends existing law relating to
allowable gross loads of motor vehicles to clarify that the manufacturer's
gross axle weight rating and gross tire weight rating shall not be less
than the actual loading of the axle or the tire, and to delete the
requirement that the pressure regulator valve which controls operation of
a variable load suspension axle shall be set and sealed.

That Section 49-1001, Idaho Code, be, and the same is hereby 11 amended to read as follows: 12 49-1001. ALLOWABLE GROSS LOADS. The gross load imposed on the highway by 13 any vehicle or combination of vehicles shall not exceed the limits in this 14 section. The maximum single axle gross weight shall be twenty thousand 15 (20,000) pounds, the maximum single wheel gross weight shall be ten thousand 16 (10,000) pounds and the maximum gross vehicle or combination weight shall be 17 one hundred five thousand five hundred (105,500) pounds, provided that maximum 18 gross vehicle or combination weight on United States federal interstate and 19 defense highways of this state shall not exceed eighty thousand (80,000) 20 pounds, except as permitted under the provisions of section 49-1004, Idaho 21 Code. 22 (1) The total gross weight imposed on the highway by any group of consec- 23 utive axles shall be determined by the following formula: 24 W=500((LN/N-1)+12N+36) 25 Where W is the maximum weight in pounds (to the nearest 500 pounds) car- 26 ried on any group of two (2) or more consecutive axles. L is the distance in 27 feet between the extremes of any group of two (2) or more consecutive axles, 28 and N is the number of axles under consideration. 29 The formula is modified as illustrated in the following table: 30 Distance in feet 31 between the 32 extremes of any Maximum load in pounds carried on any group of 33 group of 2 or 2 or more consecutive axles 34 more consecutive 35 axles 2 axles 3 axles 4 axles 5 axles 6 axles 7 axles 8 axles 9 axles 36 4 34,000 37 5 34,000 WHEN NO ALLOWABLE WEIGHT IS 38 6 34,000 LISTED FOR ANY AXLE SPACING, 39 7 34,000 APPLY THE ALLOWABLE WEIGHT AS 40 8 34,000 LISTED IN THE FIRST COLUMN TO 41 8+ 38,000 42,000 THE LEFT 42 9 39,000 42,500 43 10 40,000 43,500 2 1 11 44,000 2 12 45,000 50,000 3 13 45,500 50,500 4 14 46,500 51,500 5 15 47,000 52,000 6 16 48,000 52,500 58,000 7 17 48,500 53,500 58,500 8 18 49,500 54,000 59,000 9 19 50,000 54,500 60,000 10 20 51,000 55,500 60,500 66,000 11 21 51,500 56,000 61,000 66,500 12 22 52,500 56,500 61,500 67,000 13 23 53,000 57,500 62,500 68,000 14 24 54,000 58,000 63,000 68,500 74,000 15 25 54,500 58,500 63,500 69,000 74,500 16 26 55,500 59,500 64,000 69,500 75,000 17 27 56,000 60,000 65,000 70,000 75,500 18 28 57,000 60,500 65,500 71,000 76,500 82,000 19 29 57,500 61,500 66,000 71,500 77,000 82,500 20 30 58,500 62,000 66,500 72,000 77,500 83,000 21 31 59,000 62,500 67,500 72,500 78,000 83,500 22 32 60,000 63,500 68,000 73,000 78,500 84,500 90,000 23 33 64,000 68,500 74,000 79,000 85,000 90,500 24 34 64,500 69,000 74,500 80,000 85,500 91,000 25 35 65,500 70,000 75,000 80,500 86,000 91,500 26 36 66,000 70,500 75,500 81,000 86,500 92,000 27 37 66,500 71,000 76,000 81,500 87,000 93,000 28 38 67,500 71,500 77,000 82,000 87,500 93,500 29 39 68,000 72,500 77,500 82,500 88,500 94,000 30 40 68,500 73,000 78,000 83,500 89,000 94,500 31 41 69,500 73,500 78,500 84,000 89,500 95,000 32 42 70,000 74,000 79,000 84,500 90,000 95,500 33 43 70,500 75,000 80,000 85,000 90,500 96,000 34 44 71,500 75,500 80,500 85,500 91,000 96,500 35 45 72,000 76,000 81,000 86,000 91,500 97,500 36 46 72,500 76,500 81,500 87,000 92,500 98,000 37 47 73,500 77,500 82,000 87,500 93,000 98,500 38 48 74,000 78,000 83,000 88,000 93,500 99,000 39 49 74,500 78,500 83,500 88,500 94,000 99,500 40 50 75,500 79,000 84,000 89,000 94,500 100,000 41 51 76,000 80,000 84,500 89,500 95,000 100,500 42 52 76,500 80,500 85,000 90,500 95,500 101,000 43 53 77,500 81,000 86,000 91,000 96,500 102,000 44 54 78,000 81,500 86,500 91,500 97,000 102,500 45 55 78,500 82,500 87,000 92,000 97,500 103,000 46 56 79,500 83,000 87,500 92,500 98,000 103,500 47 57 80,000 83,500 88,000 93,000 98,500 104,000 48 58 84,000 89,000 94,000 99,000 104,500 49 59 85,000 89,500 94,500 99,500 105,000 50 60 85,500 90,000 95,000 100,500 105,500 51 61 86,000 90,500 95,500 101,000 52 62 87,000 91,000 96,000 101,500 53 63 87,500 92,000 96,500 102,000 54 64 88,000 92,500 97,500 102,500 55 65 88,500 93,000 98,000 103,000 3 1 66 89,500 93,500 98,500 103,500 2 67 90,000 94,000 99,000 104,500 3 68 90,500 95,000 99,500 105,000 4 69 91,000 95,500 100,000 105,500 5 70 92,000 96,000 101,000 6 71 92,500 96,500 101,500 7 72 93,000 97,000 102,000 8 73 93,500 98,000 102,500 9 74 94,500 98,500 103,000 10 75 95,000 99,000 103,500 11 76 95,500 99,500 104,500 12 77 96,000 100,000 105,000 13 78 97,000 101,000 105,500 14 79 97,500 101,500 15 80 98,000 102,000 16 81 98,500 102,500 17 82 99,000 103,000 18 83 100,000 104,000 19 84 104,500 20 85 105,000 21 86 or more 105,500 22 (a) A public highway agency may limit the application of the weights 23 authorized in this section as to certain highways within its jurisdiction 24 which it determines have limited structural capacity of pavements, 25 bridges, or other appurtenances. In designating such highways, it may 26 specify a minimum wheelbase for combinations to be operated thereon. It 27 may also designate specific highways or portions on which operation of a 28 combination of vehicles with seven (7), eight (8) or nine (9) axle vehi- 29 cles will be subject to specified lesser allowable gross weights. 30 (b) Notwithstanding the figures shown in the table in this subsection 31 (1), two (2) consecutive sets of tandem axles may carry a gross load of 32 thirty-four thousand (34,000) pounds each, providing the overall distance 33 between the first and last axles of such consecutive sets of tandem axles 34 is thirty-six (36) feet or more. 35 (2) The weight limitations set forth in the table in subsection (1) of 36 this section shall not apply to any vehicle, or combination of vehicles when a 37 greater allowed weight in pounds would be permitted such vehicles under the 38 table provided in this subsection, except that with regard to transportation 39 on the United States federal interstate and defense highways of this state, 40 the following table of allowable weights shall apply only to vehicles engaged 41 in the transportation of logs, pulp wood, stull, rough lumber, poles or pil- 42 ing; or to any such vehicle engaged in the transportation of ores, concen- 43 trates, sand and gravel and aggregates thereof, in bulk; or to any such vehi- 44 cle engaged in the transportation of agricultural commodities, including live- 45 stock: 46 Distance in feet between Allowed Load in Pounds 47 the extremes of any group Vehicles with Vehicles with 48 of 2ofor more consecutive Three or Four Five or more 49 axles axles axles 50 3 through 12 37,800 37,800 51 13 56,470 56,470 52 14 57,940 57,940 53 15 59,400 59,400 54 16 60,610 60,610 55 17 61,820 61,820 4 1 18 63,140 63,140 2 19 64,350 64,350 3 20 65,450 65,450 4 21 66,000 66,330 5 22 66,000 67,250 6 23 66,000 67,880 7 24 66,000 68,510 8 25 66,000 69,150 9 26 66,000 69,770 10 27 66,000 70,400 11 28 66,000 70,950 12 29 66,000 71,500 13 30 66,000 72,050 14 31 72,600 15 32 73,150 16 33 73,700 17 34 74,250 18 35 74,800 19 36 75,350 20 37 75,900 21 38 76,450 22 39 77,000 23 40 77,550 24 41 78,100 25 42 78,650 26 43 and over 79,000 27 The weight allowances provided in this subsection do not apply if the total 28 gross weight of a vehicle or combination of vehicles is intended to exceed 29 seventy-nine thousand (79,000) pounds as declared by the operator. When the 30 provisions of this subsection are applicable to a vehicle or combination of 31 vehicles, it shall be a violation of the provisions of this subsection if that 32 vehicle or combination of vehicles exceeds the weights specified in this 33 table. 34 (3) In determining the gross weight of a vehicle or the gross weight of 35 any two (2) or more consecutive axles under subsection (1) or (2) or (9) of 36 this section, the total gross weight of the vehicle or combination of vehicles 37 or the gross weight of any two (2) or more consecutive axles shall be the sum 38 of the axle weights. 39 For the purposes of this chapter the gross weight of a vehicle or the 40 gross weight of any two (2) or more consecutive axles may be determined by 41 accumulatively adding the separate weights of individual axles and tandem 42 axles or groups of axles to determine gross weight. The results of any weigh- 43 ing at a temporary or permanent port of entry and the records relating to the 44 calibration and accuracy of any scale at a temporary or permanent port of 45 entry shall be admissible in any proceeding in this state. In order to prove a 46 violation of the provisions of this section the state must show that: 47 (a) The sum of the axle weights exceeds what is allowable under the pro- 48 visions of subsection (1) or (2) or (9) of this section; 49 (b) The scale involved in the weighing was at the time of weighing cali- 50 brated in conformity with and met the accuracy requirements of the stan- 51 dards for the enforcement of traffic and highway laws as set forth in the 52 latest edition of handbook 44 of the national institute of standards and 53 technology; 54 (c) Weights of individual axles or axles within a commonly suspended 55 group of axles supported by a mechanical system designed to distribute 5 1 equal wheel loads to individual axles in the group were utilized only to 2 determine gross weights of that group of axles, and that any further eval- 3 uation of gross weights of combinations of axles considered only the accu- 4 mulated gross weight of each such commonly suspended group of axles. 5 (4) In applying the weight limitations imposed in this section, a vehicle 6 or combination of vehicles must comply exclusively with the weight limitations 7 in either subsection (1) or (2) or (9) of this section. 8 (5) In applying the weight limitations imposed in this section, the dis- 9 tance between axles shall be measured to the nearest even foot. When a frac- 10 tion is exactly one-half (1/2) foot the next larger whole number shall be 11 used. 12 (6) The limitations imposed in this section are in addition and supple- 13 mental to all other laws imposing limitations upon the size and weight of 14 vehicles. Further, single axles within groups of axles are subject to the pro- 15 visions and limitations of this chapter. Single axles within groups of axles 16 may be weighed and evaluated separately, or single axles may be prequalified 17 in accordance with rules or ordinances established by the board or other pub- 18 lic road jurisdiction, if any of the following conditions exist regarding the 19 single axle within a group of axles: 20 (a) A suspension system common to all axles in the group of axles does 21 not exist. 22 (b) One (1) or more axles in the group of axles is equipped with separate 23 variable load suspension controls to regulate the weight carried by indi- 24 vidual axles. 25 (c) One (1) or more axles in a group of axles is equipped with more or 26 fewer tires than other axles in the group of axles. 27 (d) All tires in the group of axles are not the same size as determined 28 by the manufacturer's sidewall rating. 29 (7) Notwithstanding the other provisions of this chapter, no vehicle, 30 motor vehicle, trailer and/or semitrailer, or combination thereof, may be 31 operated on the public highways of the state under loads which would result in 32 the withholding of funds by operation of controlling federal law as provided 33 in the Federal Aid Highway Act of 1956, as amended. 34 (8) Except as provided herein, no vehicle or combination of vehicles may 35 proceed past the place of weighing at temporary or permanent ports of entry or 36 checking stations when: the weight of a single axle exceeds the maximum limi- 37 tations set forth herein by two thousand (2,000) pounds or more; the weight of 38 a combination of axles, or gross vehicle weight exceeds the maximum allowable 39 weight as set forth herein by seven percent (7%) or more. Vehicles or combina- 40 tions of vehicles which exceed the weight limitations set forth herein shall 41 be required to be brought into compliance with applicable weight limitations 42 contained within this subsection at the place of weighing prior to continuing, 43 except those vehicles or combinations of vehicles which are transporting loads 44 which, in the determination of the board or other proper authorities in charge 45 of or having jurisdiction over a highway, are deemed unsafe or impractical to 46 bring into compliance at the place of weighing, and except those vehicles 47 which do not exceed fifteen percent (15%) over maximum axle and axle group 48 weights set forth in this section. Vehicles or combinations of vehicles trans- 49 porting loads in this latter category shall obtain a travel authorization to 50 the nearest place of safe unloading, load adjustment or other means of 51 legalization. 52 (a) Neither the state of Idaho or its employees, nor any authority and 53 its employees in charge of or having jurisdiction over a highway, shall be 54 held liable for personal injury or property damage resulting from the 55 requirements of section 49-1001(8), Idaho Code. 6 1 (b) The fee for a travel authorization as set forth above shall be fifty 2 dollars ($50.00) and shall be on a form prescribed by the board or other 3 proper authorities, and shall not be construed as contributing to a reduc- 4 tion in the penalties prescribed in section 49-1013, Idaho Code. 5 (c) The board or other proper authorities in charge of or having juris- 6 diction over a highway shall adopt and enforce administrative rules as may 7 be necessary to carry out the provisions of this section. 8 (9) For vehicles on all highways except the United States federal inter- 9 state and defense highways of this state, the following table shall apply: 10 Distance in feet between Allowed Load in Pounds 11 the extremes of any group Vehicles with Vehicles with 12 of 2ofor more consecutive Three or Four Five or more 13 axles axles axles 14 3 through 12 37,800 37,800 15 13 56,470 56,470 16 14 57,940 57,940 17 15 59,400 59,400 18 16 60,610 60,610 19 17 61,820 61,820 20 18 63,140 63,140 21 19 64,350 64,350 22 20 65,450 65,450 23 21 66,000 66,330 24 22 66,000 67,250 25 23 66,000 67,880 26 24 66,000 68,510 27 25 66,000 69,150 28 26 66,000 69,770 29 27 66,000 70,400 30 28 66,000 70,950 31 29 66,000 71,500 32 30 66,000 72,050 33 31 72,600 34 32 73,150 35 33 73,700 36 34 74,250 37 35 74,800 38 36 75,350 39 37 75,900 40 38 76,450 41 39 77,000 42 40 77,550 43 41 78,100 44 42 78,650 45 43 and over 80,000 46 The weight allowances provided in this subsection do not apply if the total 47 gross weight of a vehicle or combination of vehicles is intended to exceed 48 eighty thousand (80,000) pounds as declared by the operator.

STATEMENT OF PURPOSE
RS 07875
This legislation would amend Title 49, Section 49-1001,
Idaho Code, to amend those provisions governing vehicles
equipped with variable load suspension (VLS) axle(s).
The proposed changes would delete the requirement that VLS
axles be rated at not less than 9,000 pounds gross axle
weight but require that no VLS axle be loaded in excess of
the manufacturer's gross axle weight rating. This proposal
also deletes the requirement that the pressure regulator
valve of such VLS axle-equipped vehicles be set and sealed
by the owner.
FISCAL NOTE
None.
