The participating jurisdictions find that:
(a) The expanding regional economy depends on expanding transportation capacity.
(b) Highway transportation is the major mode for movement of people and goods in the western states.
(c) Uniform application in the west of more adequate vehicle size and weight standards will result in a reduction of pollution, congestion, fuel consumption and related transportation costs which are necessary to permit increased productivity.
(d) A number of western states, already having adopted substantially the 1964 bureau of public roads recommended vehicle size and weight standards, still find current federal limits more restrictive.
(e) The participating jurisdictions are most capable of developing vehicle size and weight standards most appropriate for the regional economy and transportation requirements, consistent with and in recognition of principles of highway safety.

The purposes of this agreement are to:
(a) Adhere to the principle that each participating jurisdiction should have the freedom to develop vehicle size and weight standards that it determines most appropriate to its economy and highway system.

(c) Promote uniformity among participating jurisdictions in vehicle size and weight standards on the basis of the objectives set forth in this agreement.
(d) Secure uniformity as far as possible of administrative procedures in the enforcement of recommended vehicle size and weight standards.
(e) Provide means for the encouragement and utilization of research which will facilitate the achievement of the purposes of this section, with due regard for the findings set forth in section 1 of this article.

Objectives of the Participating Jurisdictions
Section 1. Objectives.
The participating jurisdictions declare that:
(a) It is the objective of the participating jurisdictions to obtain more efficient and more economical transportation by motor vehicles between and among the participating jurisdictions by encouraging the adoption of standards that will, as minimums, allow the operation on all state highways, except those determined through engineering evaluation to be inadequate, with a single axle weight of twenty thousand pounds, a tandem axle weight of thirty-four thousand pounds, and a gross vehicle or combination weight of that resulting from application of the formula:
W = 500 ((LN/N - 1) + 12N + 36)
Where W = maximum weight in pounds carried on any group of two or more axles computed to the nearest five hundred pounds.
L = distance in feet between the extremes of any group of two or more consecutive axles.
N = number of axles in the group under consideration.
(b) It is the objective of the participating jurisdictions that the operation of a vehicle or combination of vehicles in interstate commerce according to the provisions of subsection (a) of this section be authorized under special permit authority by each participating jurisdiction for vehicle combinations in excess of a statutory weight of eighty thousand pounds or statutory lengths, or both.
(c) It is the objective of the participating jurisdictions to facilitate and expedite the operation of any vehicle or combination of vehicles between and among the participating jurisdictions under the provisions of subsection (a) or (b) of this section and to that end the participating jurisdictions agree, through their designated representatives, to meet and cooperate in the consideration of vehicle size and weight related matters including the development of: uniform enforcement procedures; additional vehicle size and weight standards; operational standards; agreements or compacts to facilitate regional application and administration of vehicle size and weight standards; uniform permit procedures; uniform application forms; rules and regulations for the operation of vehicles, including equipment requirements, driver qualifications and operating practices and such other matters as may be pertinent.
(d) The cooperating committee may recommend that the participating jurisdictions jointly secure congressional approval of this agreement, specifically of the vehicle size and weight standards set forth in subsection (a) of this section.
(e) It is the further objective of the participating jurisdictions to:
(i) Establish transportation laws and regulations to meet regional needs and to promote an efficient, safe and compatible transportation network.
