regional economy depends on expanding transportation capacity;
(b) Highway
transportation is the major mode for movement of people and goods in the

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; and

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.

system authorizing the operation of vehicles traveling between two (2) or more
participating jurisdictions at more adequate size and weight standards.

uniformity among participating jurisdictions in vehicle size and weight
standards on the basis of the objectives set forth in this agreement.

uniformity insofar as possible, of administrative procedures in the enforcement

for the encouragement and utilization of research which will facilitate the
