Section R17-6-411 - Maximum Permitted Weights

A. Except as provided under R17-6-212, an applicant requesting an envelope or special permit under this Chapter for transporting a nonreducible overweight or oversize and overweight vehicle, combination of vehicles, or vehicle and load combination shall use the formulas and computations provided under Illustration 3 and Tables 3.01 through 3.09 to determine the maximum weights allowed on any combination of axles spaced within a maximum distance of 18 feet between the front and rear axle of each axle group.

B. The formulas and computations provided under Illustration 3, and Tables 3.01 through 3.09, are an expansion of the federal bridge formula provided under A.R.S. § 28-1100 for use by the Department when issuing an overweight or oversize and overweight envelope or special permit for movement of a non-reducible vehicle or load under this Chapter.

C. The axle group weights provided under Illustration 3, and Tables 3.01 through 3.09, represent the maximum weights allowed on any combination of axles spaced within a distance of up to 18 feet between the front and rear axle of any given group. The values in Table 3.01 line "A" are an expression of the formula W = 1.5 x 700 (L + 40) for L = 3' 5" to 18' 0", where L is the distance between the centers of the front and rear axles of an axle group. The values in line "B" and in the remaining Tables are calculated by applying the percentages provided in the Table footnotes to increase the allowable weights based on wider axle width and an increased number of tires. Measured axle widths are rounded down to the nearest 3" increment when determining the appropriate Table to use.
