(c) Notwithstanding any other provisions of this title, the overall gross weight on a group of 2 or more consecutive axles may not exceed an amount produced by application of the following formula:
( | LN | ) | ||||||
W = 500 | ( | + | 12N | + | 36 | ) | ||
( | N - 1 | ) |
where “W” = overall gross weight on any group of 2 or more consecutive axles to the nearest 500 pounds, “L” = distance in feet measured horizontally between the vertical centerlines of the extreme of any group of 2 or more consecutive axles, and “N” = number of axles in group under consideration, except that 2 consecutive sets of tandem axles may carry a gross load of 34,000 pounds each providing the overall distance between the first and last axles of such consecutive sets of tandem axles is 36 feet or more; provided, that such overall gross weight may not exceed eighty thousand (80,000) pounds, including any enforcement or statutory tolerances.
(d) The following table indicates the permissible overall gross weights based upon the above formula:
Distance in feet between the extremes of any group of 2 or more consecutive axles | 2 axles | 3 axles | 4 axles | 5 axles | 6 axles | 7 axles |
