34     carry a greater weight than the manufacturer's rating.
35          (2) (a) An individual may not operate or move a vehicle on any highway in the state
36     with:
37          (i) a gross weight in excess of 10,500 pounds on one wheel;

47     
W = 500 {LN/(N-1) + 12N+36}

48          (i) W = overall gross weight on any group of two or more consecutive axles to the
49     nearest 500 pounds.
50          (ii) L = distance in feet between the extreme of any group of two or more consecutive
51     axles. When the distance in feet includes a fraction of a foot of one inch or more the next

54          (b) Two consecutive sets of tandem axles may carry a gross weight of 34,000 pounds

58     natural gas or powered primarily by means of electric battery power may exceed any vehicle
