where W equals maximum weight in pounds carried on any group of two or more axles; L equals distance in feet between the extremes of any group of two or more consecutive axles; and N equals number of axles in the group under consideration except that two consecutive sets of tandem axles may carry a gross load of 34,000 lb. each, providing the overall distance between the first and last axles of the consecutive sets of tandem axles is at least 36 feet.

Gross Vehicle Weight on highways other than the Interstate System

The maximum gross vehicle weight on state highways: 105,500 lb. unless otherwise posted.

On all other highways the maximum gross vehicle weight is: 80,000 lb. unless designated for more, not to exceed 105,500 lb.

The weight per inch of tire width shall not exceed 550 pounds.

The gross weight on a tandem axle may not exceed 34,000 pounds.

The gross weight of three or more axles in a grouping may not exceed 48,000 pounds on highways other than the interstate system.

Using the Ton Mile Fee Schedule you can determine the price per mile for the overweight fine. These permits can range from 500$ to well over 10,000$ so pay attention to the weights. If in doubt about how the weights should be distributed, click here (Insert a call to action for our axle spacings calculator) 

This chart will allow you to calculate your overweight costs per trip. There are 2 possible ways you can be charged. Gross Vehicle Weight and Axle Group Weight. You can be charged per group and also the overall GVW, and these charges must be combined to create an accurate permit charge.
