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.
A multi-trip permit may be issued for non-divisible loads up to 150,000 lbs. and is subject to higher fees. State law also authorizes the State Highway Patrol and local authorities to adopt rules to govern the movement of oversize and overweight vehicles.
