On four-lane divided highways there are no pilot car requirements for movements not exceeding 16 feet in width.
Load Exceeding 16 feet in overall width:
One pilot car is required to precede each movement at a distance of 300 to 700 feet and one pilot car is required to follow each movement at a distance of 300 to 700 feet on two-lane highways.
One pilot car is required to follow each movement at a distance of 300 to 700 feet on four-lane divided highways.
Exceeding 18 feet in overall width:
The movement will be subject to Highway Patrol escort if deemed necessary by the regional commander(s).

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.ANNUAL PERMIT
