Overweight Load Permits

Does My Load Require Overweight Permits?

Permits must accompany loads heavier than the weight the department of transportation allows. Sometimes, a single pilot car or more must lead the way to help clear the roads. The Federal government allows 80,000lbs gross vehicle weight, 20,000lbs single axle weight, and 34,000lbs tandem axle weight. Overweight permits are acquired from the state’s department of transportation at a fee. Using a professional like Wide Load Shipping will save you the trouble of acquiring overweight permits, and the price is included in the final shipping estimate. 

Why Do You Need Overweight Permits?

By acquiring overweight permits, you notify the state’s department of transportation about your shipment. That means they recommend the best highway to avoid damaging roads and remove all the hindrances along the way. Your load must be accompanied by the overweight permit to show the highway patrols when stopped. Failure to have one will lead to fines. The Federal bridge weight formula is used to determine if commercial vehicles are complying with the rules. The formula used is W=500(LN/N-1 + 12N + 36). W is the overall gross weight of two or more consecutive axles to the nearest 500lbs, L is the distance between two extreme or more axles in feet, and N is the number of axles in the group.
