Each state sets its own legal axle weight limits, so it's essential to know the limit for each state on your route before setting out. The best source of information is the Department of Transportation website for each state.

In Alaska, there is no defined upper limit for gross weight, but single axle weight is limited to 20,000 lbs. In Hawaii, single axle weight is limited to 22,500 lbs, which is also the maximum weight for double axle.

In some states, like Montana, the gross weight limit is significantly higher, at 131,060 lbs. In contrast, South Carolina has a lower gross weight limit of 73,280 lbs.

Here's a breakdown of the maximum single axle weight limits by state:

A semi-truck's freight weight threshold is determined by subtracting the combined weight of the truck and trailer from the federal gross weight limit of 80,000 lbs. This means the weight of the tractor pulling each load, usually about 32,000 pounds, must be accounted for when calculating total gross weight.

The typical freight-weight thresholds for common trailer types are: 53-foot refrigerated trailers (43,000 to 45,000 pounds), 53-foot dry van trailers (43,000 to 46,000 pounds), and 53-foot flatbed trailers (45,000 to 48,000 pounds). Note that freight weight must be evenly distributed across the truck's axles.

A typical semi-truck weighs between 10,000 to 25,000 pounds, and when connected to an empty trailer, the combined weight can be approximately 35,000 pounds. However, these weights can vary depending on the make and model of the trailer and any additional equipment on the truck.

The weight capacity of a semi-truck is determined by several factors, including the weight of the tractor, the weight of the trailer, and the federal gross weight limit of 80,000 pounds.

The weight of the tractor typically ranges from 32,000 to 35,000 pounds, depending on the make and model.

To calculate the total gross weight, you need to subtract the combined weight of the truck and trailer from the federal gross weight limit.
