Key Specifications of Semi-trailers
Semi-trailers come in various dimensions and weight limits, each designed to meet specific transportation needs. Understanding these two specifications are crucial when selecting the right trailer for your business: dimensions and weight limits, and payload capacity.
Dimensions and weight limits of semi-trailers:
In the United States, semi-trailers typically adhere to standard dimensions to ensure compatibility with highways and loading docks. The maximum legal length for a semi-trailer is 53 feet, with a maximum width of 8.5 feet. The height limit is usually about 13.5 feet. These limits ensure compliance with transportation regulations and safe passage.
Weight limits vary depending on the type of trailer and the number of axles. A standard tandem axle trailer can typically carry up to 40,000 pounds of cargo. However, individual states may have specific weight restrictions, making it essential to consult local regulations to ensure compliance.

The payload capacity refers to the maximum weight of cargo a semi-trailer can carry. This capacity is determined by subtracting the trailer's tare weight from its gross vehicle weight rating (GVWR). For example, if a trailer has a GVWR of 80,000 pounds and a tare weight of 20,000 pounds, its payload capacity would be 60,000 pounds.
Considering the payload capacity when selecting a semi-trailer is critical to avoid overloading, which can lead to safety hazards, fines, and potential damage to the trailer or goods being transported.
A semi-trailer is a vehicle without its own engine that you connect to a tractor via a kingpin. An important feature is that the semi-trailer carries part of the weight of the load and is partly supported by the tractor. This makes the combination stable and maneuverable, especially for heavy and long transport.

Standard semi-trailer
A standard semi-trailer is one of the most common semi-trailers on the roads. They are also called tautliners in the industry.
