A dry van is a type of enclosed trailer commonly used in the transportation industry to haul various types of cargo. It's called a "dry" van because it's designed to keep the cargo protected from the elements, such as rain, snow, and wind. These trailers have a solid roof, walls, and a floor, which provides a secure and sheltered environment for goods during transit. Dry vans are versatile and can transport a wide range of products, from consumer goods and electronics to packaged foods and industrial materials.

In the USA, the standard dimensions for a dry van are typically:

Length: Approximately 53 feet (16.15 meters)
Width: About 8 feet (2.44 meters)
Height: Around 9 to 10 feet (2.74 to 3.05 meters)


It's important to note that these dimensions are standardized for highway transportation in the USA, but there can be variations and exceptions based on specific state regulations and road conditions. Additionally, there are shorter dry van options, such as 48 feet in length, which are also commonly used.

Dry vans are popular because they offer several advantages, including protection of cargo from weather and theft, ease of loading and unloading through rear doors, and the ability to transport goods over long distances. They are a common sight on highways, delivering products to distribution centers, retail stores, factories, and other destinations as part of the broader logistics and supply chain network.
