Freight haulers are individuals or companies that transport goods from one place to another. They can include semi-trucks, vans, and SCOWS. Semi-trucks are large trucks with a trailer attached, usually used for long-distance hauling. Vans are smaller vehicles, typically used for local deliveries. SCOWS are flat-bottomed boats used to transport goods on rivers and other waterways. All of these vehicles are used to transport freight and goods from one place to another.
