Step Deck

A step deck trailer (also known as a drop deck) has two deck levels: a higher front section that sits over the tractor's rear wheels and a lower rear section that "drops" about 18-24 inches. This design allows the trailer to haul taller freight while keeping the total load height under the standard 13'6" legal maximum. The lower deck typically offers about 10 feet of vertical clearance versus 8.5 feet on a standard flatbed.

Step deck trailers are used for freight that is too tall for a standard flatbed but does not require a lowboy. Common step deck loads include tall machinery, industrial equipment, large vehicles, agricultural equipment, generators, and prefabricated structures. Total weight capacity is similar to a standard flatbed (approximately 43,000-48,000 pounds), but the distribution across the two deck levels requires careful load planning.

Step deck rates are premium — typically matching or exceeding standard flatbed rates at $3.25/mile or higher. The extra capability to handle taller freight opens up loads that fewer carriers can service, reducing competition and supporting higher rates. Many step deck carriers also accept standard flatbed loads when step deck freight is unavailable, giving them maximum flexibility.
