Load-to-Truck Ratio

The load-to-truck ratio is a key market indicator that measures the balance between freight demand (available loads) and trucking capacity (available trucks). A ratio of 3:1 means there are three loads posted for every available truck, indicating a tight market where shippers may struggle to find capacity and rates are likely rising. A ratio of 1:1 or lower indicates an oversupplied market with abundant truck capacity and downward pressure on rates.

In the refrigerated freight market, the load-to-truck ratio is consistently higher than the dry van market because there are fewer reefer-equipped trucks and the freight is more concentrated in specific lanes and seasons. The national reefer load-to-truck ratio typically runs 1.5 to 2 times higher than the dry van ratio, reflecting the structural tightness in refrigerated capacity.

Seasonal patterns significantly impact the reefer load-to-truck ratio. During produce season from April through September, the ratio in major growing regions can spike to 10:1 or higher as harvest volumes overwhelm available reefer capacity. During winter months, the ratio moderates as produce volumes decline and holiday demand for frozen goods subsides.

Shippers use the load-to-truck ratio as a planning tool to anticipate rate trends and capacity availability. When the ratio is trending upward, shippers should lock in contracted capacity, book loads further in advance, and consider building buffer inventory to reduce urgent shipping needs. When the ratio is trending downward, shippers have more negotiating leverage on rates but should maintain carrier relationships for when the market inevitably tightens again.
