Produce and perishable freight accounts for roughly $48 billion in annual US trucking revenue, with over 3.1 million reefer loads moved each year. California's Central Valley alone ships 250+ commodities across 6.8 million acres of farmland, generating outbound loads that pay $3.10-$3.60/mile during peak harvest from April through October. Florida and Georgia round out the top three origin states, with winter strawberry and citrus runs from Plant City and Vidalia onion season creating rate spikes of 20-35% above baseline.

The US automotive freight market moves $120+ billion in parts and finished vehicles annually, with 1.2 million truckloads of components flowing between 300+ assembly plants and 4,000+ tier-1 suppliers each month. Michigan-to-Tennessee and Ohio-to-Texas corridors dominate, with JIT parts loads paying $2.90-$3.40/mile and finished vehicle transport on car haulers averaging $0.55-$0.70 per mile per unit. Assembly plant shutdowns during model changeovers (typically July and December) create predictable freight dips of 25-35%.

Construction freight represents a $78 billion annual market in US trucking, moving 2.8 billion tons of aggregates, steel, concrete, and building materials each year. Flatbed and step deck dominate — 70% of construction loads require open-deck equipment — with per-mile rates averaging $3.25-$3.80/mile for tarped loads. The market tracks closely with housing starts (1.4 million in 2025) and federal infrastructure spending ($550 billion from the IIJA), making it one of the most predictable high-paying freight categories when you know the seasonal cycles.
