Heavy haul and oversize load trucking is the transport of freight that exceeds the legal size or weight limits for standard trailers. In Florida, any load wider, taller, longer, or heavier than the state’s standard limits requires special permits, specialized trailers, and often escort vehicles. Typical heavy-haul cargo includes construction and agricultural equipment, industrial machinery, boats, prefabricated structures, and transformers, moved on flatbeds, step-decks, lowboys, or multi-axle trailers.
When a load becomes oversize or overweight
Standard legal limits in Florida generally cap loads around 8.5 feet wide, 13.5 feet tall, and a gross vehicle weight of 80,000 pounds, with length limits depending on trailer type. A shipment that exceeds any of these thresholds is classified as oversize, overweight, or both, and cannot legally move without a state permit. Because Florida is a peninsula with major ports, heavy haul frequently connects PortMiami and Port Everglades to inland job sites.
What an oversize move requires
Permits
Florida requires trip permits for oversize and overweight loads, and the permit specifies the approved route, travel times, and any restrictions. Loads crossing state lines need permits for each state on the route.
Escorts and signage
Wider and longer loads require pilot or escort vehicles, oversize-load banners, and flags. Very large loads may need police escorts or utility coordination to move overhead lines.
Specialized equipment
Lowboys and multi-axle trailers spread weight to stay within axle limits and lower the deck height for tall cargo. Choosing the right trailer is central to a safe, legal move.
Route planning
Heavy-haul routes are engineered around bridge capacities, overpass heights, turn radii, and travel-time restrictions, often avoiding rush hours and certain roads entirely.
Why heavy haul needs an asset-based partner
Heavy haul has little margin for error: the wrong permit or an unsuitable trailer can strand a load or damage expensive equipment. An asset-based carrier with its own equipment and direct port access controls the move end to end. Go Freight combines heavy-haul and oversize transport with port drayage and warehouse staging, and supports complex shipments through project cargo logistics. For oversized imports arriving by sea, we also handle transloading at our bonded Miami facility.
Frequently asked questions
What is considered an oversize load in Florida?
In Florida, a load is generally considered oversize when it exceeds about 8.5 feet wide, 13.5 feet tall, or standard length limits, and overweight when gross vehicle weight exceeds 80,000 pounds. Such loads require a state permit and may require escorts.
Do oversize loads need escort vehicles?
Often, yes. Wider, taller, or longer loads require pilot or escort vehicles and oversize-load signage, and especially large loads may need police escorts or utility coordination, as specified by the permit.
What equipment is used for heavy haul trucking?
Heavy haul uses specialized trailers such as flatbeds, step-decks, lowboys, and multi-axle configurations that lower deck height and spread weight across more axles to stay within legal limits while carrying oversized or overweight cargo.
