Heavy Haul Is the Most Quote-Sensitive Mode in Florida
Two carriers can quote the same heavy haul move from Miami to Jacksonville and come back with prices that differ by 30 percent. The base equipment is similar. The fuel cost is similar. What separates the quotes is how the carrier handles the permit, the routing, and the escort coordination. Get those wrong and the move costs more, takes longer, and risks a roadside violation. Get them right and a heavy haul move runs as predictably as a standard dry van.
Where the Permit Triggers Sit
Florida heavy haul permits are issued by the Florida Department of Transportation and triggered when a load exceeds any of the legal limits set in Section 316.515 of the Florida Statutes. The most common triggers are width over 8 feet 6 inches, height over 13 feet 6 inches, length over the trailer-specific maximum, and gross vehicle weight over 80,000 pounds.
Loads that exceed only one of those dimensions usually qualify for a single-trip permit issued within the same business day. Loads that exceed multiple dimensions, particularly weight combined with width or length, move into the superload permit category, which requires advance engineering review of the route. A superload permit application that lands on FDOT’s desk on a Monday might not have a route approved until Wednesday or Thursday.
The lesson for shippers: lead time on heavy haul is a function of how many limits you exceed, not how heavy the load is in isolation.
Routing Is Where Costs Hide
A heavy haul route is rarely the shortest path. FDOT will approve a route that avoids low bridges, weight-restricted county roads, school zones during start and end times, and active construction. The approved route from Miami to Tampa for an over-height load may add 40 miles to the trip compared to a standard truck route. Those extra miles are pure cost.
Bridge clearance is the variable that surprises shippers most often. Florida has dozens of bridges with vertical clearances below 14 feet 6 inches, and the published clearances are not always conservative. A reputable heavy haul carrier maintains its own clearance survey for the routes it runs frequently and treats the FDOT-published number as a starting point, not a final answer.
Weight-restricted roads are the other quiet routing constraint. Some Florida county roads carry posted weight limits below the state maximum, particularly in rural agricultural counties. A route that crosses one of those segments needs either a county permit on top of the state permit or a reroute around it.
Escort Requirements
FDOT requires escort vehicles based on dimension thresholds defined in the Florida Trucking Manual. The general rules: one front escort is required when width exceeds 12 feet, height exceeds 14 feet 6 inches, or length exceeds 95 feet. A rear escort is added when width exceeds 14 feet or the load creates a sight obstruction. Loads over 16 feet wide or 17 feet high typically require law enforcement escort, which is coordinated through the Florida Highway Patrol.
Escort costs in Florida currently run roughly $1.85 to $2.25 per mile per civilian escort vehicle, with FHP escorts billed at the trooper rate plus vehicle. On a 350-mile move from Miami to Jacksonville with two civilian escorts, escort cost alone can run $1,300 to $1,600 before any permit or pilot car coordination fees.
Time-of-Day and Time-of-Year Restrictions
Florida heavy haul permits include movement restrictions you have to plan around. Most oversize permits prohibit movement after sunset and before sunrise. Permits in Miami-Dade, Broward, and Palm Beach counties prohibit movement during weekday peak hours from 7 AM to 9 AM and 4 PM to 6 PM. Holiday weekends from Memorial Day through Labor Day have additional restrictions on heavy haul travel through tourist corridors.
The restrictions are not just compliance theater. A permit movement that is caught violating a time restriction triggers fines that can exceed the cost of the move itself.
What a Quote Should Show You
A heavy haul quote that has been built carefully will show you the equipment type, the per-mile rate, the permit fee, the escort cost broken out by vehicle, the routing assumption, the time-of-day window, and the contingency for weather or route changes. A quote that bundles everything into a single per-mile number is almost certainly missing something that will reappear as an accessorial after the move is complete.
Go Freight Runs Permitted Florida Heavy Haul on Its Own Equipment
Go Freight operates low boy, Landoll, step deck, RGN, and flatbed trailers with dispatchers who handle FDOT permitting, route engineering, and escort coordination as part of the quote. Loads up to 80,000 pounds GVW move on our own equipment with our own drivers. Superloads and project cargo are coordinated end to end.
