When Is a Permit Required?
A permit may be necessary when the loaded vehicle exceeds Florida's applicable dimensional or weight limits. The Florida Department of Transportation (FDOT) State Permit Office handles oversize and overweight permitting for state-maintained highways.
FDOT currently offers several permit types, including:
- Annual blanket permits
- Annual vehicle-specific blanket permits
- Ten-day trip permits
- Three-month route-specific blanket permits
Trip and route-specific permits require a defined travel route.
Heavy Equipment That May Require a Permit
Common examples include:
- Excavators
- Bulldozers
- Wheel loaders
- Backhoes
- Cranes
- Motor graders
- Large forklifts
- Mining equipment
- Construction machinery
- Specialized agricultural equipment
- Large generators and industrial equipment
Whether a permit is required depends on the actual dimensions, weight, vehicle configuration, and applicable exemptions.
Measuring the Equipment
Before applying, carriers should determine the complete loaded dimensions, including the truck, trailer, and machinery.
Important measurements include:
Width: Measure the widest point of the loaded combination.
Height: Measure from the road surface to the highest point of the equipment.
Length: Measure the overall length of the vehicle and load.
Weight: Determine the gross weight and axle weights, including axle spacing.
These measurements are important because FDOT evaluates permit requests based on factors such as whether the load can reasonably be dismantled, traffic safety, potential roadway damage, and bridge structural limitations.
Florida Self-Issued Trip Permits
Some qualifying loads can be handled through FDOT's Permit Application System (PAS). FDOT states that self-issued trip permits are available for loads up to 16 feet wide, 18 feet high, 150 feet long, and 200,000 pounds, with a lower 140,000-pound limit for self-propelled equipment. The GIS feature in PAS must be used for self-issued permits.
This can be particularly useful for certain heavy equipment movements that fall within the applicable self-issue limits.
Route Planning Is Important
A permit does not necessarily mean that the equipment can travel on any road in Florida. Route restrictions, bridge limitations, construction conditions, and other restrictions can affect the approved route.
FDOT publishes current route-restriction information and provides routing resources, including overweight routing maps, posted bridge information, the FDOT Interactive Project Map, and FL511.
For very tall equipment, vertical-clearance considerations are especially important. Florida's permit criteria specifically address available vertical clearance for proposed routes involving loads over 18 feet high.
Escort and Safety Requirements
Depending on the size and configuration of the load, the permit may include requirements for warning signs, flags, escort vehicles, travel restrictions, and other safety measures.
FDOT's current permit movement conditions contain specific escort-equipment and movement requirements. Carriers should review the conditions attached to the individual permit before beginning the trip.
What Happens Without the Proper Permit?
Operating an oversize or overweight vehicle without the required special permit can create enforcement and financial risks. Florida law requires the applicable permit to be obtained before the vehicle or load operates on a public road.
Carriers should also remember that permit requirements can differ depending on whether the vehicle is traveling on a state-maintained highway or a road under another jurisdiction's authority.
Final Thoughts
Transporting heavy machinery in Florida requires careful planning. Before moving an excavator, crane, bulldozer, loader, or other large piece of equipment, carriers should verify the loaded dimensions and weights, determine the appropriate permit type, check the proposed route, and review all permit conditions.
