Florida Oversize Load Permits, Regulations & Axle Rules

Florida's permitted-load clock runs from one-half hour before sunrise to one-half hour after sunset. That window applies to every oversize dimension category, width, height, and length, but the secondary restrictions stacked on top vary enough by dimension that it's worth thinking about each separately.

For width, loads up to 10 feet wide may run any day during daylight. Once you cross 10 feet, Saturday and Sunday movement is cut to a half-day: from one-half hour before sunrise until noon only, not a full prohibition but not a full day either. The same partial-weekend rule applies through the full width range up to 16 feet. Seven holidays are full blackouts: New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, the day after Thanksgiving, and Christmas. Unlike most states, Florida separately prohibits the Friday before any holiday that falls on a Saturday and the Monday after any that falls on a Sunday.

From 12 feet wide, and separately from 85 feet long, a congested-area peak-hour ban also applies: no movement in congested areas during peak traffic hours. Florida does not publish a separate roster of city-specific curfew windows the way Texas does, but the peak-hour restriction functions like a rolling urban curfew wherever FDOT determines congestion applies. Loads over 16 feet wide are limited to local moves within a 50-mile radius of the origin, so the peak-hour and weekend restrictions become less relevant at that width; the routing constraint is the binding one.

Height follows a different pattern. Loads at or below 14'6" face no day or hour restrictions at all; they can move around the clock, seven days a week. Loads over 14'6" up to 16 feet drop into the daylight-only, no-weekend/holiday framework. Loads over 16 feet are also restricted to local moves, mirroring the width rule.

Nighttime movement exists but isn't the carrier's choice. It's only allowed when FDOT's District Traffic Engineering Office recommends it or the Office of Maintenance makes it a permit condition. When nighttime travel is approved, law enforcement escort is mandatory; there's no permit-office-approved nighttime window a carrier can self-elect into. Rear overhang during nighttime movement is capped at 10 feet unless the permit says otherwise.

Poor weather stops movement entirely. No travel is allowed when horizontal visibility drops below 1,000 feet. Any vehicle already underway when conditions deteriorate must exit at the first available location and park until visibility recovers. Florida sets no continuous 24-hour movement provision for any load type.

Florida treats several commodity types distinctly from the general oversize rules, with relief that's meaningful in practical terms.

Farm equipment, implements of husbandry, agricultural trailers, and forestry equipment are exempt from oversize permit requirements when the move is non-commercial, but the exemption does not extend to weight. Any farm or ag unit exceeding weight limits must obtain an overweight permit. The width and height limitations in Florida's vehicle code do not apply to farming or agricultural equipment when it's temporarily operated during daylight hours on a public road that is not a limited-access facility. When a permit is required, the fee is nominal: $5.00 trip or $17.00 annual, local moves only.

Poles, structural objects, and unprocessed logs carry length exemptions. Truck-tractor combinations or pole trailers hauling poles or structural objects that cannot readily be dismembered are exempt from length limitations as long as the vehicle and load do not exceed 75 feet overall, operation is daylight only excluding weekends and holidays, and flags are displayed at the extreme ends. Unprocessed, tree-length logs qualify for the same 75-foot overall exemption on a daytime-only basis. Utility poles transported by government or public utility vehicles run up to 120 feet overall under a length exemption, but any combination over 75 feet must carry warning lights and requires an escort to assist with turns in city limits.

Horticultural trees may overhang up to 10 feet beyond the rear of the vehicle, provided root balls are on the floor or toward the front of the trailer, trees rest against a retaining bar, and the overhanging portion is covered with protective fabric.

Auto and boat transporters operate under Florida's legal length framework rather than general trailer length caps. A stinger-steered automobile transporter is legal up to 80 feet overall excluding the load; a stinger-steered boat transporter goes up to 75 feet. Non-stinger auto and boat transporters top out at 65 feet excluding the load. An auto or boat transporter semitrailer running on a permit may have its load extend up to 6 feet beyond the rear of the trailer. Automobile transporters also get a slightly higher legal height, 14 feet including load versus the 13'6" standard.

Sealed containerized cargo moved in conjunction with a maritime shipment is treated as nondivisible and may operate at up to 95,000 lbs gross vehicle weight with a minimum of five load-bearing axles, an outer bridge span of at least 51 feet, and no straight trucks or hazardous materials.

Mobile cranes operating under a special blanket permit may run up to 12 feet wide, 14'6" high, and 100 feet long, and uniquely may operate on and off the Interstate Highway System at all hours; the travel-time restrictions that otherwise apply to oversize loads do not apply to cranes under this permit. The crane blanket also authorizes exceeding the statutory weight limits when the crane's design for special use requires it.

Wreckers towing disabled vehicles must keep the combined gross weight at or below 140,000 lbs and the combined overall length at 135 feet or less. The escort requirement follows whatever the original permit for the towed vehicle specified.

Florida does not use the term "superload." The functional equivalent is the Non-Routine Permit, the threshold above which the Florida Department of Transportation's (FDOT) Permit Office must manually review a move rather than letting the carrier self-issue through the online Permit Application System (PAS).

Self-issue through PAS is available for loads up to 16 feet wide, 18 feet high, 150 feet long, and 200,000 lbs gross (140,000 lbs for self-propelled equipment). Once any dimension or weight crosses those ceilings, the application must go directly to the Permit Office for processing. Above 16 feet wide, permits are also referred to FDOT's District Traffic Engineering Office for review.

The hard structural-evaluation trigger is 200,000 lbs gross. At that point the move is also trip-permit only, no annual permit available, and the applicant must submit a schematic of the vehicle showing all longitudinal and transverse axle spacings, individual axle weights, and overall dimensions. That schematic must reach the Permit Office at least 10 business days before the proposed move date so FDOT's Bridge Section can perform a structural analysis of the route's load-bearing capacity. Loads under 200,000 lbs may still be subject to a structural analysis if a Bridge Section engineer determines one is needed given the configuration.

For loads that exceed what any existing rule authorizes, dimensions or weights not specifically covered by statute or FDOT rule, a separate override authority exists. The Governor, Secretary of Transportation, Assistant Secretary for Engineering and Operations, or State Highway Engineer may authorize the Permit Office to issue a permit in extenuating circumstances, provided the applicant submits a letter of essentiality from a government entity or the ultimate recipient of an essential service. This channel is narrow and reserved for genuinely unusual situations.

Florida has no published separate fee for the non-routine process beyond the standard trip permit fee, but the 10-business-day minimum means a structural move requires planning well ahead. There are no dedicated superload travel windows: loads above the structural-evaluation threshold that are approved move during ordinary permitted daylight hours with whatever escort conditions the permit specifies. Law enforcement is required for any approved nighttime movement.

Florida splits clearance responsibility between the carrier and FDOT. The department verifies the load-carrying capacity of bridges and structures along the proposed route. The carrier, or applicant, verifies that adequate vertical and horizontal clearances exist at every point on the route.

A route survey must be performed prior to movement for all oversized loads. The survey must be conducted by a qualified escort as defined in FDOT's administrative code, or by a driver holding a valid CDL. When the load exceeds 15 feet in height or 16 feet in width, the carrier must have a Survey Letter on board and present it to law enforcement or weight inspectors on request.

Two categories of load trigger a written affidavit in addition to the survey. For loads over 15 feet high, the applicant must submit an affidavit on company letterhead confirming the route has been surveyed and that every vertical clearance exceeds the requested permitted height by a minimum of 6 inches. For loads over 22 feet wide, the affidavit must confirm adequate horizontal clearance throughout, with at least 2 feet of clearance on each side of the load.

On the structural side, the bridge analysis described above under the non-routine permit process functions as the route's structural survey. For loads over 200,000 lbs, that structural evaluation must be completed before the permit is issued, meaning the route's load-carrying capacity is locked in before any wheels turn, not checked after the fact.

Once a route is approved and a permit issued, it binds the move. The permit must be in the vehicle during the move. Deviating from the approved route is not permitted. On the height side, loads over 16 feet require utility personnel to be present whenever the route encounters low barriers such as overhead structures, traffic signals, or low wires, which effectively builds a second layer of route-specific clearance work into the move itself.

Florida's law-enforcement escort triggers are fixed and codified, not discretionary. Three dimensional thresholds require Florida Highway Patrol (FHP) or another qualified law enforcement officer, and one travel-condition trigger applies universally.

By width: any load over 16 feet wide requires law enforcement escort for all moves. These loads are also capped at local moves within a 50-mile radius, so the escort accompanies a geographically constrained route.

By height: any load over 16 feet high requires one law enforcement escort plus one civilian qualified escort, with the lead escort preceding the load and carrying a vertical height indicator.

By length: loads over 250 feet in overall combination length require one law enforcement escort plus one civilian qualified escort.

By travel condition: any approved nighttime movement requires law enforcement escort, regardless of the load's dimensions. There's no permitted nighttime window that runs with civilian escorts only.

Under Florida's administrative code, a qualifying law enforcement escort means any police officer as defined in state law, operating a vehicle owned by a law enforcement agency and using blue or red-and-blue warning lights. The agency is most commonly FHP, Florida Highway Patrol, though local law enforcement officers meeting the definition also qualify.

Civilian qualified escorts cover the bulk of the escort range below those police thresholds. Loads between 12 and 14 feet wide need one civilian escort (front on two-lane roads, rear on four-lane divided highways). Loads between 14 and 16 feet wide require two civilian escorts, one front and one rear. Loads between 14'6" and 16 feet high require one civilian escort in front carrying a non-conductive, non-destructive height pole set at least 6 inches above the load. Loads over 95 feet long require one civilian escort in the rear. Loads over 150 feet long require two civilian escorts on non-limited-access roads, or one on limited access. Escorts must maintain radio contact with the load driver at all times and may not bypass weigh stations.

Florida does not specify a dedicated scheduling channel for police escorts separate from the permitting process. The permit authorizes the move and specifies its escort conditions; carriers coordinate law enforcement coverage through FHP for the approved route and travel dates.
