Florida DOT Compliance: What Changes for Intrastate Trucks and What Never Does

Who this guide is for

This guide is for Florida owner-operators, small fleets, and safety managers who need to know which rules apply to their trucks and drivers, and what Florida enforcement focuses on. Florida is home to 30,969 interstate carriers in FMCSA's census, the fifth-largest count of any state, and 88.9% of them run 10 or fewer power units. The census also lists 115,923 intrastate carriers based in Florida, which is why the intrastate rules below matter to so many operators.

If you only run intrastate, read the next two sections closely. If you run interstate at all, the federal rules are your baseline, and our national pages on hours of service and driver qualification files apply as written.

Federal rules vs Florida intrastate rules

Florida law (s. 316.302(1)(b)) applies 49 CFR Parts 382 to 386 and 390 to 397 to intrastate commercial motor vehicles, then carves out specific differences. The main ones:

What the Florida differences mean in practice

Three practical consequences. First, an intrastate truck under 26,001 pounds is not rule-free: drug and alcohol testing (Part 382), driving rules (Part 392), and equipment rules (Part 393) still apply. Second, the longer hours only help on trips that stay in Florida; a driver who takes one load into Georgia is back under the federal 11 and 14. Third, because the adoption date is fixed, Florida intrastate carriers should not assume a federal change that took effect after 2023 applies to them, or that it does not. That needs checking rule by rule, and the legislature can move the date in any session.

Florida also keeps narrow exceptions for agricultural, horticultural and forestry hauling, a 1988 driver-salesperson grandfather clause, and a vision exception for some intrastate drivers with clean records who carry a physical examination form dated within 24 months. Each has conditions in the statute; read them before relying on one. Our interstate vs intrastate guide explains how the line between the two is drawn.

Who enforces trucking safety in Florida

Roadside inspections and commercial vehicle enforcement in Florida are carried out by the Florida Highway Patrol's Office of Commercial Vehicle Enforcement, part of the Department of Highway Safety and Motor Vehicles (FLHSMV). The former Office of Motor Carrier Compliance moved into FHP on July 1, 2011, so older references to "Motor Carrier Compliance" or FDOT weigh-station officers are out of date.

Florida law also sets a civil penalty for interstate or intrastate carriers that fail to register under 49 CFR 390.19 (s. 316.3025). We do not quote the amount here because it can change; check the current statute.

USDOT numbers and registration for Florida carriers

FLHSMV states that companies operating commercial motor vehicles must register for a USDOT number and display it on power units and intermodal chassis, and that registration fees are not charged to companies engaged solely in intrastate operations. The same page lists an exemption from USDOT registration for intrastate vehicles with a declared gross vehicle weight under 26,001 pounds hauling property that does not require placards (s. 316.302(2)(f)).

Interstate carriers also need the federal credentials that apply to their operation (operating authority for for-hire interstate carriers, UCR, and IFTA/IRP where they apply). Our guides to UCR registration and FMCSA operating authority cover those. Intrastate household goods movers and moving brokers must register with the Florida Department of Agriculture and Consumer Services under chapter 507, Florida Statutes.

What Florida roadside inspections find

Florida's inspection profile is unusual: lighting dominates. The two most frequent violation groups at Florida-reported inspections are clearance and identification lamps and general lighting, ahead of brakes. Vehicle inspections recorded at least one maintenance violation 56.2% of the time, above the national 48.9%, while hours-of-service violations showed up on 5.0% of driver inspections, below the national 7.8%.

Source: Fleet Regulators analysis of FMCSA Safety Measurement System (SMS) input files, monthly run published October 2026, covering roadside inspections recorded September 25, 2024 to September 24, 2026. "In the state" means the inspection was reported by Florida, whatever the carrier's home state. Driver rates use Level 1, 2, 3 and 6 inspections; vehicle rates use Level 1, 2, 5 and 6. Group names are FMCSA's. Same method as our HOS roadside violations study.

Florida-based interstate carriers, wherever they were inspected, had a driver out-of-service rate of 8.7% and a vehicle out-of-service rate of 23.5%. These figures describe what inspectors recorded, not how safe carriers in the state are. Rates move with enforcement priorities, which inspection levels a state favors, where it inspects, and which carriers pass through.

The practical reading: in Florida, the cheapest violations to prevent are the most common ones. A working pre-trip that actually checks every lamp, and a shop habit of fixing lighting the same day, address the top two groups directly. Our roadside inspection checklist and Vehicle Maintenance BASIC guide explain why those small items carry real CSA weight.

Where Florida carriers get caught out

• Running intrastate hours on an interstate load. The 12/16 limits disappear the moment a trip crosses the state line or a load requires hazmat placards. Dispatch has to know which rulebook each run is under before the driver starts.
• Assuming "under 26,001 means exempt." Lighter intrastate trucks still need drug and alcohol testing where Part 382 applies, safe-driving compliance, equipment that meets Part 393, and the Part 396 duties to inspect, repair and act on roadside inspection reports.
• Using the short-haul log exemption without meeting its conditions. The Florida exemption depends on the 150 air-mile radius and the 395.1(e)(1)(iii) and (iv) conditions; drivers outside them need records of duty status.
• Lamps and markings. The inspection data says it plainly: lighting is Florida's most common finding.
• Old references. Training material that still cites FDOT Motor Carrier Compliance, or federal limits for intrastate drivers, is out of date in both directions.

Florida compliance checklist

• Classify every vehicle: GVWR/GCWR above or below 26,001 lb, placardable hazmat or not, interstate or intrastate.
• Record, per trip, whether the driver is under federal Part 395 or Florida's intrastate limits.
• Confirm drivers using the 150 air-mile log exemption meet every condition; everyone else keeps ELD or paper logs as required.
• Keep a complete driver qualification file (see the DQ file checklist) for each driver, including medical certification.
• Enroll covered drivers in a drug and alcohol program and run Clearinghouse queries.
• Display the USDOT number on power units and keep the MCS-150 current.
• Check lamps, reflectors and markings on every pre-trip; repair lighting the same day.
• Keep annual inspection records for each vehicle (what to keep).
• Recheck s. 316.302 after each legislative session for a new adoption date.

How Fleet Regulators supports Florida carriers

We work with Florida carriers remotely from Austin, Texas. We have no Florida office, and none of this work needs one: daily log reviews run through your ELD provider's portal, driver files live in a shared system, and audit preparation happens on scheduled calls with document checklists.

For Florida fleets that means: sorting out which trips run under intrastate or federal hours and auditing logs against the right limits (HOS log auditing); building and maintaining driver qualification files; preparing for a compliance review or audit or a new entrant safety audit; and working down maintenance and lighting violations that drive CSA scores. Carriers that want the whole safety function handled use our fractional safety department.
