The short answer
Florida trucks that never leave the state: the USDOT number and your legal name when it is 26,001 lbs or more (except farm vehicles).
Florida trucks that never leave the state need federal-style markings (name + USDOT number) at 26,001 lbs or more — counting GVWR, combined rating, OR actual weight, whichever crosses first. Under 26,001 and no placarded hazmat: exempt. Displaying a false or fraudulent identification number is a first-degree misdemeanor in Florida (316.302(12)).
Florida trucks that never leave the state: the USDOT number when it carries placard-level hazmat.
Florida trucks that never leave the state: your name and home town when it is a farm vehicle and is 26,001 lbs or more.

Eight Florida trucks, run through the checker
Each verdict below is what our free compliance checker returns for that truck using the verified Florida and federal rules. Where one changed fact flips the answer, we show the flip, because that is usually where Florida carriers get caught.
1. A 9,000-lb plumber's cargo van on Tampa service calls, Florida only
9,000 lbs GVWR · own tools and parts · Florida only
Not required
At 9,000 pounds it is under the 26,001-pound Florida line and it carries general freight with no placard, so no verified Florida or federal rule reaches it.

20,000 lbs combined · own equipment · Florida only
Not required
At 20,000 pounds it is under the 26,001-pound Florida line and it carries general freight with no placard, so no verified Florida or federal rule reaches it.
Flip one fact: The same rig takes one job in Georgia. It is now in interstate commerce, the federal rule applies from 10,001 pounds, and it needs the USDOT number and your legal name on both sides.
3. A 26,000-lb GVWR box truck delivering furniture for pay, Tampa only
26,000 lbs GVWR · paid freight · Florida only
Not required
At 26,000 pounds it is under the 26,001-pound Florida line and it carries general freight with no placard, so no verified Florida or federal rule reaches it.
Flip one fact: At 26,001 pounds, one pound more, the same truck needs the USDOT number and your legal name.
4. A 33,000-lb tandem dump truck for a Jacksonville contractor, Florida only
33,000 lbs GVWR · paid hauling · Florida only
USDOT number required
The Florida rule reaches this truck because it is 33,000 pounds, over the 26,001-pound line. The checker returns the USDOT number and your legal name, both sides. On the door that reads: USDOT 1234567 · Your Company LLC.
Flip one fact: Rated at 26,000 pounds, the same truck stays under the Florida 26,001-pound line: at 26,000 pounds no verified Florida rule reaches it.

40,000 lbs GVWR · farm vehicle · Florida only
Name + town required

6. A 15-passenger hotel shuttle van in Tampa, no fare charged

No verified rule
The verified Florida rule in our checker covers trucks that never leave the state when it is 26,001 lbs or more (except farm vehicles). We have not verified a Florida rule for passenger vans, and the federal rule only applies when a truck crosses state lines, so confirm with Florida Highway Safety and Motor Vehicles — Commercial Vehicle Enforcement or the FMCSA Florida Division, (850) 942-9338 before you leave this one unmarked.
7. A 14,000-lb placarded propane bobtail, Florida only
14,000 lbs GVWR · placard-level hazmat · Florida only
USDOT number required
The Florida rule reaches this truck because it carries placard-level hazmat. The checker returns the USDOT number, both sides. On the door that reads: USDOT 1234567.
Flip one fact: Haul non-placarded freight in the same truck and the hazmat trigger drops away: at 14,000 pounds no verified Florida rule reaches it.
8. A hotshot pickup and gooseneck running Tampa to Atlanta loads
26,000 lbs combined · paid freight · interstate
USDOT number required
Because it crosses state lines, the federal marking rule applies: it is 26,000 pounds, over the 10,001-pound line. The checker returns the USDOT number and your legal name, both sides. On the door that reads: USDOT 1234567 · Your Company LLC. Because it hauls for hire across state lines, the checker also lists the MC number as commonly displayed but not required.
Flip one fact: Keep the same rig inside Florida and the federal rule drops away: at 26,000 pounds no verified Florida rule reaches it.
The checker weighs rating, registered and actual weight, operation, for-hire status, cargo, passenger count and farm status. It does not model axle count or vehicle type, so if your truck is unusual, confirm with Florida Highway Safety and Motor Vehicles — Commercial Vehicle Enforcement.
What goes on the door in Florida
- Two markings, both sides of the power unit: USDOT 1234567 and Your Company LLC, which is the USDOT number and your legal name.
- No inch minimum in Florida. The legal standard is a color that contrasts with the truck and letters readable from 50 feet in daylight. We cut 2 and 3-inch letters, which clears that bar on any door.
- One set covers both rules. The Florida markings and the federal markings are the same two items, so a Florida-only truck that later picks up an out-of-state load does not need new decals.
- The USDOT number: Florida trucks that never leave the state when it carries placard-level hazmat (reads USDOT 1234567).
- Your name and home town: Florida trucks that never leave the state when it is a farm vehicle and is 26,001 lbs or more (reads Your Company LLC — Tampa).
Across the Florida line
The Florida line only matters while the truck stays home. One job in Georgia, or one load that starts or ends out of state, makes it interstate commerce, and the federal 10,001-pound rule applies no matter where either state draws its own line. For a truck that works near the border it helps to know how the neighbors differ for their own in-state trucks:
Neighbor lines come from the same verified rule files the checker uses; each state's page has its citations.
Who enforces it in Florida
Door markings in Florida are the business of Florida Highway Safety and Motor Vehicles — Commercial Vehicle Enforcement. Questions about your registration or number: (850) 617-2000, agency site. The federal side, USDOT numbers and the MCS-150, is the FMCSA Florida Division: (850) 942-9338, MCFLOFF@dot.gov. A marking violation is written at the roadside and follows the carrier on the inspection report, which is why it is worth getting the two lines right the first time.
