Scale ticket notes Use a scale ticket to compare steer, drive, trailer, and gross numbers to Florida and federal limits before travel. inferred from official source medium

Florida weight checks should start with section 316.535, then move to FDOT if a permit may be required. Because Florida statutory wording depends on spacing and movement context, this page avoids reducing every axle-group question to a single shortcut number.

One Florida-specific point worth noting: the state single-axle limit under section 316.535 is 22,000 lb on non-Interstate roads, which is higher than the federal Interstate single-axle limit of 20,000 lb. Drivers running Interstate routes must use the federal 20,000 lb comparison; drivers on state roads may have the higher Florida statutory limit available, subject to the spacing and configuration provisions in the statute. The exact applicable limit depends on the road type and the axle configuration as described in section 316.535, not on a single universal number.

How to verify this yourself

Open section 316.535 for the legal weight language, then use FDOT’s OWOD permit page for any over-legal movement. For enforcement and penalty context, compare the FLHSMV page with the actual citation.

FAQ

Is a Florida scale ticket a permit?

No. It is a weight record. Permit authority comes through FDOT when required.

Which Florida agency handles overweight permits?

The FDOT State Permit Office handles over-weight and over-dimension permits.

Is Florida's tandem limit always the federal 34,000 lb number?

Interstate operation needs the federal comparison, while Florida statute includes spacing-specific provisions that should be checked directly.
