Lowboy Auto Hauler Fairness Act of 2025
Sponsored By: Representative Barrett, Tom [R-MI-7]
In Committee
Summary
Creates an explicit under-80-foot length limit for certain truck tractor–lowboy trailer combinations and exempts lowboy trailers from rear-overhang flag rules. The bill also defines “lowboy trailer” as a semitrailer with a depressed section used to transport assembled highway vehicles and ties that definition into title 49 length rules.
Show full summary
- Truck drivers and auto haulers: Establishes a maximum length of less than 80 feet for a truck tractor–lowboy trailer combination when the front overhang is under 4 feet and the rear overhang is under 6 feet. The limit applies even if the truck tractor cannot or would not use overhangs to carry cargo.
- Lowboy trailer operators: Removes the requirement to use rear overhang flags under 49 C.F.R. 393.87 for vehicles meeting the new lowboy definition.
- Regulators and carriers: Adds a formal legal definition of “lowboy trailer” in title 49 so the length and flag rules apply specifically to those semitrailers.

New length and flag rules for lowboy haulers
This bill would set clear size rules for auto haulers using lowboy trailers. A tractor plus lowboy trailer would be limited to under 80 feet when the front overhang is under 4 feet (measured from the rear of the tractor to the front of the trailer) and the rear overhang is under 6 feet. This limit would apply whether or not the tractor can carry cargo to use those overhangs. Lowboy trailers that meet the definition would be exempt from the federal rear overhang flag rule. These changes would take effect if and when the bill is enacted.
