To amend title 23, United States Code, to establish a safety data collection program for certain 6-axle vehicles, and for other purposes.

HR 3372 establishes a 10-year pilot program allowing specific heavy trucks (6-axle vehicles weighing up to 91,000 pounds) to operate on interstate highways under state permits. States must apply to join the program, issue permits with route restrictions, and require operators to report accidents, vehicle weight, and annual mileage. Participating states may reduce permit fees by 67% for trucks equipped with automatic emergency braking systems. The program mandates annual safety reports to the federal government and ensures no reduction in highway funding for states participating in the pilot.
