Making Roads Safer, Protecting the Environment, and Strengthening the Economy through Vehicle Weight Limit Reform.

CTP Supports federal legislation giving states the option to set higher Interstate weight limits for trucks equipped with six axles.


Cleaner Environment

The U.S. DOT estimates that raising the federal weight limit would result in a decline in fuel use, carbon dioxide emissions and emissions of nitrogen oxide.


Improved Infrastructure

By lowering axle weight limits, truck weight reform would reduce pavement costs by as much as 4.2 percent, according to the U.S. DOT.


Stronger Economy

Raising the federal vehicle weight limit will allow American producers to reduce the number of shipments needed to deliver a fixed amount of goods—making them more productive and competitive.



Since the U.K. similarly raised its weight limit for six-axle vehicles in 2001, fatal truck-related accidents have declined by 35%. Properly designed heavier trucks can be used safely in the U.S.
