The Coalition

The Coalition for Transportation Productivity (CTP) is a coalition of 200 shippers and allied associations dedicated to giving states the flexibility to safely confront highway capacity issues by utilizing more productive, six-axle trucks on Interstate highways within their borders.

CTP advocates for heavier - not bigger - six-axle trucks that meet the same safety standards as trucks currently allowed on interstates.

Raising interstate weight limits for six-axle tractor-trailers would effectively help address the safety, economic and environmental challenges facing our nation's freight transportation network. CTP supports a user fee on units equipped with the additional axle that would be used for bridge repair.
