The California Air Resources Board (CARB) has adopted a regulation to improve the fuel efficiency of combinations of heavy-duty tractors and 53' trailers through implementation of tractor and trailer aerodynamics and low rolling-resistance tires. The regulation is officially the Heavy-Duty Vehicle Greenhouse Gas Emission Reduction Regulation.Read More
U.S. EPA SMARTWAY:
The U.S. Environmental Protection Agency SmartWay Transport Partnership (SmartWay) is a voluntary program of government and the freight transportation industry to reduce greenhouse gas emissions and improve fuel efficiency.

SAE J1321 TESTING:
The Joint TMC/SAE Fuel Consumption Test Procedure Type II – often called SAE J1321 testing, a reference to its document number in the Society of Automotive Engineers library – is the industry standard for measuring increases in fuel efficiency attributable to aerodynamic technologies.
FUEL SAVINGS CALCULATOR:
Trucking is a carbon-intensive business. U.S. commercial trucks burn roughly 50 billion gallons of fuel each year. The good news? Trailer aerodynamics is among the most cost-effective means of mitigating climate change and achieving energy independence.

Aerodynamic drag is a function of squared velocity. At highway speeds, it accounts for approximately 65% of the fuel consumed by a tractor-trailer.
The four major areas of aerodynamic drag on a tractor-trailer are the:
Judged by performance, reliability or any other measure, the TrailerTail® is the most advanced rear-drag reduction technology on the market. In 2008 it became the first and still the only rear fairing to be validated for fuel efficiency by the U.S. EPA based on SAE testing.
