Time running out for CARB Compliance on trailer aerodynamics

As New York's famous Times Square Ball drops at midnight, a global audience of more than 1 billion will watch New Yorkers ring in the New Year

While the CARB mandate might seem to be heavy-handed government at work, Graham said that in this case in particular, aerodynamic fairings on trailers have a very fast payback. "We've worked with many large fleets which have documented real-world fuel savings of up to four percent with our skirts," he said. "In testing, at sustained speeds, our SAE testing has shown up to a seven percent improvement. If you do the math, our skirts can have a payback in as little as 35,000 miles of trailer utilization. It's one of the fastest paybacks in the trucking industry."

According to Rhondeau, owners, drivers, fleet operators, California-based brokers, California-based shippers and motor carriers should be fully aware of all the rules.

CARB will allow a one-time per fleet per year (one tractor) exemption into the state for a trucking company or owner operator, but the request must be to the CARB via an email or written request and approved before entering California. 

In addition, if registered with CARB, local haul 53-foot trailers are exempt from the aerodynamic requirements of the rule, but they must not go beyond 100 miles from their home base. Empty trailers are also exempt. Short haul tractors and the trailers they pull are exempt but the tractor must be entered into CARB's data base and tractor mileage must be 50,000 miles or lower per year.
