CARB website tells truck owners whether they're GHG-rule compliant

Truck owners have a new tool they can use to tell if they’re compliant with California’s Tractor-Trailer Greenhouse Gas Regulation, also known as the CARB SmartWay rule.

CARB recently announced its website to help truck driver sand freight shippers determine whether they’re within the SmartWay regulation’s requirements. The site is available by clicking here.

The site can be reached by computer, mobile phones or tablets and can be used to search for a trailer by VIN or license plate number.

“This website will be most helpful for users in the field that need to know whether a trailer currently not equipped with aerodynamic devices may be operated legally in California at any given point in time,” CARB said in an informational email.

Trailer that aren’t retrofitted and aren’t reported on the website may still be compliant, CARB says, as long as the trailer:
Is traveling empty;
Is being pulled by tractors registered with CARB as short or local haul;
Has a pass or is being pulled by a tractor with a pass (with a copy on trailer or with driver);
Is a 2003-2009 model year reefer with a 2003 or newer reefer model year engine.

Storage trailers are exempt from the regulation.

Designed to lower greenhouse gas emissions, CARB’s SmartWay Rule began enforcing a specific combination of aerodynamic additions to 53-foot trailers and reefers in January 2013.

By 2017, the rule requires all trucking companies to have installed low-rolling-resistance tires on trailers and reefers with 2010 and older model years. 2011 and newer model year trailers are already required to have aerodynamic equipment installed.

Last summer, CARB said only 200 to 300 small trucking fleets nationally had signed up on CARB’s GHG rule registry – which allowed them to gain additional compliance time. The relatively low signup numbers fueled concerns that few small companies were aware of the rule.

The rule applies to owners of trailers, motor carriers, truck drivers, California-based shippers and California-based brokers.
