Mullen Automotive received California Air Resources Board (CARB) certification for its all-electric Class 3 low cab forward chassis truck. The certification is awarded to vehicle manufacturers who meet specific emissions standards in compliance with CARB regulations. The District of Columbia and 14 states, including California, have adopted vehicle standards under Section 177 of the Clean Air Act (42 U.S.C. §7507), which requires additional approvals beyond EPA regulations, Mullen said.
