Heavy-Duty Certification Program - Approvals
This page last reviewed February 22, 2013
The ARB is required to certify all on-road vehicles. The certification†protocol and test procedures for zero-emission heavy-duty vehicles (HD-ZEV) with gross vehicle weight ratings (GVWR) above 14,000 pounds are in the development process. The ARB encourages manufacturers to participate in the regulatory process to formulate the certification protocols and test procedures for HD-ZEV. Prior to the finalization and adoption of HD-ZEV certification protocols and test procedures, heavy-duty electric vehicles may be approved for sale in California based on the manufacturer demonstrating that the vehicles do not emit any vehicle exhaust emissions or fuel-based evaporative emissions.
