New Vehicle and Engine Certification: Executive Orders for Off-Road Spark-Ignited Engines and Equipment

Contact

The New Vehicle and Engine Certification Program is responsible for the certification of new engines, vehicles, powertrains, aerodynamic devices and other new certifications.  Vehicles and engines may be sold and otherwise produced in California only if approved by Executive Order (EO) after review by CARB.  Executive Orders are issued for on-road and off-road categories.

Scanned copies of issued Executive Orders may be requested via email.

CARB has issued Executive Orders for the following off-road spark-ignition engine categories and years. Additional certification information, summarized in the supplemental EO Summary files, is available for each category.
