ONMC - Executive Order Introduction
Contact
In order for an On-Road Motorcycle (ONMC) to be introduced into commerce in California for use on public roads, the California Air Resources Board (CARB) must first issue an Executive Order for the particular make, model, and model year, certifying that it has met the applicable emission standards.
For certification purposes, vehicles are grouped in engine families or test groups for exhaust emissions (hereinafter, engine families) and evaporative families for evaporative emissions. Within each family, vehicles share similar designs and are expected to have similar emission characteristics. To be certified, the manufacturer of an ONMC must demonstrate that its exhaust and evaporative emission control systems are durable and comply with the emission standards for the vehicle's useful life. Applications for certification must be submitted to, and approved by CARB. Once the testing is completed by the manufacturer, or an independent laboratory of their choosing, the data is reviewed by CARB staff. If the data produced by the manufacturer shows that the ONMC is in compliance with all of the applicable standards, certification is then issued by CARB.
ONMC Certification Information
Executive Orders typically include all pertinent certification information such as the vehicle model year, engine and evaporative families, emission control systems, vehicle models, etc. Production vehicles must be identical in all material respects to those (of the certification vehicles) for which the certification was granted. Production vehicles must also be properly labeled and have their emission control systems warranted for their specified useful life. New and customer-owned production vehicles are subject to compliance testing by either the manufacturers or CARB. Additionally, warranty repairs must be reported by the manufacturers to CARB. Either of these can result in remedial actions if CARB determines the vehicle is not in compliance.
