Highway Motorcycle Certification Requirements

This page last reviewed October 16, 2014

This page provides a list of emission-related regulations, test procedures, Manufacturers Advisory Correspondences (MACs), and related documents applicable to highway motorcycles (HMC), also known as on-road or "street" motorcycles, and is primarily for the interest and needs of manufacturers and others that are required to obtain certification from ARB. For more public-oriented materials, please visit our On-Road Motorcycle Regulation page.

Please sign up to the new Mobile Source Mailouts and MAC list server. By doing this, you will be notified when a new Mobile Source Mailout (e.g. proposing a new rule or amending an existing rule) or MAC (e.g. providing ARB's policy decisions and interpretations of the regulations and test procedures) has been posted to the Mobile Source Mailouts or MAC webpages. These email notices can replace any of the mobile source hard copy mailing lists you may already be on.
