What are the California regulations governing a snowmobile engine?

In California, snowmobile engines must comply with the emissions standards set by the California Air Resources Board (CARB). These regulations include limits on exhaust emissions of hydrocarbons, nitrogen oxides, and particulate matter. Additionally, snowmobiles must be equipped with a functioning spark arrester to minimize fire hazards. Manufacturers must also provide certification that their engines meet these standards before sale in the state.
