How does that fit in with “California” (CARB) emissions standards?
If you are a California resident and acquire a new car, truck, or motorcycle from another state, it must be certified to meet California smog laws to be registered in California. This includes certain diesel-powered vehicles. DMV cannot accept an application to register a vehicle in California that does not qualify for registration (California Health and Safety Code §§43150 - 43156).

Thats easy, they have been operating with a Waiver since CARB’s existence. The new head of the EPA has hinted he may not renew the waivers, that puts CARB officially out of business if he doesn’t grant the new waivers, everything, all regulations,laws,...gone.
