I live in San Diego County and have a CHP officer living in my neighborhood. He has told me they are going after people who have the Montana, South Dakota and Vermont tags on their cars. Vermont has recently, I have been told, stopped selling the Vermont titles and plates. What he told me, was that if you are in the military, then it is okay to have out of state plates, but if you driver's license is from California and you are a resident of California, your vehicle has to be registered in California. He said they are going to start aggressively pursuing these people. Just a wait and see, I guess.
