That being said, California does not recognize all the bikes and quads that are legally street registered in Arizona--that would be a definite no-go! I would assume that only the states that also street register ATVs and UTVs would allow a state to state transfer of such vehicles. I would believe that a tuk tuk would fit into this category, too--only registerable in a state like AZ, but only transferable to other states where 'oddball' vehicles can be street registered.
The only loophole would be someone who lived in Mexico and rode into California--but the tuk tuk would have to remain in Mexico (I am basing this on Mexican plated mini-trucks I have seen driving around in border cities of California).
That's so odd, since Cali allows bumper cars on the street.
