Couldn’t a state law decide what vehicle one can use on their road, instead of what one can buy?

This is what Cali does with their emissions standards but it also seems like people who care worked around it by just registering their cars in other states. And I say this with all the love in the world, if there's any group of people who will massively inconvenience themselves to spite the government it's truck owners.
