Time for the US to nationalise all things vehicle.
If they did that it would increase emissions a lot. They also have already tried to do that but courts ruled that a) California could still have its own emissions standards because California invented emissions standards as far as the US is concerned and b) other states which previously chose to follow California's emissions standards before the US had them can continue to follow California's.
Of course there's no guarantee that the conservative-owned SCOTUS won't change that again.
Driver licensing (including for trucks, busses etc).
The standards for operation of commercial trucks, busses etc. are already set by the federal government. States implement them but are not in charge of them, except for filling in the blanks left by incompetent and inadequate federal law as usual. Maybe you should educate yourself about the status quo before agitating for changes to it.
