Also Truck tags have NOTHING to do with height laws, thats a old myth. Only ones that Help with height Laws are FARM USE, meaning is not driven on the road that much.
What he said, it depends on how you registered your "truck" and how much weight you said you haul or tow. You can get a semi and put standard plates on it but legally you cant haul it rated capacity like that. Get over a certain weight and you need a special license.
Truck tags do help with bumper laws (a little) because certain GVWR allows slightly higher bumpers.
