Are there US national laws for "motor-driven cycles"?

Question

i am planning a cross country trip. i did it one other time in a hurry, this time i want to take my time. i want to do this on a scooter or "motor-driven cycle". is there a national law that i can go by as far as license and size scooter? or would i have to follow the laws of every state that i would travel in?

also, is there any online reasorce that has information on scooter laws? i have tried different DOT sites.. none of which are clear in the way they explain. or at least clear to me...

Answer 1

There is no national vehicle code. You will need to check the laws in each state you will travel in.

Search for <state> motor vehicle code

Answer 2

i believe you must be over 16 and have your basic driver's license
