How old are you supposed to be to drive a gas scooter?

That all depends on the size of an engine. If it is under 50cc (in Michigan at least) you must be at least 15 and get a moped license which costs about 8 bucks, and you have to register the moped and put a sticker ont he back that costs 15 bucks. If it is OVER 50cc you need a driver's license and a moped endorsement.

If it IS under 50cc AND you have a driver's license, you're good to go. Also, if you get a driver's license after you get a moped license, you have to give up the moped license, but you can still legally ride it
