It sort of depends. Mainly, if it's a 50cc engine, the answer is no, because they are unable to go fast enough to be safe in highway traffic. Also, since 50cc scooter (and mopeds) are typically limited by law to a maximum of 30mph (but can usually go somewhat faster), they are not allowed on anything but secondary streets.
Most states require any vehicle to be able to go whatever the posted speed limit is. If the speed limit is faster than 35MPH (the maximum speed for most 50cc scooters), they are illegal on the highway.
Some states are more specific: at the entrances to Interstates (and some other highways), there are signs at on-ramps to the highways listing a number of things not permitted on the highway, one of which is "Scooters less then 10hp".
Scooters with engine sizes of 150cc or greater, of course, typically have cruising speeds of 50mph or greater, and therefore would be allowed on highways.

If the moped is street legal and requires a license plate you cannot drive it at 13 years old on any public streets or highway.
There's no such thing as a 250cc moped. A moped is a 50cc scooter with a top speed of 30mph restricted.
An electric moped will not be able to go 40 MPH.
NO! Mopeds generally are 50cc or less. Some states allow highway travel with a minimum of 150cc which is suicidal, unless it can maintain 70mph. Personally I would go no less than 250cc for highway riding, and more like 400cc for long distance touring with or without a passenger and with the ability to pass comfortably at highway speeds.
my 50 cc moped can go 30-35 at top speed
at a scooter shop
You can drive a moped at the age of 14. The age for a moped in the U.K. is 16. Spain and Italy is 14
Dont ride the basterd
That is a matter of personal opinion and is also influenced to some extent on the use you intend for it. If you like to go off road then a Trails or Enduro Moped would be best. If you care more about speed then a Sports moped would suit you best and for economy a commuter moped or scooter.
go down hill
No, you can't. Not in the US. You can't drive a 49cc moped on the highway in any state I'm familiar with.
No not at all just go to you DMV to get info.
