Can you drive a moped at age 14?

Yes you can drive a moped at the age of 14 years of age. 14 is the min age to drive a moped. And u are legal to drive a moped.

That all depends where you live. In NC it is 16, but you don't need a license at all, not even a permit. Just be 16 years old and wear a helmet. No license, no insurance, no permit, nothing but 16 and a helmet. Not even any tags/license plates/number plates. A moped can not be more than 50cc in NC and not do more than 30mph (although most will manage 45-50mph unless restricted), is not allowed to have any external gearchange mechanism (must be auto). The rules are different for each state.
