State ID cards by the DMV
I've had parents in my family (mine, others) visiting from out of country get this. Comes in handy for insurance purposes and other places.
I don't know your state, but you can checkout the requirements. Its also useful if you aren't old enough to get a drivers license (I think your case).
Let us know if this works for you. Might come in handy for other people too. The card looks just like a drivers license, except it's just a state issued ID. Doubt anyone will have problems with it
