Thank goodness you're all right.
That's the important thing.
If you have rental car coverage on your insurance, you should be able to get a rental. You may be stuck for the young driver surcharge, though, and your parents might have to co-sign. Or you might want to see if your garage has loaner cars - again, though, one of your parents may have to co-sign.
I take it from your description of the accident, that you mean it's "illegal" to pass a car on the right that's waiting to make a left turn? That ain't what they taught *me* in driver's ed! If she was signaling a left turn, you were entitled to pass her on the right. Otherwise, all traffic would come to a complete standstill! If you got a ticket - fight it.
