My husband is a sheriff's deputy and he said that every State is different, each one has varied laws/penalties and more importantly, every Judge is different - so anything could go no matter what anyone on this thread suggests.
But, with that being said, here is a case he witnessed:
Driver was a younger kid with a learner's permit (they're supposed to have an adult with them while driving).  It was 2:30am and the driver was driving himself and 5 other friends in an SUV.
On court day the Judge gave the young driver 50 hours of community service and a year suspension on his license.
The only tips my husband had was:
Be humble.  Dress for court.   Show up on time for your court day.  Remember your manners (yes sir/ma'am, etc).  Speak for yourself - don't try and have your parents bail you out - it shows responsibility that you're owning up to the mistake. 
Expect the worst and hope for the best.  Maybe you'll just get community service or driving school.  
Regardless, I think we all here can say we're on your side and wish you the best!!
