Your question is a bit confusing to me, but I'll give it a try. You say you are about to pay a $382.00 ticket and complete traffic school after I've paid the ticket. I think you may be confused about this. It is one alternative or the other, you either pay the ticket OR you attend traffic school, not both. My guess is the $382.00 is the amount of bail you posted promising to appear, that bail (if I am correct) will be refunded to you after you complete traffic school. You will however have to pay the school to attend traffic school, but it should be far less than $382.
As for the carpool violation, I doubt the court will let you do community service. They will likely offer you the opportunity to do jail time in lieu of the fine if you would like to do that. My guess is that is not an attractive option. If you are short on funds, the court will likely allow you to make payments until the entire fine is paid. I would suggest however you don't miss any or you'll have additional problems and possibly even a warrant out for failure to pay your fine. Good luck!
