Double the speed limit in a school zone could be grounds for reckless driving ticket. Thats an 8 pointer. I am sure you are required to show up due to the speed and the zone. If you have a clean record they will often offer you a reduced fine and point total if you pay right there.
I wouldn't recommend a lawyer unless you are facing the loss of your license and losing your job. But what were you doing going 50 in a school zone. Kids are retards and you could have ended up in a lot worse shape. Sorry for the lecture, stepping off my soap box.
