3111 is Obedience to traffic control devices = no points ,fine only
3361 is Driving vehicle at safe speed = possible points added for this section plus a fine.
I doubt the D.J. give him 3111 for 23 mph over the speed limit. I bet the best they will do is let him plead guilty to 10 mph over which is reduced fines and points. Depends on the D.J.
