Entering a Plea of Guilty
By a plea of "Guilty," you admit that you committed the act charged in the complaint(s), that the act is prohibited by law, and that you have no legal defense for your act.
If you were involved in an incident where someone was injured at the time of the alleged offense, your plea of "Guilty" could be used later in a civil suit for damages as an admission by you that you were at fault or were the party responsible for the injury.
