This depends on the laws of the state issuing the ticket and the offense. Assuming this is a moving violation, there is usually a box on the ticket maked "Court Appearance Required" or something similar to indicate that you cannot simply mail in the fine like with a parking ticket. If you hire a lawyer, generally, he/she will write to the court, enter a not guilty plea for you, request discovery and ask for an adjournment of the first court date. The court date will most likely be adjourned since the court sees that there is a lawyer and it is now a contested case. If you don't hire a lawyer, you probably have to go to court and verbally enter a not guilty plea. If you plead not guilty, the court will give you a new date for the trial.
In traffic court you can plead in the following manner: Guilty - Not Guilty - No Contest - or (in some traffic courts) Guilty With An Explanation.
No.
pay a fine and go to court
Depending on the charge you can usually plead guilty and send in a fine.
You don't plead guilty "on a traffic ticket" unless you post your fine, request a court date, and then fail to show up at the traffic court hearing.You are then automatically adjudged guilty by reason of your failing to appear to defend yourself. If you DO go to court you may plead not guilty to the offense, and the judge will grant a hearing in which you and the officer will give testimony, and then the judge will render his verdict. If you have previously pled guilty, or forfeited your fine, in court you will have to file a motion to re-open the case.
Guilty
You don't...usually you have make an appearance in Court if you are attempting to plead not-guilty to a traffic violation. Once you plead not guilty then you will be scheduled for a trial. This will allow for you (defendant) to show proof the traffic citation was in error as a mistake of the issuing law enforcement officer. Be prepared to be cross examined by the Traffic Court judge, as it takes more time & energy to fight a citation than it does to pay the fine and/or traffic school. At least in California.
A traffic court handles traffic ticket cases. If a person has pleaded not guilty they appear in front a judge and plead their case. The judge takes into account the evidence of the police to and then make a decision.
I don't think you can appeal after a guilty plea.
Yes
If I understand the question correctly - it sounds like the officer cut you a break by giving you a lesser charge. You know you were speeding 45 mph over the limit! 'Man up' and plead guilty, and if it's your first traffic offense, ask if you can attend traffic school instead of getting points.
Overwhelmingly obvious proof (evidence) of the offense would lead a guilty defendant to just go ahead and plead to the charge.
