The first step is to compute how many points are involved with the New York State speeding ticket you have been given.
The following chart will help you figure this out:
1 - 10 mph over speed limit - 3 points
11 - 20 mph over speed limit - 4 points
21 - 30 mph over speed limit - 6 points
31 - 40 mph over speed limit (possible suspension) - 8 points
More than 40 mph over speed limit (possible suspension) - 11 points
Points are measured from the date of offense (even if you are convicted years later). So when adding the possible points for a newly issued speeding ticket. you must go back 18 months from the date of the new ticket and determine how many other points you have on your record. Also, three speeding convictions within 18 months will result in an automatic revocation in your driving privileges for 6 months.
The next step is to determine whether your case is returnable at a Traffic Violations Bureau (TVB) court or not. There are two, very different traffic court systems in New York State and, therefore, this determination is important for you to understand what you can and cannot do. If you are not within the TVB, then usually you can resolve the case by a plea deal.
The TVB courts cover any New York traffic ticket issued in New York City (Manhattan, Bronx, Brooklyn, Queens and Staten Island), western Suffolk, Buffalo and Rochester. A New York speeding ticket issued in any other place within New York State will not be a TVB court.
The reason this is an important inquiry is that TVB courts generally do not allow any type of deal-making or plea bargaining. Rather, you must either plead guilty or not guilty and, if you plead not guilty, you are given a hearing where you will either win or lose. In this "all or nothing" court, it really pays to retain an New York traffic lawyer to fight your case. That is, a New York traffic attorney who is experienced and knowledgeable in fighting speeding tickets at the TVB. Putting aside the emotions involved with fighting your own case, most motorists do not know how to listen carefully or cross examine. Rather, they basically ignore the officer's testimony, fail to ask any questions and, instead, just tell the judge their story. This incomplete approach is not recommended and is clearly not effective.
If you do fight your own TVB speeding ticket, listen carefully to the officer's testimony and even take notes. If the officer omits critical testimony (ex., date, time, location, direction, your ID information), then point this out to the judge after the officer rests. Similarly, if the officer gives testimony which is inconsistent with his other testimony or the information on the ticket, then likewise point this out to the judge.
For instance, I once was fighting a NYC speeding ticket when the officer testified that the motorist was proceeding east bound on the Long Island Expressway. The ticket, however, indicated W/B or west bound. After the officer rested, I showed the ticket to the judge who promptly dismissed the case.
Even without an omission or inconsistency, you should still ask thoughtful questions of the officer. For example, if your defense is that the officer pulled over the wrong car, then ask him where was he when he first saw your car, did he have to pass any other cars to apprehend your car, and how long did it take him or apprehend you. These types of questions build on your defense.
Also, ask to the see the officer's notes. Read them and determine whether his notes are consistent with his testimony. Any discrepancy should be pointed out to the judge. Also, do not be afraid to ask the officer to decipher illegible portions of his notes.
After your cross examination of the officer, it is time for you to offer your defense. Speak slowly and clearly. Hand up any evidence supporting your defense such as photos, witness statements or diagrams. Keep in mind that the judge hears many, many such cases and, therefore, you should not be repetitive or rambling about irrelevant information.
One last tip. Prior to fighting your case, watch the judge and how he handles other cases. Does he listen and take notes? Does he seem impatient or distracted? If you are concerned about whether you will get a fair hearing, ask for a new date. It is unlikely that you will get the same judge on the next assigned date.
