Fighting Speeding Tickets without a lawyer really makes sense if the goal is too save money, if you lose a court appearance many times you are going to pay more than if you didn't fight it, and with the cost of US lawyers the cost of a loss is that much more, so if you are going to fight a ticket doing it yourself is the way to go we feel. You of course will pay more in car insurance if you lose so don't forget to factor that in as well it might actually be better to pay more and use a lawyer, if your insurance will cost that much more with a loss.
See if you can negotiate before the trail, sometimes if you have some good facts you might get the DA to deal and assign you to traffic school, which will be a loss but it will not affect your insurance, which for many is the ultimate goal as the ticket will hurt but the increase in the car insurance will cost a lot more over the long term.
The one of the easiest ways to beat a ticket is too plead not guilty and show up in court. Many times the cop that wrote the ticket will not be there which is in many jurisdictions a automatic dismissal. Another strategy is to prolong as far out as you can through asking for continuances or to reschedule your appearance. The further out you can be from the event the harder it is going to be for the officer to remember the specifics.
In US Law it is about proving your facts. I repeat in US Law it is about proving your facts, if you can not refute the prosecutor and the officer in a speeding case then you are going to lose, there are no real defenses if you are guilty unless you can find fault in the evidence against you. One of the things that you can do is write down all the facts about the day and circumstances like weather, traffic what you were wearing, do you have any irregularities on your car that would stand out. were there any passengers, what you want to present to the court is that the officer really does not remember the circumstances. If you have a witness have them write down everything as well.
What means was the infraction found? Radar, Pacing or officers judgment. You can be found quilt of speeding even if you were under the speeding limit posted if the officer that wrote the ticket can paint a compelling scenario to the judge a good example would be driving in limited visibility in fog or maybe trough a fire's smoke. If you can show evidence or offer eye witness that the visibility was not as bad as the law officer presents that might be enough for a judge to side with you and dismiss the case or rule you not guilty.
When was the radar last calibrated and where there any obstructions between you and the radar gun.
Pacing how far did the officer follow you to establish the speed, How far away was he flowing you from and when was the officers car checked to see if the speedometer was correct. Obviously if you are 20 miles over there is going to be less of a reason for a judge to rule in your favor but if it was 5 to 10 miles over the judge might rule in your favor if you can put some doubt into his or her mind that the information used was off or tainted by distances or things like curves or obstructions.
