never EVER EVER plead Guilty EVER
do not ever just plead guilty with no further thought to a traffic offense, such as speeding, no seat belt, etc. NEVER.
First, try to sit thru a weekend Def. Driving course and the ticket will likely be dismissed once that is completed, depending on local jurisdiction
if that is not possible, the next step is enlist the help of a ticket lawyer to get the charge dismissed. So many people just plead and mail in the check, that the will likely just flat out dismiss it once he sees that it may be problematic to bring charges and a defense attorney is involved. It its a "41 in a 30" or a "no turn signal" he is gonna dismiss it. Period.
Technically, in Texas, the judge has to consent to dismiss a case, altho the prosecutor is the main player, he will bring in a stack of "for your dismissal your Honor" cases and the judge will eyeball them and rubber stamp them dismissed.
often, the case itself may not hold up in court anyway. If its a non-radar ticket, it is about 90% chance of dismissal.
in my area (Metroplex), the DA will not even pursue a DUI conviction if it is not on in-car video camera. Can the officer write a DUI? Yes. Will it get dismissed? (no video--->) Yes.
Also, "conviction" is accepted in legal circles to be a FINDING by a JUDGE or JURY that one is GUILY of a CRIME. It is the FINAL JUDGEMENT after a FINDING of GUILT.
So, if you do not fulfill the above criteria, you have not been convicted.
