no lo also means that your are "asking the mercy of the court". Then it is up to the judge to accept it or not.

I have a ton of speeding tickets, and always pay them instead of court, if you can. I got nailed on PIB in Doraville for like 72 in a 55, and that ticket was $450...
My last ticket was 109 in a 55. My wife went to school with the guy that pulled us over, and I almost got out of it but he had already called for backup. The sarge was "letting me off easy, by not taking me straight to jail". I went to court and paid about 1500 for everything, 6 months probation, 40 hours community service, and 10 days in jail.
And I was 27 in a $45k truck, so that kid that did 124 on Sugarloaf is funny...
