Tickets and traffic court

hello all...what do you know about traffic violations, tickets (moving and perking) and about traffic court in general...
my personal question is...if a cop pulls you over and gives you a ticket and it has the wrong liscence number one...yes...one did that to me part of my number is 0003 he wrote 0006
thusly the ticket would logically be void would it not? but the legal system in the usa is really messed up and makes little sence so i wanna know from some ppl who know (or atleast think they know it well enough) to tell me what i should do...
my second question has to do with the same ticket WTF is "improper lane usage" i think i didnt signal when i lane changed or something but thats so pathetic if i have to go to court over that -,-

a cop pulled me over and wrote the wrong year and make of my vehicle on the ticket i took it to court told the judge he must have clocked a vehicle other than mine and stopped me instead of the other vehicle in error the judge ask the cop if it was my van and did he recognize me, cop said yes judge said guilty! good luck but you probably are screwed

ah...well that sux...i did get one thing...the cop said i was speeding in a 40mph zone and i drove on that street later that week and the speed limit is 45...i doubt itll help me any...cops are...well pigs sometimes...the judges trust them more that us obviously but i havent met a single honest cop for a long while...i think my uncle is one of the only ones i know...<< >> i know cops that STEAL (or atleast supposedly steal,ive only caught one)...and i really dun even care about the fact that the police force is corrupt...cuz what you gonna do TELL THE COPS...-,-
