I received a speeding ticket and the police report states I was traveling NB when in fact I was traveling SB. What can I do?

Respectfully, this type of defect is unlikely to get the ticket dismissed. Obviously, it can be used to try to get a better plea offer or to impeach the credibility of the officer if you were to take the case to trial, but it is unlikely to convince a prosecutor to simply dismiss. Good luck.

If your testimony is contradictory and is supported well and the officer is not present during your contested hearing you may be able to prevent the preponderance of the evidence from being in the state's favor.
I would reccomend having a attorney who practices in the local area where you got ticket review the case.
In Washington, the standard for traffic infractions is preponderance of evidence and the judge will assign weight to each parties testimony, affidavits and other supporting evidence.

Good Luck

I do not practice in your state but I have won many traffic infraction hearings because the officer could not attend. I do not know how the officer can prove his case if he does not show up in court. Please go back to Aurora Ave.N and see if there is a place where the officers pull off the road so they can monitor traffic and see if the location gives you some idea of evidence which could contradict the info on the ticket.
Good luck
