My question involves a traffic ticket from the state of: Washington

I received a speeding ticket in July (40 in a 25), which also had a second infraction of no insurance (did not have the card with me). I've already taken care of the proof of insurance and filed that with the court. I've filed for discovery and received that just yesterday. The police statement doesn't have any holes in it that pop out at me right away. There are some discrepancies between the ticket and his report. Namely the city the infraction took place and the time, however I know that wouldn't be grounds for dismissal by the judge. The SMD certificate is within the 2 year calibration period, so I cannot use an out of date certification as grounds for dismissal either. I am wondering if anyone has any insight into defense for this ticket that I can use. Any help would be much appreciated. Thanks in advance.
