My question involves a speeding ticket from the State of: Washington State
May long weekend I recieved a speeding ticket, 85+ in a 70 mph zone. Upon inspection of the ticket I noticed that the vehicle information was incorrect. The ticket has me in a Washington State plate. I was visiting from British Columbia and was driving a vehicle with a BC plate, insurance and ownership documentation.
Is an incorrect licence plate a valid reason to contest a traffic infraction?
Does one contest the ticket as a whole or just the offences?
Can I contest this by mail from Canada?
Is contesting this matter in person recommended?
When contesting in person can I sill be charged for a speeding violation if asked under oath how fast I was travelling, independant of the wrong information?
My court date is set for late August and any advice would be greatly appreciated. I am not familiar with the legal system in Washington State, or BC for that matter, as this is my first traffic infraction. Thank you for your time. t.
