Im from WA State and just got my 1st speeding ticket doing 75mph on 60mph zone the thing is I thought it was still 70mph zone not familliar with the freeway a little bit dark (7:58pm) and Im so tired driving from Vancouver BC. I was in the carpool the road ahead is a little uphill theres a vehicle in front of me and theres few following me before we got to uphill the vehicle in front of me change lane the same time the vehicles following me change lane too living me alone in the carpool doing 75mph. The officer told me that i was doing 77mph weird i think his SMD isnt working really well. So do you think i can plead not guilty? What should I do? Can i just keep on delaying the proceding? will it work?
