I recently received a speeding ticket for 76 in a 60 in Snohomish County, WA. This is my second of two tickets on my record, the first of which I received only a few months ago (and naively didn't fight).
I recently requested discovery and the officer's information indicates that I blew a BAC (exact number included) that was below the legal limit (true) and that I had admitted to speeding (false). It also indicates that my speed was gauged using a laser, which is very surprising given what had happened:
I was driving the speed limit when my exit was approaching and I needed to change lanes. The car in the exit lane wasn't budging, so I sped up to pass it and enter the exit lane. Soon after a black vehicle sped up to get directly behind my car (1' or less) and continued to follow me. I had no idea who was behind me and didn't want my brand new car to be wrecked by some tailgater, so I sped up. ~20 seconds later, the blue and red lights went on... surprise! The cop had been dangerously close behind me, yet wasn't even pacing to gauge my speed.
Anyway, my court date is in the near future and I wonder what my chances are for fighting this. Thoughts? Any insight would be greatly appreciated.
