Re: Two Washington State Speeding Tickets
I would say that you "lucked out" so far. It would appear that -- for some unknown reason -- the Yakima court failed to properly file the deferral with the DOL. Thus, it was not on your record when you got the ticket in Snohomish. However, don't expect to be so lucky twice.
My guess is that when this latest ticket -- if you're convicted -- reaches the DOL, BOTH will be recorded on your driving record. As far as additional fines, I don't believe there will be any.
So, it is really in your best interest to contest this latest ticket. You seem to have a good handle on what to do (request discovery, check filing date). When you get your discovery information, look for holes (officer's location, moving or stationary radar, etc.). In my experience you are better off to NOT subpoena the officer, but you'll have to make that call yourself (if the information on the ticket seems complete, your only chance may be if the officer fails to show up).
The other thing you can try is to contact the Snohomish court again and ask what happens if you DON'T pay the deferral fee, but rather petition the court to reopen the case so you can plead guilty and just pay the fine. If they will allow you to do that, you might be able to get a deferral on this ticket (assuming the folks in Yakima haven't gotten their act together and updated the DOL records).
Oh, and slow down!
Where am I going? And why am I in this handbasket?
