You should retain an attorney to look into this for you. You can always call the officer, the location where speeding tickets are handled, or look at your driving record for a default on the ticket.
My response to your question is a generic response and should not be construed as controlling to your case. I can not effectively advise about your case without knowing all the facts. Additionally, my response does not create an attorney-client relationship. You can contact my office to schedule an appointment if you would like to have me represent you.
"I was accelerating from 45 to about 120 mph". The officer should have made the time to haul you off to jail. At 120 mph, you likely would have killed anyone you hit.
The officer likely sent you a ticket to your old address. Mail sent to the address you list with DOL is generally considered valid service for traffic tickets. You should check against your name whether you have a court case: http://dw.courts.wa.gov/index.cfm?fa=home.home .
Alternatively, the officer may have recommended criminal law charges against you. It may take the prosecutor a few days to review the recommendation.
You likely should start interviewing attorneys.
You might or might not receive a ticket, but regardless, you can also get charged with reckless driving, which is a gross misdemeanor.
Courts do check the DOL database if mail is returned to see if an address is current, and will sometimes resend the ticket to the updated address, but only if the ticket is returned to the court.
It's uncertain as to whether you will be cited. I would NOT call the officer.
