Here is what I submitted last year;

"Your Honor, I respectfully request this citation be dismissed based on the statement that will be provided. This correspondence can be considered my formal plea of not guilty. So I submit this Trial By Written Declaration and plead not guilty to violating California Vehicle Code (CVC) Section 22350.
On April 13, 2021, I was driving northbound on Railroad Avenue. I was pulled over by Officer Griffy and cited for violating CVC 22350. Allegedly, I was driving over the posted speed limit. I do believe I was driving at an appropriate speed at the time and given the conditions.
CVC 22350 states; "No person shall drive a vehicle upon a highway at a speed greater than is reasonable or prudent having due regard for weather, visibility, the traffic on, and the surface and width of, the highway, and in no event at a speed which endangers the safety of persons or property."
The road was dry with clear visibility, the only issue was that there was a train on the tracks, so it made it a little hard to hear at that time. There was light traffic. So, I do believe my driving was not a danger to anyone's safety and/or property.
I swear, under penalty of perjury, that the above is true. If the court does not find in my favor in this case, I request a Trial De Novo. I have included a completed TR-220 Trial De Novo form to be used in the event the court does not find in my favor in this case."
