<human>: I'm in  the process of filing an appeal on a traffic court ruling of a speeding ticket and have a few questions about what a judge is legally allowed to do.
During the court session, the judge, in my cross-examination, rendered an objection as to why a question I was asking the citing officer was relevant to my case. Are judges allowed to render objections such as this or does this action show them acting as the prosecution?
exact quote, as per transcript: 
"MR. [KEWLIO250]: Did your [Officer XXXXXX] radar show 85 miles per hour before merging onto the freeway?   
THE COURT: I'm going to sustain my own objection. Why is that relevant?"
This was before I had started my testimony
Further on in the trial during my testimony, when presenting audio/video evidence in the form of dash cam footage, upon starting to present my view of the events, the judge abruptly stopped me, "THE COURT: Okay. I don't want to hear anything from you right now. Let me just review it. Okay?". 
Did this violate my right to present my case/evidence?

This is the first time I am dealing with appeals court and am a bit confused about what I can do to substantiate these claims. If anyone knows of any California appellate or supreme court rulings that may be applicable to this case please let me know

Can you give me a shortened version of the text?
<bot>: Can a judge render an objection on the prosecution's behalf? Can a judge prevent you from explaining evidence you have brought forth.
