I am from Alaska with an excellent driving record, and was in CA when I was cited for "failure to yield at yield sign for approaching vehicles." I was westbound on a two-way street, and the citing officer was eastbound (non-emergency) on the same street. We were both turning onto the same ramp to I-880 NB. As I turned right, I had a yield sign on the island to my left, but I was ahead of him and noticed that he was still turning and so I proceeded forward merging ahead of him in a manner I felt was safe. He felt I should have waited for him, and cited me for failure to yield. In no way did I intentionally fail to yield, and with no accident and no witnesses, I feel the citation is unwarranted and possibly initiated because I did not give him the extra measure of distance he's used to.
