I was pulled over this morning on the way to work for turning right on red where it was posted as prohibited. After I committed the offense, I turned into my parking lot at work and the officer waved me over. The officer pointed out the sign and wrote a citation.
My question is that the officer was located on private property (where I work) while monitoring the intersection. Since he witnessed me turning, then stopped me inside that very same parking lot that is private property, do I have any way to challenge the citation?
This is in Columbus, Ohio.
