My jurisdiction is: California I was recently cited for making a U-Turn at an intersection where a No U-Turn sign is posted. The officer asked me if I had a "legal reason" for making the turn. The question seemed odd at the time but it wasn't until I drove away that I seemed to remember something from my 2007 CA drivers license test about this, something like; you could make such a turn if you did so in order to avoid blocking traffic... Well, I did make the turn to avoid blocking traffic and I think perhaps the officer even recognized that. Now as I consider challenging the ticket I cannot find any reference to this exception in the 2008 drivers handbook. Seems like it was a multiple choice question where that was the only answer that made any sense. Maybe it was on the actual test...am I dreaming? What would be a legal reason for make a U-Turn where a No U-Turn sign is posted? Thanks.
