Often "No Turn on Red" signs are very difficult to see. The city of Ann Arbor does not use its brain when posting them. They are blocked by other signs, trees, snow etc. The law recommends up to 3 visible "No Turn on Red" signs at an intersection. Also, there must be more than just one sign at the far side of the intersection. These problems with posting signs are what got me to show up to court in the first place.
