After all these replies, I think I am more confused.
One or more replies indicated a pedestrian always has the option to cross against a light.
I grew up and learned to drive in Minneapolis, got my license in 1966. Back then it was simple, if, as a pedestrian, you wanted to cross a street, you pushed the button and waited for the Don’t walk light to change to Walk , the light turned green, you still looked both ways before crossing. Simple, why did the states, including Florida, come up with flashing amber means stop for pedestrians? We have had pedestrians killed, traffic got the flashing amber, pedestrians no longer are taught to look left and right before crossing.
