Greetings all,

The OP reminds me of a problem that someone recently explained to me. Their spouse is colorblind and they are easily confused by horizontally oriented traffic signal lights. As long as the light is vertical, they remember that the top light is the red light. But when they approach a horizontal signal light (we have several in my area) they are not sure which is the red and which is the green light.

So, if you ever need to cross at an intersection with a horizontal signal light---be extra careful.

Kind regards, RoadLight
