In some places, blue is used as a color, while others use orange as a color for their traffic lights. Some traffic lights use a kind of emoticon etched onto the lenses as a means to distinguish the colors. Since displaying only a color could be misinterpreted if you are color blind, there are traffic signals that also use shapes to distinguish the colors. Plus, different countries have used differing colors or shapes for their traffic signals. Given the at times unbearable on-hold at red lights I’ve endured, intuitively it sure seems like the grand total over a driving lifetime could be 6 months, or maybe it is more like 6 years where I live. I’ve not added-up my red-light waiting times to see whether this stat is applicable. One interesting stat that often is quoted suggests that we spend perhaps 6 months of our lives sitting at red lights. Admittedly, I try to get out of the red light abyss by purposely speeding up to try and catch the green light up ahead, but it often requires going so excessively above the speed limit that I cave in and drop my quest (though other audacious speeders near me seem to not care). There is nothing more frustrating than getting stuck at one red light after another, seemingly as though they are in cahoots with each other and wanting to keep me from getting to work on time. I am pretty sure that a disproportionate share seems to be on the streets that I use to get to work. Estimates are that there are 300,000 traffic signals across America.
