Things I Don't Understand - Episode 6: Left Turn Lights
Most traffic signals in my hometown allow left turns only when the left turn light is green. I live in a city nicknamed "Stoplight City" by truckers, so when I say "most traffic signals", I'm talking about a lot of traffic signals. I can't tell you how many times I sit at a red light while the traffic lanes for cars going straight remains green ... except there are no moving vehicles in sight. The only vehicles at the intersection are the ones in the left turn lane (with a red light), and the vehicles on the cross street. We all sit there waiting for the light to change.
I could easily, and just as importantly ... safely ... turn left, but if I did, I'd be breaking the law. Now keep in mind that before I sat at this light for five minutes, I had to turn left onto this very road not too far back ... with no outside help from anyone, man or machine. Where is the wisdom in that?
Some of the most dangerous intersections in the city allow you to turn left on a green arrow or a green light. If it's safe at the most dangerous of intersections, why is it so dangerous in safer ones?
The people who regulate traffic signals and roadways in this city probably have engineering degrees, and are a good reminder that even people who graduate in the bottom of their class can get a job with the government.
