Do you have a least favorite traffic light? I’d be willing to bet that most people who drive daily in Iowa have a light at which they hate getting stuck. I don’t think this problem is specific to Iowa either but there is nothing worse than approaching a traffic light you know takes forever to turn green, and as you’re 100 yards away, you watch the light change from yellow to red. Usually, the busier the intersection, and depending on if you’re making a left turn or going straight, the longer you’ll have to wait.
