For as long as many of us can remember, it's been red, yellow, green. Granted, in some places, you see a separate part of the light that shows protected greens or yellow or whatever. But generally, the 3-color combo is what we've known.
The one thing I can confirm that Lubbock drivers seem to be the worst at is parking. I don’t know why that is, maybe it’s a lack of parallel parking or sheer obliviousness, but there are some horrendous parking jobs I see on a daily basis.
