Follow the classic Starman explanation, red light stop, green light go, yellow light go really really fast.[1] In my state you are permitted to enter an intersection if the light is solid yellow which is used to indicate it till soon be red. We also have recently seen an expansion of the yellow left turn signals that can be yellow while your main lane is red, meaning you can make a left turn as long as oncoming traffic permits. Those actually made things much better at many intersections. still when I learned to drive I was told if I was turning and the first car in line that I should be in the intersection ready to turn which could mean completing the turn on red https://youtu.be/6NEFYCaKakE https://youtu.be/6NEFYCaKakE
