California was the first state to legalize right-on-red in 1939, with some western states joining throughout the 1950s and 1960s.[2][3][4] Right-on-red was legalized nationwide in an attempt to save fuel during the 1973 oil crisis.[5]

Grew up and learned to drive in SoCal, so right-on-red is the norm for me. But you are supposed to come to a full stop, not the infamous California rolling stop.
