There would be a "Delayed Green" sign posted on the arm holding the traffic light. The delay would be something like 5-seconds, allowing a couple cars to turn left before the opposing traffic started moving. Obviously, this was not something for real high traffic. I used to see this in my hometown on streets near downtown that had no left turn lane. But, it's been thirty years since I've seen one.
In my hometown (in central Massachusetts), there's a "delayed green" at the main intersection (with the sign and everything).
