Who has the right of way here?

When the light is solid green (no arrow), who has the right of way? The road they're turning onto has only one lane. I live in Alabama. I pass an intersection like this every day on the way home from work and never know what to do, so please let me know what you think!

BTW I took this drawing I found online from this article- https://www.thewisedrive.com/mixed-signals-who-should-yield/
