Does the green light you see at the intersection indicate a collision-free left turn?

Why?

The ordinary green signal on the S-1 traffic light allows you to pass the signal, but does not guarantee a conflict-free left turn. When turning left, you must give way to oncoming vehicles travelling straight ahead or turning right.
