Q&A - Are we legally required to use flashers at a controlled left hand turn intersection?
I often sit in a left hand turn controlled lane with 10 or more cars, all of us with our left turn indicators flashing away. We eventually drive through the left hand turn under the control of the left hand turn signal, still with our flashers clicking away.

I have a question about where to position my vehicle when making left turns at intersections with a traffic light. I have always entered the intersection (stopping somewhat before halfway through), then waited (with my signal on) to proceed safely and make the turn.
This case involves a collision that occurred in a school zone between vehicles parking at the curb. Mr. Ferguson had pulled over parallel to the curb and was preparing to back up and provide more room for others to park. Mr. Yang made a U turn from the other side of the street intending to pull in behind Mr. Ferguson and struck the Ferguson vehicle causing minor damage.
