WHEN CAN I TURN LEFT?

I don't recall anything but 4 streets that meet at an intersection. It is not uncommon for FIVE streets to converge at one intersection here. It can be somewhat confusing to figure out who has the right of way. There have been several near misses at this particular intersection in our neighborhood. There have also been a lot of horns blasted from impatient drivers (can you imagine?) who think they can move forward, but they would actually be going through a red light. Case in point: You are stopped in the left lane at the intersection in road #3 and want to turn left. The driver behind you is blasting his horn at you. What should you do?


Help!
