The other day I encountered this situation. I was gonna turn left, and the road was almost clear, except for one car was approaching and that guy changed to right lane about 50m away from the intersection. At this time, his right turn signal was still on. It seemed safe for me, so I took the left turn. But the lady in the car following me was not so lucky. She followed me and took the left turn, then I heard a hard braking behind me from the approaching car. Apparently, that guy was just going straight rather than taking a turn.
No accident happened, but it's scared though. The lesson is, always remember that some people often forget to turn off their signals.
