Tell me more about the roundabouts and exiting. Are there left exits from a roundabout? Don’t they all circulate anticlockwise (when viewed from above)?

There’s a new roundabout in my town and nobody knows how to signal. I see people enter with left signal flashing and then they’ll take the 3rd exit (out of 4 total). I’ve always entered without a signal, then exit right with a signal.

Also, I’ve seen many people go around backwards. That’s a fun surprise.
