I always learned that unless you're committed to the intersection (like stuck in the middle of it), you stop for the yellow. But then its been 30 years since I took my driver's test so maybe I should review it to see if it changed.
As I recall from my driver ed, back in the dark ages, the yellow was interpreted as "clear the intersection", which was further defined as "if you're not in it already, or so close that it would be unsafe to stop, then stay out of it; otherwise, get through it as quickly as it is safe to do so".
The other traffic thing that gripes me is the seemingly prevalent assumption that touching the turn signal long enough for the light to flash once while you're moving into the adjacent lane is somehow sufficient warning. People seem to have forgotten that the signal is not provided so you can announce what you have done, but to prepare the adjacent traffic for what you are planning to do, and that it is still your responsibility to make sure that your planned move is safe, before you make it.
