I would add one thing...if you're coming up to an intersection that you think might be a 3-way or 4-way stop, look for an actual indication of a stop sign (either an actual sign or a line on the road) and if there isn't one, DON'T STOP.

The intersection where 14 South and 15 split in Hardwick is horrible for this. People coming up the hill don't have to stop, but probably one in four cars does anyway. And it creates a traffic nightmare. Partly because if the road is even a tiny bit slippery, it can be impossible to get going again on that hill if you have to stop (I know this because I once had to do a 3-point turn in the middle of the road and go back down the hill because we had an early snowstorm and I didn't have my winter tires on and could not go forward...one of those days when they predicted "flurries" and we ended up with 4").

It's also a huge pain for trucks to get going again on that hill if they have to stop. That said, despite the signs on the two directions that do have to stop telling them that cross traffic doesn't stop, people will pull out in front of cars that are coming up the hill all the time. So you do have to watch when you're coming up the hill, but you definitely don't need to stop...

There are multiple intersections like this in Vermont and they're all nightmares...
