As an aside, I'd point out that almost no one understands vehicular right of way law in Virginia, because like many things, the basic law of right of way was designed by the Romans back when they were building roads across England, and survives in Virginia as one of those common law things that's not in the code. The basic law of right of way is, "first come, first served." Everything that's in the Code is an exception; you do have to know all the exceptions and how they interrelate, and that's a job in itself. The exceptions came when we started using motorized contraptions that can't be expected to stop on a dime and give you nine cents change. So don't make assumptions about who had or did not have the right of way. Btw, the cops almost always charge the wrong person, because they don't understand it, either.
Years ago, my history teacher pointed out that in VA nobody has the right of way: everybody in the statutes is yielding the right of way to somebody else. I filed it away under the "teacher said it so it must be true" category.
Then, a few years ago, I had the opportunity to do a little checking. Darned if the statutes I checked didn't all say who is supposed to be yielding the right of way, without saying the other guy had the right of way.
Except funerals. It came up in the news some months ago. Apparently funeral processions can apply for and receive a dispensation to have the right of way. I vaguely recall looking up the statute and saying, "well, I'll be darned", but I couldn't tell you what the statute said anymore.
And, if I recall, the statute about four-way-stops allows the driver on the right to proceed, but only when it is safe to do so. Got nothing to do with whether the guy on the left had the right or way or not, or whether the guy on the left yielded the right of way or not.
So, I'm less saying I've got contradictory info, than I'm kinda trying to integrate your comment about first-come, first-served with pre-existing observations. Are you basically saying second-come is generally supposed to be yielding the right of way to first-come? That's the only thing I can figure.
