Let's scotch this idea of smv straightaway. Whereas PSV, HGV and LGV are
well-established abbreviations, at least in UK English, I've never come
across slow-moving vehicles referred to as SMVs - this seems to have
been made up on the fly in this thread. We don't really like
abbreviations in OSM anyway. As slow-moving_vehicle is a bit of a
mouthful, I'd suggest slow_vehicle as a reasonable tag to use. Or crawler.

Okay, I guess the consensus here is that, even though I dislike it, I
must use the lanes approach. In my original tagging, I had invented a
new category of service road, service=slow_vehicle_turnout, but
perhaps an abbreviated form of slow_moving_vehicle would be more
consistent and easier in the end. In the example provided by
SelfishSeahorse, he uses smv:lanes:forward=|designated (as well as its
counterpart in lanes:forward) and that seems consistent with other
abbreviated tags, like hov and hgv so I'll use that terminology in my
tagging. Perhaps someone of you would like to add the smv abbreviation
and description to the Wiki.
Thanks for the input and discussion,

before that you would be correct (and usually as a stopgap between
striping, places where this is still the case is highlighted by
signage, but this is getting to be rare as most plsces have had
long enough to require a repaint if not a repave since then).
The states have had considerable leeway in how they mark their own
highways (the Federal government has control only on the highways that
it funds). New York has used a single solid white line to mean 'lane
crossing discouraged but not prohibited' for the 45 years that I've
been driving here. Prohibited lane crossings have, for at least that
long, been set off by double lines or by partial-barrier lines with
the solid line toward the lane that must not be departed from.
I seem to recall that the meaning of a single solid yellow line has
varied from 'crossing discouraged', to 'crossing forbidden but left
turns permitted', to 'crossing prohibited'. The current drivers'
manual states that they have the same regulatory effect as a double
yellow line. (Left turns across a double yellow are permitted only
when they can be accomplished without impeding traffic in either
direction and only into private driveways, entrances and alleys.) The
only single yellow center lines I've seen in the last couple of
decades have been on private roads, where they mean, 'the owner was
too cheap to shell out for enough paint for standard markings.'
