I *mostly* agree.
Around here, the law doesn't say you have to use a climbing lane
unless you're slow-moving. That's unlike a typical multilane road,
where you are required to keep to the right except to pass. The
posting is different, too: "KEEP RIGHT EXCEPT TO PASS" for an ordinary
multilane road as opposed to "SLOW MOVING TRAFFIC KEEP RIGHT" for a
climbing lane. They're often striped differently, too:
is an example. (Uphill is to the west.) The resolution on the orthos
isn't quite good enough to show that the rightmost lane is separated
by a double broken line, not just a single one, but you can see that
it looks heavier in the imagery. That stretch is also signed that
HGV's, buses and trailers are forbidden in the leftmost lane.
We also have the occasional spot like
There, we have an extra lane on the northbound side for the purpose of
getting by when the way is blocked by left-turning traffic. When the
way is clear, it's normal and expected to proceed through the
intersection on the main lane. By contrast, the extra lane on the
southbound side is striped and signed as a dedicated turning lane.
I'd still ordinarily just use the 'lanes' tags and possible turn
restrictions. (If I troubled to tag traffic lanes. Ordinarily, I
don't. I have other fish to fry.)
