As you probably know if you are an American

This reminds me of https://xkcd.com/2501/

I don't think it's presumptuous to assume that most Americans understand what road markings mean. (Insert joke about the drivers in your least-favorite state.)

My state's driver manual:

  • Explicitly mentions double solid white lines and broken white lines.

  • Doesn't mention single solid white lines (outside of the separate context of shoulders—MUTCD § 3B.09), but they're pretty rare, outside of (1) construction zones, where they typically are accompanied by "stay in lane" signs anyway, and (2) intersection approaches, where changing lanes is forbidden under state law, as mentioned in a different part of the driver manual.

  • Doesn't mention dotted white lines, but IMO an attentive motorist (or new motorist and former passenger) should have noticed the growing prevalence of these lines over the past decade.

I agree with you, although I've never seen double white lines and thought any solid line was "do not cross". Still, I know that white lines separate traffic going the same way and yellow lines separate traffic going the opposite way, and the significance of dashed versus dotted lines.

I don't know if I've ever seen double white lines outside of an airport runway.

I recently just went on an 11.5 hour road trip.

The only time I can recall seeing them is on the tolled express lane of I-85 in Georgia.
