You might also note that the signs they post
in the Sierra's when a storm is expected is that

not specify snow tires.

The signs don't; the pertinent law does. It reads "4WD with snow tires"
or chains. Law also specifies 4WD must carry chains in possession to
proceed. M&S rating is what they mean by "snow tires" BTW - almost all
modern tires are so rated.

It also specifies the 4WD must be engaged - lots of lawyerly flatlanders
drive their shiny spanking SUVs to the resorts but never learned how to
engage their part time 4WD. (part time 4WD are admittedly rare these AWD
days.) Then there's the folks who buy a humongous SUV with the 2WD
option - they pass by the DMV chain control guys pretending to be 4WD
and end up littered all over the shoulder, banged up.
