Where are the mandatory rules posted for using jack stands, etc.?

Seems to be considered one of those things that goes without saying. Sort of like always handle a firearm as if it was loaded.

Definitely always use jack stands. I also recommend putting the tires you (generally) have removed under the car to catch things if a jack stand should fail. I do this especially if I am crawling under the car. Tires and brakes, not so diligent, but always with jack stands.
