But not always!

While I agree with you, our signs do say "Falling"!

Our UXO, or "Live bombs" sign, depending on the sign it's on, is

I think that moved away from "bomb" because other things (artillery shells,
grenades, rockets etc) can all blow up & kill you?

Yes, they are permanent features & relatively common out here, with a
"very" complicated warning sign!

A few more that I've just thought of:

Tilting truck: This sign warns that trucks may tip over when driving around
the curve of the road or when making a turn.

Emergency vehicles: give you early warning that emergency vehicles may
suddenly drive in or out of their entrance onto the road.
https://en.wikipedia.org/wiki/File:Australia_road_sign_W5-SA70.svg

Grid: to warn that you are approaching a cattle grid - we already have a
tag for grids, do we also need a sign to warn that they're coming up?
