Context Fail: Flipped

As in:
A tractor-trailer has flipped on its side forcing police to close the two south bound lanes of Maitland Ave.
To me, a "flip" describes a end-over-end motion which sweeps at minimum 180 degrees. 270 degrees is more like it.

Compare: if I flip onto my back, it implies I went face-first, my feet go over my head, and I end up on my back. If I go over backwards and end up on my back, to me it just implies a 90 degree change in orientation -- in other words, I just fell over backwards.

While I'm sure that someone, somewhere has "flipped" a tractor trailer onto its side, using the terms "flopped" or "fell over" is probably far more descriptive.
