		Exactly, it's legit to use them on the motorway or dual carridgeway (when moving) to warn of slowing traffic ahead etc. And a bloody good idea to do so, it's one of those very sketchy situations I look out for, then filter in to the safety of the bunched traffic soon as I can.
Perhaps not so much of an issue at filtering speeds on motorway, but watch out for people seeing only the left/right hazard and reading it as a turn signal.
