There is a very steep uphill grade on an interstate near where I live. It also has a 3rd truck lane. It is VERY common to see trucks straining to get up that hill and going pretty slowly, and most of them have their 4 way flashers on.
I find that warning helpful, because it tells any oncoming drivers that the truck is going very slowly and to be cautious.
I can't tell you whether it is an illegal use in this situation in my state or not, but I see it happening on almost a daily basis, and I personally think it is a good safety practice.
Here's a link to every state and what they say about using the hazard warning flashers while driving. A few seem to say it is illegal while moving. Most say it is illegal except to indicate a traffic hazard (going very slowly up hill may be a reason, I would guess), and some just allow it for any reason.
