Much products liability litigation is directed at whether a product warning was reasonably clear in explaining the actual risk of the product. A subsidiary argument involves pictorial warnings. Pictorial warnings have the benefit of being understood by persons who read in different languages or who are illiterate. Their downside is that they often are unclear because it is difficult to capture most product warnings in a simple picture or symbol.
But I think everyone would agree that the graphic pictorial warning on this vehicle with a rotating-shaft device clearly indicates this is a risk a reasonable person would avoid.
