My initial reaction to the image with the caution sign was confusion, I've never a sign like that before. It also made me wonder why such a sign even exists. The silhouette figures in the image look distraught, they are running away as fast as they can, as if they were being chased. The way the mom is holding the little girl's arm as if trying to get her to run faster, and the girl trying, but failing to catch up with her mother. The caution sign is meant to warn people about families or pedestrians running through the road. The warning is apparent because it is directly implied, there is a clear picture of it. I can locate an appeal to the emotions because there is a child in flight in the image which may appeal to the nurturing emotion many
