This morning I took this picture, finding the
一人KY poster amusing:
QUESTION: What is the kanji before
In Gjiten I can't find it by combining the radicals of 止 and 残, nor by number of strokes (17?) plus 止 radical.
I guess the poster says "If you don't pay attention to your environment, you are at risk" (which the side text あなた自身があなたを守る says too), but knowing the kanji would confirm or infirm this hypothesis.
