There is no “Luxing” sign to tell the deer where to cross the road.
Let the driver know that this is where the deer often choose to cross the road.
Because deer are illiterate, even if they are literate, they may not bother to obey them. On the other hand, people are more likely to be killed by a deer than a shark.
A good slogan maker knows “what does it do” and “what does it do”. In this case, I hope the driver will be more careful.
Many times, all kinds of signs (metaphorical signs, not just physical signs) are simply yelling, making sign makers frustrated with things they can’t control. If you can’t influence something, why yell?
