#6: Children on Board
School bus drivers need to be extra careful on the road, and the same goes for people driving in a school area. While the yellow school bus is pretty distinct, they usually have a bumper sticker indicating that this car is driving children, and other drivers need to be mindful of that.
Somehow, we get the impression this person isn’t the most careful driver on the road. They know a kid might fall out of the bus, so they have a bumper sticker saying, “Honk if a kid falls out.” At least they have self-awareness. We’d rather they be extra careful and make sure no kid falls out, but you can’t have everything.
