On the way home from work yesterday, I was behind a vehicle with one of those 'Baby on board' signs suckered onto the rear window. (It was a 4WD too, so that gave it two black marks in my book.) Those signs annoy me because of what they imply, to me anyway. However I have no idea why people really use them, and wondered what others thought, so here's a little poll.
[Edit] The first explanation is the most nearly correct according to the Snopes site. To quote them, "there's a child in the car, so drive carefully". Drivers should drive carefully regardless of who's in the other vehicles. What am I, chopped liver? Yes, potentially.
What do people who use 'Baby on board' signs mean by them?
BTW one of my favourite Farside cartoons shows a fly driving a car with a 'Maggot on board' sign in its rear window. What sign should Vilakins put in her Liberator (all right, her Integra with the number plate LIBR8R)?
