I think it is about time people realised the origin of all those ridiculous “baby on board” signs (and such inevitable copy-cat idiocies as “mother-in-law in boot” and “rottweiler on board”).
There was a tragic start to those signs.
Some years ago, there was a car crash in Canada. The police located adult and child members of a family trapped in the crashed car, rescued them and sent them to hospital to recover. The car was towed to an impounding yard, and the following day police discovered a baby’s body frozen to death but otherwise uninjured under one of the seats.
A campaign was then started in Canada to alert rescuers to the fact that there was a “baby on board”, which needed to be located in the event of a crash. If a baby is not on board, the sign is removed.
