[1] Although theft often seems arbitrary, signs with unusual or amusing names tend to be stolen more frequently.
Sometimes considered to be a prank by the perpetrators, the theft is often costly and inconvenient for the municipality or agency that owns the sign, and it poses a danger to traffic.
In 1997, after a collision which killed three people, three young adults in the United States who stole a stop sign from the intersection where the crash occurred were found guilty of manslaughter.
[6][7] Many jurisdictions place stickers on street signs warning of the legal punishment for their theft.
Some cities (e.g. Toronto) use specially designed bolts to attach signs and prevent removal.
