The number of smartphone addicts is getting higher.
They use smartphones while eating, walking, even crossing the street.
We combine traffic signs with smartphone addicts to say that "Don't use the phone when crossing the street. "It is very dangerous to people who ignore surrounding when they use smartphones".
