Many times, persons question about the importance of bill boards, its utility and money spent is considered as waste. Questions are also raised about, does the reader / viewer is serious to understand and follow.
Apprehension were particularly w.r.t. posters, slogans, etc.
The way bill boards attract about products / entertainment visuals, the same way boards with preaching may not attract.
However, over a period of time, suddenly, a realization may come to the viewer by comparing his/her own experience and it strikes them for better.
For that particular moment to arrive, it can be immediate or it may take months/years together. Again, over a time, persons will forget. But, these displays act as a reminder.
Till such time, though it looks simple, the meaning is not understood.
We have to remember that slogans / proverbs are the outcome of somebody's experience or forethought. These are same as rules and regulations made after observing so many incidents / events.
Hence, we should give sufficient thought, have creativity to make attractive boards for personnel to see and understand at the earliest so that it helps them to follow for better, helps in day-to-day activities, develops attitude and safety culture.
