In Brazil, the “No Parking” sign is a common symbol that everyone understands. In it, we see the

letter E (for “estacionar”- park), crossed by a red line inside a circle of the same color. For our

consciousness campaign, we made identical signs, but using all of the other letters and we put them

in the same places that No Parking signs are found: on the street and on the gates of houses

(owners use them to prevent drivers from blocking entrance to their garages). These unusual signs

attracted the immediate attention of motorists and pedestrians alike, getting them to stop and

read our message: while driving, every letter is prohibited.
