What is wrong with this picture?

Think: adjective number agreement, and the lack of the requisite personal preposition "a", of course forgiving accents as they are not required on capital letters.
Ok, I know I am an irksome grammarian, but honestly, you would think that being a multi-billion dollar enterprise, whose home is situated in one of the most heavily hispanic-populated areas in the country, they could afford a good translation of safety notices and such. The funniest, or most ridiculous part is that in the very same tram there was another practically identical sign, with the error of adjective agreement ameliorated. Were they just shooting in the dark, hoping that one of them would be right?
