One reason this sign might be disobeyed is the lack of kerning in the T-A-Y sequence on the second line, and the Y-O pair in the third. Credited to NamelessCynic.

Lucas de Groot’s Calibri Bold was not meant to be condensed electronically like this. It could have been better on two lines at their natural widths, which would have had more impact, or a proper condensed typeface could have been chosen, to avoid the horizontals being thicker than the verticals.

There is no need to do an electronically condensed version of Arial Black, with terrible legibility thanks to the vertical strokes getting too thin, when there are perfectly good condensed typefaces out there.

If there is a chance of misinterpretation, don’t replace letters with symbols. People might just read the letters.

When doing important signs, make sure all letters are in the same, legible, readable typeface.

Don’t electronically condense your type to such an extent that the horizontals are thicker than the verticals when you can choose a condensed typeface. And leave enough room for all the letters.

Even a subtle electronic condensing does not help with legibility—either use a proper condensed typeface or have smaller type in its natural proportions.

When setting two blocks of text, make sure they are separated sufficiently so that there is no chance of ambiguity.

Plan your signage so that the letterspacing is more even across the entire line. Also referring this to our colleagues at Spelling Police.

Sometimes, it isn’t worth interrupting proper kerning just to have an unusual arrangement of letters, lest there be confusion about what one really means.
