The language on a sign is important, but so is the visual design.
The words on a sign are important, but so is the shape of the sign.
In American English, 'visual design' in this case means the overall creative form the sign takes, including any information it is trying to convey. On the other hand, the 'shape' of the sign refers more to its geometric form, such as whether the particular sign is a circle, square, rectangle, hexagon, or triangle. In the rural U.S., if you find yourself driving down a country road, you might notice an unusual and rather improvised design feature of road signs: bullet holes.
