I started thinking about reading in terms of traffic signs and street signs. Although there are some signs that are always a particular color and shape, like the "STOP" sign, not all maintain such individual qualities. Take, for example, the white rectangular signs we see while driving. These signs could read anything from "NO TURN ON RED" to "RIGHT TURN ONLY." Both of which mean two very different things. Since signs like these are not accompanied by any sort of picture, there is no way for one to differentiate between them, unless they are able to read. However, there could be an argument of whether or not one should be allowed to drive if he or she is unable to read.
Regarding traffic signs that contain only words, maybe we could assign a picture for each, like many other traffic signs. For example, for the "NO TURN ON RED" sign, a symbol consisting of a red circle, an "=" sign and a turn symbol circled with a slash through it (like the existing sign) could mean the same as "NO TURN ON RED." The "RIGHT TURN ONLY" sign, however, is not as problematic because there are often "right turn" symbols painted on the road or illustrated on a sign, as well.
While coming up with the previous idea, which I am not sure is that much of an issue, I also came up with the issue of streetlights that go out. Regarding this issue, I thought about the night lights that one might have throughout one's house that come on by themselves when it is dark in that area. Similarly, we could create streetlights that do the same. These particular night lights that I am talking about do not contain a bulb on any sort--they are LED lights. Therefore, they do not burn out. If we were to create streetlights the same way these night lights are made, there would be no issue of streetlights burning out. An out streetlight could be very dangerous, especially in an area where there aren't many in the first place. With this creation, that danger would be eliminated.
