How to NOT design something

By and large, traffic signs are supposed to be clear to drivers. Countless potholes, heavy traffic, turning difficulties, and other inconveniences plague drivers everywhere. When traffic signs don't make any sense to the driver, however, things can get frustrating and potentially life threatening to people on the road. Scenarios like this show that proper design is vital to both a company's reputation and to other people as well. Thus, it is clear that something must be done to handle this problem, preferably by replacing the confusing traffic signs with ones that actually make sense.
