Thankfully, you can understand the meaning of a road sign by simply learning about what colors, shapes, and symbols are used.
In order to help drivers process road sign meanings faster, the U. Department of Transportation DOT moved towards the use of symbols rather than words. Symbols are far better at conveying different safety messages, they are easier to recognize and understand, and they are fairly universal. The use of symbols is quickly becoming the standard for traffic control devices throughout the world. The DOT also has a standard for the color and shape of particular signs.
