differences about road signs between Japan and America

There are many differences between driving of Japan and America. I will introduce four differences about road signs. First, in Japan road guide signs are green in a superhighway and blue in an ordinary road, but in America they are mainly green. In other words, Japan’s road guide signs have two colors and America’s have one. Second, in Japan signs are displayed by symbol on the contrary, in America they are indicated by phrase. For example, American signs describe “one way”. However, Japanese ones display an arrow signpost. Third, Japanese isn’t strict a parking so much but American is strict a parking. In America if you leave car even one second in no-parking area you will pay a fine. Fourth, in Japan you check whether the trains come or not in front of a crossing, but in America you should not check. It may cause a rear-end accident. So when we drive foreign countries we must understand traffic rules of foreign countries.
