Right on Red
In the United States a red light can be treated as a Stop Sign when you are making a right turn, meaning you dont' have to wait for the light to turn green in order to turn. This is not the case though in the boroughs of New York City, due to the high volume of pedestrians. There are, however, a few exceptions when the sign above is posted. But I guess by the time someone reads the sign upside down the light will already have turned green.
