A policeman was on patrol when he came upon a line of cars stopped at a light with horns blasting. The light directing that lane of traffic was green. He pulled out of line and stopped alongside of the first car in line to see what the problem was.
The car was driven by an elderly woman. He asked her why she was stopped when the light was green.
She said, "Oh, because I'm on my way to my sister's house which is that way." and she pointed to the right.
The motorcycle cop said, "Well go ahead! The light is green."
The elderly woman responded with, "Yes I know, but the sign under the light says 'RIGHT TURN ON RED.'.
