A highway patrol officer stopped an elderly woman for driving 10 mph on the highway. As he walked up to the old woman’s car, he noticed that there were 3 other old people who looked very frightened and stiff. He leaned over to the old woman’s window and noticed that she was as calm as could be. “Do you know why I stopped you, ma’am?” “No, I don’t,” she replied sweetly.

“You were driving ten miles an hour on the highway. That is a serious hazard to other drivers.” The policeman could not stop looking at the three frightened passengers.

The little old lady pointed to a nearby sign. “Isn’t the speed limit 10?” The policeman looked at the sign and laughed. “Ma’am, that sign tells you what highway you are on. Interstate 10.”

The little old lady burst out laughing. “Oh, I’m sorry!” The officer decided it was an honest mistake and wanted to let her go. But his curiosity got the better of him. “May I ask why your passengers are so frightened?” The little old lady laughed again. “Probably because I just got off Interstate 175.”
