A state police officer observed a car puttering along the highway at only 22 m.p.h. He turned on his lights and pulled the car over. Approaching the vehicle, he noticed that it contained five old ladies, two in the front seat and three in the back, and that all the old ladies were wide-eyed and white as ghosts.
The driver, obviously confused, said, "Officer, I don't understand. I was going exactly the speed limit. What's the problem?"
"Ma'am," the officer replied. "You weren't speeding, but you should know that driving slower than the speed limit can also be a danger to other drivers."
"Slower than the speed limit? I'm following the posted speed exactly!"
The officer, trying to contain a chuckle, explained "22" was the route number, not the speed limit. Embarrassed, the woman smiled and thanked him for pointing out her error.
Before letting her go, however, the officer asked, "Is everyone in the car okay? Those women seem awfully shaken, and they haven't made a peep this whole time."
"Oh, they'll be all right in a minute, officer. We just got off Route 119."
