Slow Driver

[ScubaLatt]

Sitting on the side of the highway waiting to catch speeding drivers, a police officer sees a car puttering along at 22 m.p.h.. He says to himself, "This driver is just as dangerous as a speeder!"
So he puts on his lights and pulls the driver over.
Approaching the car, he notices there are five old ladies in the vehicle -- two in the front seat and three in the back -- all but the driver are wide-eyed and white as ghosts.
The driver, obviously confused, says to him, "Officer, I don't understand, I was doing exactly the speed limit! What seems to be the problem?"
"Ma'am," the officer replies, "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?", say the surprised driver. "No, sir. I was doing the speed limit exactly -- 22 miles an hour," the old woman says a bit proudly.
The police officer, trying to contain a chuckle, explains to her that 22 is the highway number, not the speed limit.
A bit embarrassed, the woman grins and thanks the officer for pointing out her error.
"Before I let you go, Ma'am,", says the officer, "I have to ask: Is everyone in this car OK? These women seem awfully shaken, and they haven't made a peep this whole time," says the officer.
"Oh, they'll be alright in a minute officer," replied the driver. "We just got off Highway 105."
