Sitting by the side of the road one day, on the lookout for speeding drivers,a police officer spotted a car puttering along at 20mph.
He thought to himself: “That driver is just as dangerous as a speeder!” So he turned on his lights and pulled the driver over.
Approaching the car, he noticed that the four passengers were all old ladies, and all wide-eyed and white as ghosts.
The driver, also a very elderly lady, was upset at being stopped.
“Officer. I don’t understand, I was doing exactly the speed limit!”
“Madam” the officer replied patiently, you weren’t doing the speed limit you were driving at 20 miles an hour.
That can be dangerous to other drivers.
“But it says A20 on the sign over there-and so I was doing it!” she protested.
“But that is the road number, not the speed limit.”
“Well I never! That explains a lot,” said the old lady in evident relief.
“Before I let you go, madam, I have to ask, is everyone in this car okay? Your passengers seem awfully shaken.”
” Oh, they’ll be alright in a minute,officer. We just got off the A164.”
