A state trooper noticed a car driving down the highway very slowly. His radar clocked the vehicle at about 21 mph. The trooper, worried that the driver might be in trouble, turned on his siren and brought the slow-moving car to a stop.

The driver was an elderly man with thick glasses. In the back seat sat two old ladies, both pale and trembling with fright. “What’s wrong, officer?” asked the driver. “I was driving the speed limit. It was on that-there sign, back yonder a ways.”

The trooper realized what had likely happened. “Sir, that wasn’t the speed limit sign, that was the route number. The speed limit on state highways is 55 miles per hour. You’re on Highway 22.”

“Gosh, Officer,” the man said with a nod. “Sorry about that, and thanks for settin’ me straight. Am I in trouble?”

The trooper looked into the back seat. “No sir, I’m just concerned for you and the safety of your passengers. Are these ladies all right?”

“Oh, those are my sisters,” said the driver. “They’ll be fine. We just got off, uh, Highway 125.”
