A police officer was patrolling the highway when he noticed a small car moving extremely slowly in the right lane.

It was going twenty miles per hour in a sixty-mile-per-hour zone.

Cars were honking, drivers were waving angrily, and one man in a truck looked like he was about to age five years from frustration.

The officer turned on his lights and pulled the car over.

Inside was a sweet-looking old lady with three other elderly women in the back seat. Strangely, the passengers looked terrified. Their faces were pale, their hands were gripping the seats, and one of them appeared to be whispering a prayer.

The officer walked up to the window.

“Good afternoon, ma’am.”

“Good afternoon, officer,” the old lady said cheerfully.

“Do you know why I stopped you?”

She smiled. “Was I driving too fast?”

The officer blinked.

“No, ma’am. Actually, you were driving much too slowly. You were going twenty miles per hour on the highway.”

The old lady frowned and pointed to a sign behind them.

“But officer, the sign said twenty.”

The officer looked back and tried not to laugh.

“Ma’am, that sign says Route 20. That’s the name of the road, not the speed limit.”

“Oh,” she said, looking embarrassed. “Well, that explains why everyone was in such a hurry.”

The officer smiled kindly.

“No harm done. Just make sure you follow the posted speed limit from now on.”

“I certainly will,” she said.

The officer was about to leave when he noticed the women in the back seat still looked absolutely frozen with fear.

He leaned down and asked, “Are your friends okay? They seem a little shaken.”

The old lady looked in the rearview mirror.

“Oh, they’re fine,” she said. “They’ve been quiet for a while, though.”

One of the women in the back slowly lifted her head and whispered:

“Ask her where we were before this road.”

The officer looked confused.

The old lady smiled proudly and said:

“Oh, before Route 20? We were on Route 145.”
