The highway¹ patrolman sported a car driving dangerously slow on a much-traveled freeway². He pulled it over and found the driver to be an elderly³ lady with four other older women as passengers.

"Lady," said the officer, "your slow driving is almost as dangerous as speeders. You need to try to keep the speed limit⁴."

"But I always keep the speed limit," replied the lady. "I was doing the speed limit when you stopped me."

The officer asked, "What do you think the limit is on this road?"

The dear old lady said, "I just a moment ago saw the sign, U.S. Highway 22."

"But lady," warned⁵ the officer, "that is the highway number, not the speed limit"

The lady was very apologetic（道歉的） and, of course, no ticket was given. The officer noticed that all the passengers seemed pale and had a frightened look in their eyes. As he turned to leave the car, wondering if his presence⁶ had been the problem, he turned again and said to the driver, "Ma'am, are you sure all your passengers are OK?"

"Oh, they will be in a few moments," she said, "we just turned off Highway 120."
