A man was driving from Surry to Washington. Hearing a strange noise from the back of the car, he naturally got out to take a look. He examined the wheels carefully, but since he found nothing wrong, he continued on his way. The noise began almost immediately and now it was louder than ever. Quickly turning his head to look back, the man saw what appeared to be a great black cloud following the car. When he stopped at a gas station farther on, he was told that a queen bee must hide somewhere in his car because his car was covered with bees.
The poor driver telephoned the police and explained what had happened. The police decided that the best way to deal with the situation would be to call a local beekeeper. In a short time, the beekeeper arrived. He found the unwelcome passenger hidden near the rear axle of the car. Very grateful to the driver for the unexpected gift, the beekeeper took the queen and her thousands of followers home in a large box. Equally grateful, the driver drove away at last free from the "black cloud" which had hung over his car.

Why did the driver stop his car the first time().
