A man was driving down the road. He passed a traffic camera and saw it flash.

Astounded that he had been caught speeding when he was doing the speed limit, he turned around and, going even slower, he passed by the camera.

Again, he saw it flash. He couldn't believe it! So he turned and, going a snail's pace, he passed the camera.

AGAIN, he saw the camera flash. He guessed it must have a fault, and home he went.

Four weeks later he received 3 traffic fines in the mail, all for not wearing a seatbelt.
