At least two motorists in Johannesburg, South Africa, have been ticketed by speed cameras for traveling more than 80 kilometers per hour on the M1 North highway. The problem is that the speed limit on the road is 100 kilometers per hour—faster than they were driving. The police insist the cameras are set correctly, and the tickets were issued because of an administrative mistake. But Ronnie Frank, the motorist who discovered the problem, says it's possible that many other motorists just paid their tickets without checking to see if they were actually driving over the speed limit. "If this is happening on the M1, it could be happening on all the highways and everywhere that cameras are used," said Ana Cox, a reporter for The Star newspaper, who was also incorrectly ticketed.
