A flawed camera system to catch red-light runners is costing Los Angeles County at least $500,000 in refunds over 2,500 invalid traffic tickets. The Los Angeles Times says that officials cannot even begin to guess the final price tag in the case of the missing half-second at an East Los Angeles intersection.
The camera should have been set to photograph motorists who entered the intersection more than three seconds after the signal turned yellow. But a retiree who set up a Web site on the issue– http://www.highwayrobbery.net — determined that the light actually stayed yellow for 3.5 seconds.
It turned out that more than half of 5,063 tickets issued over the cameras’ 42 months of operation were invalid – the drivers had been “caught” while the light was still amber.
