City records show less than half of the more than 230,000 drivers caught by cameras running red lights in Fort Worth during the last fiscal year actually paid the $75 ticket.

The Fort Worth Star-Telegram reports the non-payments were sent out for collections but because the tickets are civil violations, they won't be reported to a credit bureau. They also don't show up on driving records, which means the Fort Worth tickets don't impact a driver's insurance rates.

Backers of the cameras, which produced $2.4 million for the city, say they promote safety.

Kelly Canon, who led a successful recent effort to stop the camera use in nearby Arlington, says the devices are unconstitutional. She's pushing to put the question of red-light cameras before Fort Worth voters next November.
