traffic light

Red-light cameras reduce fatal car crashes, according to a new study from the Insurance Institute for Highway Safety. In the cities studied, deaths involving red-light violations dropped by an average of nearly 25%. But don't expect the cameras to bring in city revenue.

Motorists, beware. Some cities have been caught shortening the duration of yellow lights to make more revenue off tickets for running red lights, the National Motorists Association says. At least six cities including Dallas and Chattanooga, Tenn. have engaged in the practice in recent years, the organization says.
