Those red light cameras that discourage drivers from speeding through traffic signals are saving lives, according to a new study from the Insurance Institute for Highway Safety.

The report out Tuesday finds the enforcement cameras have reduced fatal crashes by 24 percent in 14 large cities. The devices were introduced between 1996 and 2004.

Some opponents argue there are cheaper alternatives to cameras, such as lengthening yellow lights or improving sight lines.
