A study by the Insurance Institute for Highway Safety (IIHS) looked at 14 cities using red light cameras and found that the combined per capita rate of fatal red light accidents decreased by 35 percent. On the flip side, The Federal Highway Administration and Virginia Transportation Research Council found that red light cameras probably caused more rear-end crashes.

"If you stop for a yellow light, you are blameless," CarInsurance.com consumer analyst Penny Gusner says. "Even if you get hit from behind, it's their fault, not yours."

So how do you stay safe when approaching an intersection and the light is yellow?
Maria A. Wojtczak, owner of
, offers this advice: "Use the broken white or yellow lines as indicators. Each line represents 10 mph. If you only have two lines before entering the intersection and are going 40 mph, you have reached the point of no return and must continue through the light. If there are four or five lines before the intersection you have plenty of time to make a safe stop."
Experts also remind drivers to avoid changing lanes in an intersection -- which is also illegal.
