The corner of 56th and Sligh Avenue is one of over 90 Bay Area intersections with a light box displaying four left hand arrows-- red, green, solid yellow and flashing yellow.

"We found there were a lot of crashes happening where people were turning left and didn't know whether they had the right of way or not," said Kristen Carson of the Florida Department of Transportation.

Carson says the relatively new traffic signals are helping to prevent collisions between cars going straight and those turning left.

"National studies had shown this flashing yellow arrow guides people to know they have to yield. They don't have the right away. They have to yield to oncoming cars," said Carson

The solid yellow arrow means the light's about to turn red.  Most people have figured it out, but there has been a learning curve.

Accidents around the country have been blamed on driver confusion over the flashing yellow arrows.  A few communities have had them taken out.   

But national research indicates the new system gets more cars through intersections  and reduces accidents.
