All redesigned and new signals will include flashing yellow arrows for the appropriate vehicle movements.

A flashing yellow arrow means left turns are permitted, but commuters must first yield to oncoming traffic and pedestrians and then proceed with caution.

The flashing yellow arrow does not replace the solid yellow arrow and its meaning, a red arrow still restricts the left turn movements.

Drivers should always remember that a flashing yellow arrow means turn with caution.

How does it help?

According to the Florida Department of Transportation, left-turn crashes are some of the most common types of crashes, after rear-end crashes, with some studies showing they represent almost 20 percent of all car accidents. A national study demonstrated drivers had fewer crashes with the flashing yellow left-turn arrow than with the traditional, yielding left-turn indication.
