Have you driven by the Largo Post Office lately and seen the new traffic light with the flashing yellow arrow at the intersection of Eighth Avenue and Seminole Boulevard?

The new flashing yellow arrow lets drivers turn left after yielding to oncoming traffic and pedestrians.

The new flashing yellow arrows are based on a national study by the Federal Highway Administration. The study showed the new light is a low-cost way to prevent crashes and get more traffic through an intersection safer, according to a news release. 

The study showed "drivers are less likely to make left-turn mistakes when guided by the flashing yellow arrows," according to a news release. 

The state believes this is the first traffic signal of its type to be installed in Largo. It has been testing one in St. Petersburg, according to the City of St. Petersburg's website. 

The new light was installed as a part of recent drainage and road repair improvements around the intersection of Eighth Avenue and Seminole Boulevard.

• Red arrow means stop and remain stopped. No left turns allowed.
• Yellow arrow means prepare to stop or complete your left turn if you are in an intersection
• Flashing yellow arrow means left turns allowed. Yield to oncoming traffic and pedestrians. The oncoming traffic has the green light.
