Flashing Yellow Arrow

In an effort to minimize the safety concerns with left turn movements, a national study was conducted to determine the most effective way to alert drivers when to yield to oncoming traffic. This study showed the Flashing Yellow Arrow (FYA) was safer and more effective than a simple circular green ball that is typically used. As such, cities across the country are installing FYAs, and the City of Billings is no exception. With the installation of FYAs, traffic will be able to perform the left turn movement more safely and with less confusion.
