Flashing Yellow Arrow 

The City of Frisco is installing new traffic signal displays with a Flashing Yellow Arrow (FYA) to improve safety, to reduce traffic delays and to provide traffic engineers flexibility during variable traffic volumes. The FYA left-turn signal replaces the circular green indication for left turns at selected intersections and helps drivers make better choices about turning left when oncoming traffic is clear.

Safer intersections
National studies show drivers are less likely to make an unsafe decision when turning left using a FYA signal instead of the circular green traffic indication only.

Less delay
Drivers have more opportunities to make a left turn with a FYA than with a traditional circular green left-turn indication. This reduces wait times at intersections and helps keep more traffic moving.

Signal timing flexibility 
Traffic engineers have more options to handle variable traffic volumes. As a result, drivers may not see the flashing yellow arrow or steady green arrow every time. The signals can be programmed to better serve the traffic demands at the intersection depending on the time of day.

Guide to FYA Traffic Signals


     Steady red arrow indicates drivers turning left must stop and cannot enter the intersection.

Steady yellow arrow indicates the signal is about to turn red. Do not enter the intersection if the vehicle can safely stop. 

Flashing yellow arrow (FYA) indicates drivers may proceed making a left turn with caution when there is an adequate gap. (Drivers are yielding to oncoming traffic and pedestrians who have a green light and the right-of-way.)

Steady green arrow indicates drivers turning left have the right-of-way at the intersection. 

The Federal Highway Administration approved flashing yellow arrow (FYA) signals for widespread use in 2009. The 2011 Texas Manual on Uniform Traffic Control Devices (TMUTCD), released in December 2011, requires  the city to install FYA left-turn displays at signals with protected/permitted left-turns.
