The City of McKinney has announced that it is implementing a new left-turn traffic signal display that will include flashing yellow arrows.
Flashing yellow arrows are being added to traffic signals to make intersections safer, reduce wait times and provide greater signal timing flexibility, the city said.
Crews began installing signals with flashing yellow arrows this week.
At intersections with this new configuration, the flashing yellow arrow means left turns are permitted, but drivers must first yield to oncoming traffic and pedestrians -- and then turn with caution because oncoming traffic has a green light.
A steady yellow arrow means the left-turn signal is about to change to red, and drivers should prepare to stop or prepare to complete the left turn if the car is within the intersection.
The green arrow still means it is safe to make a protected left turn.
