I’m pretty sure it’s a: flashing yellow lights. I’m sorry if this was wrong.
The correct answer is A) a flashing yellow light.
When you see a flashing yellow light, slow down and pay special attention to conditions around the intersection as you pass through it.
When you are driving and you are about to cross an intersection, be very careful because the street can have transit in both ways. So you slow down and carefully watch for signals. If there is a flashing yellow light pay attention because something happens. Maybe there are men at work. So you carefully drive, see both sides of the street and cross the intersection.
