Final answer:
At a flashing yellow traffic signal, proceed with caution when turning left, yield to oncoming traffic and pedestrians, and be mindful of the posted speed limit to enhance safety.
Step-by-step explanation:
If you need to turn left at a flashing yellow traffic signal, it indicates that you are allowed to proceed with the turn but must yield to oncoming traffic and pedestrians. You should proceed with caution, make sure the intersection is clear, and be aware of the speed of oncoming vehicles, as many of them may be disregarding the speed limit. A traffic signal in this scenario also plays a critical role in pedestrian safety, allowing individuals to cross at appropriate times without having to dodge traffic. Additionally, a traffic signal can significantly reduce the number of accidents, as intersections with high accident rates and even fatalities suggest a strong need for traffic control.
