What action is required when encountering a flashing yellow light at an intersection?

Answer: B — Proceed with caution after checking the intersection

When encountering a flashing yellow light at an intersection, the proper action is to proceed with caution after checking the intersection. A flashing yellow light alerts drivers that they should be alert and prepared to stop, as other vehicles or pedestrians may be present. It indicates that they can continue moving through the intersection but must do so safely and with awareness of their surroundings. This approach allows drivers to assess the situation, determine if it's safe to proceed, and allows for the potential presence of cross traffic or pedestrians who may have the right of way. It emphasizes the need for vigilance rather than rushing or stopping abruptly, which could lead to confusion or accidents, especially if there are vehicles behind the driver.
