What does a continuously flashing yellow light indicate?

[OBlakely]

A continuously flashing yellow light indicates the need to slow down and proceed with caution. Legally, a yellow light serves as a warning. A flashing yellow light alone means that the intersection is not controlled by traffic signals, and vehicles passing through must observe the surroundings to decide whether to stop or proceed. Such signals are typically installed at intersections with low traffic volume or during off-peak hours like nighttime. Below are relevant explanations: 1. Traffic signals consist of red, green, and yellow lights. A red light prohibits passage, a green light permits passage, and a yellow light serves as a warning. 2. According to regulations, when a yellow light is on, vehicles that have already crossed the stop line may continue to proceed, while vehicles that have not crossed the stop line must stop. Proceeding under such circumstances constitutes a traffic violation for disobeying traffic signal instructions and may be subject to penalties.
