What does a continuously flashing road signal light indicate ahead?

[DelViolet]

Yellow light flashing indicates that you need to slow down and observe the road conditions at the intersection ahead, as it is a hazardous section. Introduction: Traffic signal lights are lights that direct traffic operation. Classification: Traffic signal lights are divided into motor vehicle signal lights, non-motor vehicle signal lights, pedestrian crossing signal lights, direction indicator lights (arrow signal lights), lane signal lights, flashing warning signal lights, and road-railway level crossing signal lights. Light colors: In the earliest times, there were only red and green colors. Later, after improvements, a yellow light was added. The red light means stop, the yellow light means prepare, and the green light means go.
