On May 19th in Shanwei, Guangdong, a video captured a peculiar phenomenon on the road as a large vehicle was driving, revealing a sudden misty curtain ahead, which indicated the imminent arrival of a torrential downpour.

Within seconds, the weather transitioned from overcast to heavy rainfall, causing the driver to activate the windshield wipers; however, visibility of the road outside the window remained challenging.

The unusual occurrence has sparked curiosity and discussions among online communities, leading Chinese netizens to engage in debates about the appropriateness of using fog lights or hazard lights during stormy conditions, and whether it is best to activate both simultaneously.
