At night, faced with a broken-down vehicle up ahead, a driver urgently waved a warning triangle and their phone to stop a potential secondary crash.
On March 19, the YouTube channel 'Han Moon Chul TV' posted a video titled 'Episode 26,704: Preventing a secondary crash by vigorously waving a warning triangle and a phone'.
The footage shows a driver spotting a disabled car on a dark road, then signaling other vehicles by waving the phone’s light and a warning triangle. Using both the triangle and the phone, they tried to head off any additional collisions on the unlit roadway—an on-the-spot response that’s now reminding viewers just how crucial swift action is in an emergency.
One comment read, "In-car fire extinguishers are now mandatory—signal batons or flare beacons should be mandatory too. Do you really think swinging those around makes you visible on a dark night?" Another added, "Still, that driver did a decent job responding… most people just switch on the hazards, or if they use hand signals at all, they only wave behind the stopped car. Going forward, the law should require people to carry more emergency gear in their vehicles."
