Woman woke up to every parent’s worst nightmare. Now, this grieving mother is sounding the alarm about a deadly winter habit

A viral video is warning people about a dangerous winter habit that many drivers think is safe. The video shares a sad story where a daughter died from carbon monoxide poisoning after she and her mother took a nap in an idling car. The woman who posted the warning wants drivers to be more careful before sitting in their cars to warm up this winter.

According to Motor1, the woman behind the warning, known online as Ms. Andrist, posted a 34-second video just before extremely cold weather hit. She clearly explained how easily things can go wrong and warned viewers that parking in an open space doesn’t always keep you safe when you’re warming up your car.

Ms. Andrist shared a terrible incident on TikTok that proves her point. The tragedy involved a mother and daughter who were napping in their car. She said, “When the mom woke up the daughter had passed away.” This happened even though they were not in their garage but sitting in a completely open parking lot.

Carbon monoxide danger exists even in open spaces

Carbon monoxide is often called the “silent killer” because it has no color and no smell. You can’t detect it without special equipment. While most people know running a car in a closed garage is dangerous, fewer people know that carbon monoxide poisoning can happen even in open areas. More than 400 Americans die from accidental carbon monoxide poisoning every year, not counting fire-related deaths, and over 100,000 people visit emergency rooms for related problems each year.

Experts say the main cause of outdoor poisoning is snow and ice blocking the exhaust pipe. When the tailpipe is clogged, the deadly gas can’t escape and goes back into the car. This danger was shown a few years ago when a mother and her two children died in a running car in New Jersey while the father was clearing snow nearby. Many drivers ignore warning signs for too long, which can lead to tragic outcomes.

Ms. Andrist’s advice is simple and important: “If you’re warming up in your car, roll the windows down every couple minutes just so you know you get some air circulating.” She also suggested cracking the windows every 10 to 15 minutes if you plan on staying still for a while.

Official winter driving safety guidelines support this warning and tell drivers to always make sure their exhaust pipe is clear of any snow or ice before starting the engine. They suggest running the car only occasionally, just long enough to stay warm. You should also have a mechanic check your exhaust system every year. Regular maintenance is crucial, especially since common driving habits can damage vehicles without people realizing it.

Ms. Andrist’s video quickly went viral, getting over 814,000 views and many worried comments. Many people were surprised the danger existed outside of closed garages. One commenter reminded others, “Also make sure snow is not covering your exhaust pipe.” Another viewer suggested, “just use a carbon monoxide alarm.” A third person pointed out, “Also carbon monoxide poisoning is scentless so you wouldn’t even know what is going on.”
