With the summer in full swing, it is very tempting have a water bottle in your car as you drive.  I’m sure by now almost everyone has heard experts warn you about the dangers of leaving a water bottle in your car.  But what if I told you that keeping a water bottle in your vehicle has far more danger to you than you thought? Could your water bottle actually cause a fire to start in the car? The answer, unfortunately,

[could be] yes!

During the summer, we are all aware that our cars become a “hot-box”.  The sun not only makes your windshield extremely hot and untouchable, but it also accelerates the temperature in your vehicle in a matter of minutes.  Now imagine that you ran into a store to shop, leaving your water bottle on or near your seat.  It may seem like a frivolous thing to even worry about, but there is a real hidden danger that could happen as a result of leaving your water bottle in your car.  Firefighters are warning people that keeping water bottles in your car, and in direct sunlight, can potentially cause your car to go up in flames!  As the sun beams through your windshield, it also goes through your water bottle.  The water acts like a magnifying glass by focusing the light (and the heat) onto a single point.  Much like when kids hold a magnifying glass over an ant hill, sunlight gets magnified by the water bottle reaching over 250 degrees within seconds.  This focus of light ends up burning a small hole in your seat or interior, and if you are not around to catch this, it will result in a fire.

Luckily, Firefighters say that the risk of a sustainable fire occurring is low.  However, that doesn’t mean that you should throw caution to the wind. The best way to prevent this type of accident occurring is to take your bottle with you whenever you exit your vehicle.  If you need to keep water in your car, be sure to keep them in an area where sunlight cannot reach the plastic, such as under your seat or in your trunk.  You can also opt to use reusable water bottles that are not clear, and are free of BPA’s, which as we have all heard, can cause cancer.

So go out and enjoy your remaining summer weather, keep hydrated, and make sure to keep any liquid in your vehicles away from sunlight.

All the Best,

Lynda Drew
