#8 Car DIY: Escape a Sinking Car


In this Series of How-To posts, we’ll be covering knowing when to do something, how to do something and our own hack to try at your own risk. A big thanks to Tire Kickers, our sponsor and consultants on all things mechanical. They can be found on Facebook, or check out their auto health & safety advice.

(Note: this is the best information we could gather from our research and consulting our automotive advisors, but at the end of the day, our purpose is to entertain and inform. Don’t let us shame you into taking on something if you don’t feel qualified to do it. Trust your gut.)

Know When

The unlikely event of a water landing when driving a vehicle doesn’t mean it doesn’t happen. Unlike the duck and cover method of avoiding nuclear explosion you were tot in school, it actually can save your life to know how to escape a submerged vehicle. Assuming you were wearing your seatbelt so you weren’t knocked unconscious when your vehicle struck the surface of the water, you will have a little time before your car sinks—but not long.

The challenge is that the water pushing against the door will make it impossible to open the door. You’ll need to let the water in so that the pressure inside and out is equalized. Clearly, if you aren’t a professional free diver you’ll want to exit the car before it sinks too far, but the less air in the car the faster it will sink. Then there’s the whole needing to breathe. Bottom line, evacuate the vehicle swiftly without panicking.

Know How:

Roll a window down. Don’t freak out when it’s cold and you can’t do much until it’s full. Breathe while you still can. Then remove your seat belt. Visibility may be bad after the car is full of muddy water so make your preparations quickly. Still better to keep your seatbelt on until the rush of water is done—unless you need to get your kid out of a complicated car seat.

If you can’t roll down the window, because the water shorted your power systems, use a special device to break the window by striking it near a corner. It’s actually not easy to break a car window and there’s a good chance that you’re going to cut your hand. So plan on cutting your hand—it’s better than drowning.


If you don’t have one of the many devices we recommend below for smashing car windows, you can remove your headrest and use you metal legs.
