What if your vehicle breaks through?
If your car or truck plunges through the ice, the best time to escape is before it sinks, not after. It will stay afloat a few seconds to several minutes depending on the airtightness of the vehicle.
- While the car is still afloat, the best escape hatches are the side windows since the doors may be held shut by the water pressure. If the windows are blocked, try to push the windshield or rear window out with your feet or shoulder.
- A vehicle with its engine in the front will sink at a steep angle and may land on its roof if the water is 15 feet or deeper. As the car starts its final plunge to the bottom, water rapidly displaces the remaining air. An air bubble can stay in a submerged vehicle, but it is unlikely that it would remain by the time the car hits the bottom.
- When the car is completely filled, the doors may be a little easier to open unless they are blocked by mud and silt. Remember too, chances are that the car will be upside‑down at this point! Add darkness and near freezing water, and your chances of escape have greatly diminished. This underscores the necessity of getting out of the car before it starts to sink!
