> 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, use an emergency safety tool, like a spring loaded emergency hammer or an object from inside the vehicle to break the glass.
