Can you escape a submerged car in water?

Answer 1

Yes, first be calm, or as calm as you can be.

If the window is manual roll it down.

If windows are electric you will need to open the doors, this will be nearly impossible as long as the car is still filling up with water.

So while the water is coming in try to break one of the windows, and breath from the air bubble at the top of the passengers compartment., if not successful wait till the water has risen to the top of the door and you will be able to open it, it will take quite a bit more effort so be prepared.

There is a tool you can keep in your glove box that will help in an emergency like this, it is a drill guide.

it is a spring loaded device with a metal point to make a start hole for drilling, when pressed against a window it will cause it to break, that way you don't have to wait till the car fills up with water to get out.
