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.
It is generally easier to escape a car that is fully submerged underwater because there is equal pressure inside and outside the vehicle, making it easier to open the doors or break a window to escape. In a half-submerged car, the pressure difference between the inside and outside makes it more difficult to open the doors or windows.
There are many car engine damages that could occur to a vehicle from being submerged in water. Your car could short for example.
Junk it! It will be a money pit if you try to save it.
No, it is not. BUT: Starting a car with the exhaust submerged carries other risks. By implication there are other things submerged that could be damaged by water, such as the alternator, HVAC, or transmission. Also, the engine may not start if the starter cannot overcome the water pressure.
Really depends on the water and duration. I've had a vehicle get fully submerged in fresh water and be fine after a flush. In salt or brackish water, it wouldn't have turned out so well.
Only if the grating is submerged under a couple of inches of water.
Every component of the car will possibly need disassembled and checked for water damage.
When the glass is submerged in water, the air inside the glass is trapped and cannot escape. The pressure from the water prevents the air from escaping, creating an air pocket inside the glass.
The word submerged means it was under water instead of above the water.
I guess if you had the choice of where to submerge your vehicle, a lake would be the best place. Lakes are usually fresh water and relatively clean; relative to, say, flood waters. But fully or even partially submerged vehicles are NEVER the same after they are recovered, dried out, and cleaned up, especially if they were submerged in salt or filthy water. Some companies will "total" a car that has been immersed in salt or flood waters. When it has been submerged in fresh water, however, totaling depends upon the value of the car: if the remediation costs more than the car is worth, they will total it.
It would only be redundant if the context had already made it unambiguous that it was water. It is possible to be submerged under any liquid: for example french fries are cooked submerged under hot oil (they can't be cooked submerged under hot water).Yes, "submerged underwater" is redundant. Submerged under anything is redundant since the prefix "sub-" means "under." In most cases, the use of "submerged" alone is sufficient. In case there is some question about the substance something is submerged in (not necessarily liquid, not necessarily tangible), you might occasionally have use for "submerged in water."
A water lily is fully submerged an sends its leaves and flowers up to the surface.
