Can You Open the Car Door Underwater?

[OAlex]

If a vehicle accidentally falls into water, it is difficult to open the car door for a period of time after the vehicle is submerged. Here is relevant information: 1. Reason: When the vehicle first enters the water, there is a large amount of air inside the car, while the outside is water. The pressure difference between the inside and outside is significant, making it difficult to open the door directly, thus preventing a quick escape. Only after a substantial amount of water enters the car, reducing the air and equalizing the pressure difference, does it become easier to open the door. 2. Precautions: A car will not sink immediately after falling into water, allowing a window of one and a half minutes or even two minutes to escape through the door or window before sinking. Even if the car sinks to the bottom, there are ways to escape, as it may take up to half an hour for the cabin to fill with water. The exact time depends on whether the windows are open, the body is sealed, and the depth of the water. The deeper the car sinks, the greater the water pressure, and the faster the cabin fills with water.
