Why Can't Car Doors Be Opened After Submerging in Water?

[LaElena]

Because except for convertibles, most cars on the market have excellent sealing. The glass and sealing strips isolate the inside of the car from the outside. When a car submerges in water, due to its good sealing, water cannot quickly flow into the car. Under the effect of water, there will be a pressure difference between the inside and outside of the car. The water pressure will tightly "fix" the car door, making it impossible to open easily at this time. Below is relevant information: Unfasten the seatbelt: The seatbelt is the first thing to think of, but it is often forgotten in panic. Especially when there are children in the car, unfasten the children starting from the oldest, as they can help the other children. If the seatbelt cannot be unfastened, it can be cut with a sharp object. Break the window: If the window cannot be opened or is only half-opened, it must be broken. Use tools (such as an escape hammer to strike the four corners of the glass), feet, sharp objects, or even a woman's high heels to break the window. It may seem counterintuitive to let water into the car, but the sooner the window is opened, the sooner you can escape through it.
