What are the self-rescue methods when a motor vehicle accidentally falls into water?

[MaliaAnn]

Here is an introduction to the self-rescue methods when a motor vehicle accidentally falls into water: 1. When the vehicle door cannot be opened after the motor vehicle accidentally falls into water, the self-rescue method is to break the glass to allow water to enter the cabin. This balances the pressure inside and outside the cabin, making it easier to open the driver's door. Once the door is opened, you can enter the water and easily swim to the surface, avoiding danger. 2. When a motor vehicle accidentally falls into water, the water pressure is greater than the air pressure inside the cabin. Therefore, the driver's door cannot be opened. Only when the pressure inside and outside the cabin is equal can the door be opened. The only method at this time is to use a hammer to break the glass and allow water to enter. Hence, it is advisable to keep such tools handy in the cabin for emergencies.
