Why Can't You Open the Window When a Car Falls into Water?

Because opening the window can cause water to flood into the cabin, leading to the risk of drowning. Here are the relevant details: 1. Car Window: The car window is an essential part of the entire vehicle body, designed to meet the needs of interior lighting, ventilation, and visibility for drivers and passengers. Depending on the installation position of the glass, car windows include: front and rear windshields, side windows, and door windows. The design, structure, and quality of the windows significantly impact the driver's visibility, passenger comfort, exterior aesthetics, and aerodynamic characteristics. 2. Precautions: If your vehicle falls into water, stay calm, call for rescue immediately, and prepare for escape.
When a car falls into water, if you hastily open the window, the speed at which water rushes in will double, causing the car to sink rapidly, leaving no time for escape. I have studied car escape techniques for several years, and the principle of water pressure is crucial: when the car first enters the water, the external water pressure is high while the internal air pressure is low. Opening the window is like opening a floodgate—the cabin fills with water in seconds. At that point, the door won’t open at all because you can’t push against the immense external water pressure, and your body is trapped, struggling to breathe. The correct approach is to unbuckle your seatbelt (don’t forget to release it!), stay calm, and wait for the water to slowly seep in until it reaches about halfway up the door. Once the internal and external pressures are roughly balanced, you can then open the window or door to climb out. Carrying a car window-breaking hammer is also useful for smashing the window in emergencies. Drivers should learn some survival skills during routine car maintenance—this can save lives, especially for those who frequently drive on highways or cross bridges.
