Can the car door be opened in water?

It is very difficult to open when completely submerged in water. A car does not sink immediately after falling into water, and you can use the one and a half minutes or even two minutes before sinking to escape through the door or window. Here is an introduction to the classification of water-damaged vehicles: 1. Water level one: The water just reaches the vehicle's chassis. The vehicle floor may get damp, but the possibility of significant water ingress is low, and the impact on the vehicle's electrical equipment is minimal. 2. Water level two: The water reaches half of the wheels. Due to the vehicle's incomplete sealing, water will start to enter the interior. For lower cars, the water level inside may affect the seat adjustment motors and electrical components like heating and ventilation. 3. Water level three: The water almost completely submerges the tires. At this point, the water level inside will completely cover the seat cushions and the central armrest area, affecting a large number of electrical components.
I once drove through a puddle and felt that if the car was completely submerged in water, opening the door was incredibly difficult. The water pressure pushes against the door from the outside, much like the pressure you feel in your ears when diving in a swimming pool, making it impossible to open the door unless the water fills the car and balances the pressure inside and out. In an emergency, experts advise not to waste time trying to force the door open. Instead, quickly unbuckle your seatbelt and attempt to escape through the window. If the window won't open, using an escape tool like a window-breaking hammer to strike the corner of the window is more effective. A car sinks rapidly, leaving only a few dozen seconds to react, so keeping a window breaker within reach provides much-needed peace of mind. For safety, if you end up in water, don't panic—following these steps can significantly increase your chances of survival. If all else fails, call for help or wait for rescue, but act quickly—hesitation is dangerous.
With over a decade of experience in auto repair, I understand that the difficulty in opening car doors when submerged is primarily due to water pressure. Water's high density creates significant external pressure on the doors, especially during initial submersion when the pressure differential is greatest. Forcing the door open is ineffective and may cause hand injuries. Practical advice is to wait a few seconds for water to enter the cabin and equalize pressure before attempting to open the door, or to break a window for quicker escape. Car windows are weaker than doors and can be shattered using an elbow or key, though keeping an emergency hammer in the vehicle is ideal. Additionally, regularly inspecting door seals for wear is crucial, as proper maintenance reduces water ingress risks. Time is critical—the entire submersion process may take just 30 seconds to a minute—so staying calm and acting decisively is key. Sharing this knowledge aims to enhance safety awareness.
As someone who frequently deals with emergency situations, I want to emphasize that if a car falls into water, do not immediately try to open the door. The water pressure will make the door seem stuck and very difficult to move, and attempting to open it may waste precious time. The best approach is to immediately unbuckle the seatbelt and try to break the side window to escape, as the water pressure has less effect on windows. The car sinks quickly, so prioritize ensuring breathing and an escape route. It’s important to keep a window-breaking tool in the car at all times—it can be a lifesaver in critical moments. Safety first: train yourself and your family to react quickly in such situations. Remember this tip: the corners of the windows are the easiest to break.
