Why is it important to break or roll down windows after a crash in water?

Rolling down windows or breaking them after a crash in water is crucial primarily to make it easier to escape from the vehicle. When a car is submerged, the interior can quickly fill with water, making it difficult to open the doors due to the water pressure outside. By rolling down the windows or breaking them, occupants can create an exit route, facilitating a faster escape and potentially saving lives.

This action also helps reduce panic and confusion during an emergency, as having a clear path to escape can significantly lower the stress of the situation. Additionally, creating an opening allows the water in the cabin to equalize with the outside pressure, further easing the ability to open the doors. Understanding this instinctive reaction can be essential in a survival scenario, highlighting the importance of being prepared for unexpected situations on the road.
