What risks are associated with rolling down a car window if it becomes submerged in water?

When a car becomes submerged, the immediate instinct might be to roll down the windows to escape. However, rolling down a window can be problematic for several reasons. First, if a car is fully submerged, the pressure from the water outside can make it extremely difficult to open any windows or doors. However, if you’re in a situation where the car is partially submerged and the electrical system still functions, opening a window can allow water to flood in quickly, potentially making it harder for you and any passengers to keep breathing while preparing to exit. Additionally, if the vehicle is in motion or in a strong current, opening a window might destabilize the car further, increasing the risk of it sinking more quickly or rolling over. The most recommended course of action is to stay calm, immediately unbuckle your seatbelt, and, if possible, roll down the windows before the water reaches them. If the water pressure is already too high or the electrical systems fail, utilizing a window-breaking tool is advised to create an escape route.
