To break a side window in a vehicle, where should the window be struck?

Striking a side window in a vehicle at a lower corner is the most effective method for breaking the glass. The reason for this is that the lower corners of windows are typically weaker points structurally. When force is applied to these areas, it helps initiate a crack that will propagate through the glass more easily.

The lower corner is also advantageous because it allows the rescuer to stay further away from potential shards that may fly into the vehicle interior. This enhances safety for the person breaking the window and anyone else in proximity.

In contrast, other locations such as the center or the top of the window are not as effective. The center is often reinforced or designed to withstand more force, making it more difficult to break. The top of the window is less effective as well, as it may not provide the same leverage or result in the shattering that occurs more readily at the lower corners. Accessibility does play a role; however, if the lower corner can be accessed, it's still the preferred point for breaking the window.
