In car accidents, concussions can occur in due to a variety of factors. One of the most common ways that concussions happen in car accidents is when the head strikes an object, such as the steering wheel, dashboard, or window. This can cause the brain to rapidly accelerate and decelerate inside the skull, leading to a concussion.
In addition to direct blows to the head, concussions can also occur in car accidents due to the forces of the impact. For example, if a car is struck from the side, the forces of the collision can cause the brain to rotate inside the skull, leading to a concussion.
