Side-impact accidents, also known as T-bone collisions, occur when one vehicle strikes the side of another, forming a "T" shape. These accidents often happen at intersections when a vehicle runs a red light or fails to yield. The impact can be severe, especially for the occupants of the struck vehicle, as the side doors provide less protection than front or rear structures. In side-impact accidents, the risk of injury is heightened due to the proximity of the occupants to the point of impact. Safety features like side airbags and reinforced door beams can help reduce injuries. However, the effectiveness of these features depends on the speed and angle of the collision.
