Although head-on collisions are rare, they often result in severe or catastrophic injuries when they occur. Head-on collisions make up roughly 10% of all traffic fatalities. When two cars traveling towards each other collide, the impact that occurs is twice as severe. In addition, most passengers sit in the front of the vehicle where the impact occurs. As a result, these passengers are more vulnerable to life-threatening injuries such as brain trauma, damage to vital organs, and spinal cord injuries.
