Which of the following describes a potential hazard of improperly wearing a seat belt?

Improperly wearing a seat belt can indeed lead to internal injuries during an accident. When a seat belt is not positioned properly, such as being worn across the abdomen instead of over the pelvis or not being snug against the body, it can cause excessive force on the internal organs in the event of a crash. This can result in serious injuries, such as organ damage or internal bleeding, which are significantly more dangerous than the injuries typically caused by correct seat belt usage.

Other options, while they may touch on aspects of seat belt wear, do not directly characterize a critical danger associated with improper usage. The discomfort of a seat belt does not compare in severity to the potential for serious internal injuries, and while improper use may affect the performance of airbags, the immediate danger lies in the physical impact on the body during a collision. Additionally, improperly wearing a seat belt can impact how effectively it restrains the occupant, but it does not directly affect driving performance, which is a consideration separate from seat belt safety.
