In a motor vehicle crash, what injuries are commonly associated with seatbelt use?

Seatbelts transfer the forces of a crash to the torso, so the characteristic injuries are those that occur along the belt path. The best choice describes a pattern you often see: bruising and contusion across the chest and abdomen where the belt sits (the belt sign), which can signal underlying internal injuries; neck strain from the sudden deceleration; possible superficial lacerations from the belt or buckle; and, in more severe cases, internal injuries to abdominal organs from compression. This combination reflects how restrained occupants move and stop in a crash, with the belt guarding against ejection but also concentrating forces on the chest, abdomen, and neck. Other options are not as comprehensive. Facial fractures alone ignore the belt path injuries common with restraints. Pelvic fractures alone miss the chest/abdomen and neck injury patterns. Saying no injuries are expected runs counter to the mechanism of restraint in high-energy crashes.
