Which of the following is NOT a top cause of fatal crashes?

Using seatbelts is not a top cause of fatal crashes because, in fact, seatbelt use is a critical factor in enhancing vehicle safety and reducing the severity of injuries during collisions. When occupants wear their seatbelts, they are significantly less likely to be ejected from the vehicle and more likely to remain securely in their seats, which can considerably lower the risk of fatal outcomes in the event of a crash.

In contrast, the other factors listed—driving under the influence, failing to yield the right-of-way, and inattention while driving—are recognized as major contributors to traffic fatalities. Driving under the influence impairs a driver’s ability to operate a vehicle safely, while failing to yield the right-of-way often leads to collisions at intersections. Inattention, whether caused by distractions such as mobile devices or other factors, can result in drivers missing critical situations that require timely responses, further increasing the likelihood of accidents.
