What is the purpose of wearing a seatbelt while driving?

Wearing a seatbelt while driving serves a critical safety function, primarily to reduce the risk of serious injury or death in the event of a crash. One of the key purposes is to prevent occupants from being ejected from the vehicle. During a collision, the forces involved can cause unrestrained passengers to be thrown from the car, which significantly increases the likelihood of fatal injuries. Seatbelts are designed to keep individuals securely in their seats, minimizing movement and thus enhancing their chances of surviving a crash.

In the context of other options, while comfort and posture may benefit from seatbelt use, they are not the primary reasons for their mandatory application. Similarly, avoiding speeding tickets is unrelated to seatbelt usage, as enforcement focuses on speed limits, not seatbelt compliance. Therefore, understanding the essential role that seatbelts play in enhancing safety during vehicle operation is crucial for all drivers and passengers.
