What safety feature is commonly used in vehicles to prevent ejection during a collision?

Seat belts are designed to restrain occupants during a collision and play a crucial role in preventing ejection from the vehicle. They keep individuals firmly in their seats and minimize movement, which significantly reduces the risk of being thrown from the vehicle in the event of a crash. By securing the passenger to the designated seating area, seat belts help to maintain control over body position, thereby increasing the effectiveness of other safety features, like airbags.

Airbags, while essential for reducing injury by cushioning the body on impact, do not prevent ejection on their own. They are designed to deploy after a seat belt has done its job of keeping the occupant in place. Anti-lock brakes and traction control systems primarily enhance vehicle stability and control during driving rather than serving directly to protect occupants during a collision. Thus, seat belts are the most effective safety feature for preventing ejection during an accident.
