What safety equipment is required in every vehicle?

The correct answer highlights that every vehicle is required to have seat belts, airbags, and functioning lights to ensure safety on the road. Seat belts are essential as they help restrain occupants during a collision, reducing the risk of injury. Airbags provide additional protection by cushioning the impact in case of a crash. Functioning lights, including headlights and taillights, are crucial for visibility, especially during nighttime driving or adverse weather conditions, ensuring that a vehicle can be seen by others and is safely navigated.

This comprehensive safety equipment plays a vital role in minimizing injuries and deaths resulting from vehicle accidents, aligning with safety regulations mandated for all vehicles. Other options, while mentioning necessary components, do not encapsulate the complete range of safety equipment required by law, which includes the combination of seat belts, airbags, and lights.
