How is the impact or the collision lessened during the "second impact" in a wreck?

The impact or collision during a vehicle wreck can be significantly lessened through a combination of safety features. Each aspect plays a crucial role in enhancing passenger safety.

Wearing a seatbelt is fundamental as it restrains occupants during sudden stops or impacts, preventing them from being thrown around inside the vehicle. This reduces the risk of injury from hitting the interior of the car or being ejected from it.

Utilizing airbags further enhances safety by providing a cushion that deploys in the event of a crash. Airbags are designed to absorb some of the forces involved in a collision, which can greatly reduce the severity of injuries to passengers.

Interior vehicle padding also contributes to safety. The materials used in vehicle interiors are often designed to minimize injury during an impact. This padding can help soften the blow if a passenger strikes parts of the interior during a collision.

Collectively, these safety features work together to mitigate the effects of a second impact that can occur when the vehicle comes to a sudden halt. Therefore, considering all these elements together provides the highest level of protection, which is why the correct answer encompasses all of them.
