What vital information do safety cards provide to passengers?

Safety cards are essential tools designed to ensure passenger safety during air travel. The vital information they provide includes emergency procedures, such as how to use safety equipment, the locations of emergency exits, and instructions for evacuating the aircraft in case of an emergency. This information is crucial, as it prepares passengers for various scenarios that may occur during a flight, ensuring they know what to do to protect themselves and others.

While other options may involve useful information for passengers, they do not directly pertain to immediate safety procedures in emergency contexts. For instance, flight itineraries and meal options, airline policies and contact numbers, or flight attendants' personal bios, while informative, do not serve the primary purpose of facilitating safety and preparedness during an in-flight emergency. Therefore, the focus of safety cards on emergency procedures is what distinguishes their critical role in airline operations.
