A "passenger" is a person who travels in a vehicle but does not operate it. This term is commonly used in the context of transportation, such as in cars, buses, trains, and airplanes. Passengers rely on drivers or pilots to navigate and control the vehicle while they enjoy the journey. Passengers may have specific rights and responsibilities depending on the mode of transport. For example, in an airplane, passengers must follow safety regulations and instructions from the flight crew. They may also need to purchase tickets, similar to how train or bus passengers do, to secure their place on the vehicle.
