A passenger vehicle is a type of transportation that carries passengers from one place to another. Common examples of passenger vehicles include cars, trams, buses, sedans, jitneys, autos, and motorbuses. Cars are typically four-wheeled vehicles with an internal combustion engine, while trams are rail-based vehicles that run on tracks. Buses are large vehicles that can carry many passengers at once, and sedans are four-door cars with a trunk. Jitneys are small buses that usually operate on a fixed route, autos are cars with a self-propelled engine, and motorbuses are large buses powered by an electric motor. All of these vehicles are used to transport people from one place to another.
