A vehicle is a machine designed for transporting people or goods from one place to another. Common types of vehicles include cars, trucks, buses, motorcycles, and bicycles. Vehicles can be powered by various sources, such as gasoline, diesel, electricity, or human effort. They play a crucial role in daily life, enabling travel and commerce. Vehicles are typically equipped with wheels, which allow them to move smoothly on roads. Some vehicles, like boats and airplanes, are designed for travel over water and through the air, respectively. Safety features, such as seat belts and airbags, are important for protecting passengers during travel.
