Auto rickshaws, also known as tuk-tuks, are three-wheeled vehicles commonly used for public transportation in many countries, especially in India and Southeast Asia. They are designed to carry passengers and small goods, offering a convenient and affordable way to navigate through crowded urban areas. These vehicles are powered by either gasoline or compressed natural gas and are known for their compact size, making them ideal for maneuvering through narrow streets. Auto rickshaws typically have a driver in the front and a covered passenger compartment at the back, providing some protection from the elements.
