A "three-wheeled" vehicle is a type of transportation that has three wheels instead of the traditional four. This design can be found in various forms, including motorcycles, scooters, and some types of cars. Three-wheeled vehicles are often lighter and more maneuverable than their four-wheeled counterparts, making them popular for urban commuting and recreational use. Three-wheeled vehicles can be categorized into two main types: trikes, which are modified motorcycles with an additional wheel for stability, and auto rickshaws, which are small, motorized vehicles commonly used for public transport in many countries. These vehicles can offer unique advantages, such as better fuel efficiency and easier parking.
