A car trailer is a type of vehicle designed to transport cars or other vehicles. It is typically towed by a truck or SUV and comes in various sizes and styles, including open and enclosed models. Open trailers are often used for transporting multiple vehicles, while enclosed trailers provide protection from weather and road debris. Car trailers are equipped with features like ramps for easy loading and unloading, tie-down straps to secure the vehicle, and sturdy frames to support the weight. They are commonly used by car dealerships, auto transport companies, and individuals needing to move vehicles for various reasons.
