Mud flaps are protective accessories attached to the wheel wells of vehicles, such as trucks and cars. Their primary purpose is to prevent mud, dirt, and debris from being thrown up by the tires, which can damage the vehicle's body and paint. They also help keep the road cleaner by minimizing the amount of material that gets kicked up into the air. Typically made from rubber or plastic, mud flaps come in various sizes and designs to fit different types of vehicles. They are especially useful for off-road vehicles and commercial trucks, where exposure to rough terrain and heavy loads is common.
