A splash guard is a device used to protect a vehicle from mud, dirt, and other debris. It is composed of three parts: a FENDER, an APRON, and a mudflap. A FENDER is a curved piece of metal or plastic that is attached to the side of a vehicle and helps to protect it from mud and debris. An APRON is a flat piece of material that is attached to the bottom of a vehicle and helps to keep mud and debris from entering the engine compartment. A mudflap is a flexible piece of material that is attached to the rear of a vehicle and helps to prevent mud and debris from being thrown up by the tires. Together, these three components form a splash guard, which helps to protect a vehicle from mud and debris.
