Abstract: A protective cover for a vehicle is provided which extends over a portion of the vehicle body to protect the user from soil accumulated on the exterior of the vehicle. The cover includes a sheet of thin, flexible material which is preferably designed for attaching to the interior of a vehicle by a securement member such as hook and loop material, snaps or the like. The a rib or other rigidifying member extends across the width of the sheet to aid in maintaining its extended condition, and may be sewn into a pocket as an aid to grasping. An attachment member releasably connects the sheet to a door of the vehicle so that when the door swings open, the sheet is tensioned and the attachment member releases to deploy the cover over the exterior of the vehicle. A weight is provided along the bottom margin of the sheet to assist in positioning the sheet in covering relationship over the vehicle exterior.
