If the petition does not contain all the information required by this part, NHTSA notifies the petitioner, pointing out the areas of insufficiency, and stating that the petition will not receive further consideration until the required information is provided. If the additional information is not provided within the time specified by NHTSA in its notification, NHTSA may dismiss the petition as incomplete, and so notify the petitioner. When the petition is complete, its processing continues.
