Please stop adding nonexistent categories to articles. I noticed that you added a nonexistent category "Pickup trucks" to several articles, even though there is already a category of the same purpose "Pick up trucks". Please stop adding categories to articles if the categories don't exist. Please check to make sure a category exists before you add it to a page. If you do not stop, you will receive another warning, and should it continue beyond that you will be blocked. Please review our rules. Thank you.
