Arizona pinstriping (or Arizona pinstripes, also known as Carolina Pinstriping) is the colloquial term for the thin, shallow scratches along the sides of trucks and SUVs usually formed when branches, twigs, or thorns scrape along the side of the passing vehicle. This term likely originates from Arizona, a U.S. state well known for its adventurous Wild West culture and numerous off-road trails. Generally, scratches that are severe enough to remove layers of paint are not considered Arizona pinstriping.
