Hence, it is necessary to strive for the effectiveness, completeness of scene inspect and the systematicness of the investigation technology. The pieces of paint and scrape of vehicles in accidents are the important things of investigation technology, and hard to discriminate from other investigation technology. It is a topic worth to study to build scratch direction and characteristics on investigation with generalization and systematicness. We have analysed and studied the scratch direction and characteristics of vehicle painting, and present the outcome. We also found that there existed repeat scratches with vehicle-vehicle particularly. It is not only harder to determine the direction but less reference about this. Scratches with motorcycle-vehicle are unapparent and generally rubbed off. Repeat scratch is more rare. Because of thinking about the degree of difficulty and the danger to get data, this study focus on vehicle-vehicle without considering motorcycle-vehicle. This study will be based on the results of the study of single scratch characteristics and direction of car painting with the topic of scratch direction and characteristics to discuss and research the phenomena of repeat scratches by microviewpoint. The study will draw up the procedure of how to use scratch characteristic in investigation after an accident was happened. The result could be the important reference of investigation.
