Abstract A toughened vehicle windscreen, with a long service life, was found to have an extensive series of scratch marks over the whole area swept out by the windscreen wiper blades. Very little scratching was seen over the remainder of the screen. A collection of 25 other vehicle windows was examined and scratching was shown to be a general phenomenon, the oldest screens being the most scratched. The scratch marks, when present on a windscreen, could be observed on casework sized fragments either by using the specular reflection of white light or by interference microscopy.
