Windscreen repair and replacement

A small chip away from the edge of the windscreen can often be repaired with resin, if you don't put it off. A long crack or damage right in the driver's line of sight usually means a new windscreen. At the ITP inspection, RNTR 1 accepts, within the area swept by the wipers, a single damaged spot that fits in a circle of at most 10 mm across. On many newer cars, the camera behind the rear-view mirror has to be calibrated after a replacement: ask whether the firm does the calibration and whether it is included in the price.
