MOT
Windscreens have been part of the annual MOT test since the early 1980s. And, a damaged windscreen - one with a crack or chip, for example, can cause your vehicle to fail the MOT.
However, a lot depends on where the chip is in relation to the driver's field of vision and the size and extent of the windscreen damage. Even a chip on the windscreen as small as a 5 pence piece could be enough to cause your car to fail the MOT test.
