The
windscreen must be free from cracks and fractures within the
drivers field of vision as displayed on the right hand diagram.
It acceptable to have small stone chips but having these repaired
when they are small will avoid later
failures
when the chips spread. Small chips and cracks can be enlarged when
the screen is stressed if the car goes over bumps etc.
Mirrors
Rear view mirrors must be secure and intact. All rear view mirrors
must be adjustable. There must be at least ONE rear view mirror.
Mirrors must show a clear view of the rear view. The MOT tester will
use your rear view mirrors to check the operation of the rear lights
during the test.
