MOT Question

Is a cracked windscreen an MOT failure ?

The crack itself runs across the bottom of the windscreen and in no way does it enter into the drivers field of vision, its basically in line with the windscreen wipers.

From testers' manual. http://www.motuk.co.uk/manual_830.htm
Zone "A" is the important bit. Maybe a fail if the cracks in there and it's size. Reasons for rejection relevant for zone "A" are bottom right of the page.

I believe if the crack is more than 10-mm in length and is in the swept volume of the windscreen wipers, it's a failure. There zone A and Zone B. The latter is passenger side field of vision and the former, the driver side.

The crack in no way does it enter the sweeping zone or zone A just a damn site bigger than 10mm, so should pass according to that.

Mr Pedant's corrected that!:p
Zone "B" doesn't seem to exist in the Testers' Manual?

This sounds like it could go either way.
If it runs across the bottom of the screen, if the wipers sweep down onto it, it's in the swept area. A large crack should fail.
Some of mine would be, I have one car the wipers sweep near enough onto the rubber.
Another one would technically pass, as the wipers stop about an inch above the bottom (if the crack was in that area)
Move your wipers up if you need to.
