Windscreen

From the driver’s seat, check the view of the road through the swept area of the windscreen. Only fail the

vehicle if there is damage or an obstruction -

 in zone A, greater than a 10mm diameter circle and which materially affects the driver’s view

of the road.

 in the remainder of the swept area, greater than a 40mm diameter circle and which materially

affects the driver’s view of the road.

Note: Where any damage or obstruction does not impair the driver’s view of the road, the vehicle should

pass. If it only affects the driver’s view of the sky or the bonnet then this is not to be considered a reason for rejection.

Dynamo ' has absolutely no material effect on the view of the road?' The view between the wiper and damage is of the wall which represents the road?

The criteria of Drivers View of the Road is in the drivers direct eye line. Looking at that crack may cause a crash but it's not a Fail for sure

had one where I refused to remove his tw@t nav cos it looked like hed glued it to the screen,he sat there tugging away at it,off it came with a loud crack as the screen split down the middle.....laugh?i nearly bought a round!

paul sorry I'm not 100% sure what you are saying above. Are you saying that the damage along the lower side of the windscreen is actually going to affect the drivers view of the road?

ht not sure I see any problems there, I can certainly see inside the building through the screen clear enough to say that my view of the road would not be materially affected by those items in the screen/mirror area. 

Yes, between the wiper and damage is the wall which represents the road Dynamo.

Morning Paul
As this is a standards issue I have forwarded it to their team for a response.
As I understood it though the extra line was added due to many failures for damage greater than 10mm for example but when in the drivers seat the effect was minimal and the driver had a perfectly good view. So it was difficult to justify a fail.
If you had damage less than 10mm then that size was deemed so small that it would not affect view enough anyway.
But I will await standards response and send on to you.

Materially = in a significant way; considerably.

Basically, anything in the drivers view of the road has to affect the view a lot Paul.

The criteria is usually in the wording. Materially is used as a submodifier to the existing Fail Criteria.

Edited to add an example:

This would Fail....

I would pass and advise. My reasoning is that although the crack passes through the view of the road in front of me, it will not materially affect that view. Unfortunately, although the question has now been asked of DVSA, I feel we will probably be no wiser after the answer is given, going by previous history. We will still be making our own mind up. Ah well, just as well we all know what we're doing.

Dynamos crack fails because it is described as running from end to end of the windscreen and it can be seen to pass through the sweep of the wiper blade.
