Question 3: If a crack extended into the thickness of the glass at such an angle as to measure 1/4’’ or more, measuring from the top edge of the crack on the outside surface of the windshield to vertical line drawn through the windshield to the far edge of this angled crack on the inside of the windshield, would this constitute a crack of 1/4’’ or more in width as defined in § 393.60(b)(2)?

Guidance: No. The crack, in order to fall outside the exception, would have to be a gap of 1/4’’ or more on the same surface of the windshield.
