Excellent reply! You have nailed it! A picture tells a thousand words!
I tried searching DOT numbers at the top of the page, no results!
My suggestion is, when the installer arrives to change the windshield, write down the DOT Number and check the database. Then Google the manufacturer to see if there are any issues.
When doing my research, I phoned the main local windshield warehouse who supplied me with all the DOT Numbers so I was able do the research and find some vision issues with all the windshields! (see my topic above for outcome)
