These charts show the appropriate drive away times for one-part glues at various temperatures and relative humidities. Your auto glass installer should tell you how long your vehicle should sit before you can safely drive away.
Tests performed on glues not allowed to cure properly show just how hazardous driving without allowing for proper curing can be.
