Store, carry and transport glass as near to vertical as possible.
If you are transporting a number of sheets, place paper between the sheets to avoid scratches and vibration damage or breakage. The glass should be tied tightly together, preferably on a rack.
If you do not have a rack you can put into the back of your vehicle, and put the seat belts around the glass to keep it from flying forward in the event of an emergency stop. Cushion the seat belts from the edges of the glass to avoid cutting the belt with emergency breaking.
