29-A M.R.S. §1915: Windows

1. Safety glass. A motor vehicle must be equipped with safety glass wherever glass is used in partitions, doors, windows or windshields.

"Safety glass" means a product composed of glass or of other materials, manufactured, fabricated or treated to prevent shattering and flying of broken glass.

The Commissioner of Public Safety may maintain a list of the approved types of glass.

Replacements of glass partitions, doors, windows or windshields must be made with safety glass.

2. Window repairs. When a window, other than the windshield, is broken, the operator may repair the window by temporarily replacing it with an opaque substance until there is a reasonable opportunity for replacement.
