Federal cracked windshield regulations
Federal regulations require drivers to have a clear vision of the road. Windshield cracks or chips smaller than ¾-inch in diameter are permitted if they are not located within 3″ of another crack.
Any cracks or chips or other damage which can potentially obstruct clear view of the road must not be within critical vision area, defined as area directly above the steering wheel, two inches from the top and one inch from sides.
