STANDARD/COMMON BREAKS
BULLS-EYE
breaks are almost always on the outside layer of a windshield, and they are
very common. A true bulls-eye does not have any radial cracks. There is a
small hole or pit at the point of impact on bulls-eyes. The broken piece of
glass is conical in shape, with its tip at the surface of the windshield and
its base at the plastic interlayer. Looking at this break from the outside
of the vehicle, the size of most bulls-eyes are usually 3/8" to 1" in
diameter.
PARTIAL BULLS-EYE
breaks are caused by a very small pebble striking the windshield at high
velocity. Typically, these breaks are no larger than about 1/2" and have a
very small pit at the impact point.
STAR
breaks consist of an impact point with one or more radial cracks extending
from the break. Star breaks vary in size and number of radial cracks. Some
are only 1/4" long with only one crack. A true star break never has a large
cone beneath the impact point.
COMBINATION
breaks usually consist of a Bulls-eye with one or more radial cracks
extending from the impact point.
ADVANCED/UNUSUAL BREAKS
OVERLAPPING
breaks with several impact points:
LARGE PIT
opening in center of Bulls-eye or Combination break:
LARGE COMBINATION
break with large radial crack extending from the break:
WIDE CRACK
with open crack on one edge. (Commonly called a baseball break)
IMPACTED BULLS-EYE
break. Small cracks exist in the cone of the break that do not connect with the rest of the break:
CIRCULAR BREAK
with no cone. This break resembles a bottle cap. The inside edge of the circle is usually cracked to
the surface:
ANGEL WINGS This is a crack, usually less than an inch, that has tight ends that twist to the center, or impact point.
CRESCENTS, these are "moon-shaped" fractures, sometimes with small radial cracks, that are often deep enough to penetrate the inner plastic layer.
