### What is a blind intersection?

A blind intersection is a place where roads cross and do
not provide a good field of view of the traffic about to cross your
path. Thus, you enter the intersection "blind" to any approaching
vehicles. This can be a very dangerous situation even at moderate
driving speeds.
In California, a "blind intersection" is an intersection when
you cannot see at least 100 ft in both directions on the
intersecting road.
