Most Atens and Apollos do, but there are a few exceptions.
Asteroid 2012 DA14's orbit is very Earth-like, and does not
cross into the main asteroid belt. In fact, 2012 DA14's orbit
was changed enough by its close Earth flyby in February 15th, that
its classification was changed from an Apollo to an Aten after the
flyby.
