  We describe impulsive gravitational pp-waves entirely in the distributional
picture. Applying Colombeau's nonlinear framework of generalized functions we
handle the formally ill-defined products of distributions which enter the
geodesic as well as the geodesic deviation equation. Using a universal
regularization procedure we explicitly derive regularization independent
distributional limits. In the special case of impulsive plane waves we compare
our results with the particle motion derived from the continuous form of the
metric.
