The definition of Accident in the law of the United States, as defined by the lexicographer Arthur Leff in his legal dictionary is: 1. A state of affairs or incident brought about by accidental means.
What causes accidents is an unexpected or unplanned disruption in a vehicle's velocity, linear or angular, due to hitting something or simply not anticipating or addressing the change properly. In other words, it's not the motion but the disruption of it.
