Tim, You may need to use a series of fountains or smoke plumes with a fast rise and a slow fall and decay. You would need to set up the plume series so that each plume starts when the vehicle passes overhead. A plume would rise quickly and then slowly fade and the particles sink. If you wanted to have a track in the sand remain after the vehicle passes you whould probably want to use an animated bump map on the ground plane. Does this sound like the effect you are looking for? Terry Gilbert Forcade & Associates
