Patent ID: 7775739

Claim:
A method for removing track out from a vehicle, comprising: aligning at least one portable track for a vehicle moving onto a road, the track having a plurality of substantially rigid crossbars fixedly attached on top of a plurality of spaced apart supports substantially transverse to the crossbars such that there is an open area between each of the crossbars when said crossbars lie upon said plurality of spaced apart supports; receiving the vehicle onto the at least one track at a first end of the track and allowing the vehicle off the track at the second end of the track, wherein the track corresponds to a substantially linear portion of a path traveled by the vehicle; vibrating the vehicle by moving the vehicle over the crossbars; and shaking the vehicle in at least one of a hopping up and down, a teetering back and forth, and a teetering side to side manner by moving the vehicle over the crossbars; whereby the vehicle picks up debris before the step of receiving, and the vehicle travels substantially linearly over the at least one track in order to vibrate the vehicle and shake off the debris and thereby allowing said debris to fall between said crossbars and said plurality of spaced apart supports before moving onto the road.
