An apparatus and method for automatically tracking each individual vehicle, of a plurality of vehicles, in a race around a track. The device employs RFID tags on each of the vehicles being tracked and at gates adapted to cause the RFID to energize and broadcast the vehicle's identity when a pass through the gate is determined. Collisions of data transmission and resulting loss of identification data are reduced through commands to RFIDs responding and remedied with an inventory command based on most likely respondents. The device can be employed to both track the individual vehicle participants in a race and also to register the participants in the race. Races can be tracked on different courses in different geographic locations by placing the RFID tags on all participants and tracking their progress on the individual remote tracks from a central location.
