Key: County = the county where the data was collected, not necessarily the county where the vehicle was registered.
Registered = vehicle had a current California registration.
Unregistered = vehicle had an expired California registration.
Front = vehicle's LPN was captured from the front of the vehicle. Because California vehicles only have registration tags for rear license plates, no registration information is available from the front plate.
Dealer = vehicle's LPN was a paper plate or a dealership plate of a newly purchased vehicle being used until the issued license plate is received.
Unknown = vehicles for which either the photographic quality prevented identification of the month if the vehicle had a registration year of 2000 or the year sticker was missing.
