Each state and territory of Australia has its own regulations and acts for the operation of tow trucks. Tow trucks are generally divided into two categories, either by standard, trade and private towing or Accident Towing. Accident Towing tow trucks are clearly identifiable by number plates ending in either "ATT" or "TT". Tow trucks that are not endorsed for accident towing may use general number plates of any combination pursuant to each states own registering system. An example of a statute regulating the operation of tow trucks and the towing industry in Victoria is the Victorian Accident Towing Services Act.
