Number plate warning labels
All vehicles powered by gaseous fuels, such as liquefied petroleum gas (LPG), liquefied natural gas (LNG) or compressed natural gas (CNG), must be fitted with warning labelling on their number plates.
Manufacturers and owners of hydrogen- and electric-powered vehicles, including hybrids, are also required to display a number plate warning label.
The Motor Trade Association (MTA) of South Australia supplies labels for hydrogen vehicles, hybrids and electric vehicles. The labels can be purchased directly from MTA Print in Royal Park (telephone 8440 2666).
Label requirements are fully detailed in the attached Vehicle Standards Fact Sheet .
