NSW Environment Minister Rob Stokes said reports from the public of littering from cars, trailers and trucks can now result in a fine.
"Thousands of community members already report littering from vehicles to the EPA each year, so we know there is tremendous support in the community for reporting and a low tolerance for littering," Mr Stokes said.
"We want people to know that, if they litter from a vehicle, they run the risk of being seen, being reported and facing a hefty penalty.
"This research also shows people are less likely to litter if someone's watching. Litterbugs will think twice if anyone in the street can report them for a fine."
Mr Stokes said the new reporting system will be up and running from February 1, and fines will be issued for offences from March 1
Fines for littering from a vehicle range from $250 for an individual, $500 for a corporation, to $900 for aggravated littering.
