THERE is one illegally parked truck per kilometre on Fairfield's roads, according to Mayor Frank Carbone.
"In the past two months council rangers have been working day and night monitoring almost 600km of roads in our LGA," Mr Carbone said.
"They have issued almost 600 infringement notices to those parked illegally."
The council has targeted large trucks - five tonnes and over - and particularly when they are parked for more than an hour. Mr Carbone said it was part of an effort to prevent noise and increase safety for local neighbourhoods.
"Many residents need trucks to earn their living and we understand that this is an important part of their livelihoods," Mr Carbone said.
"We want to encourage truck owners to continue with their livelihoods, but in a manner that limits the impacts on our community."
Mr Carbone said local streets were not to be used as transport depots by large companies.
"There are many locations across our city where truck owners can leave their trucks without affecting residents, including industrial zones," Mr Carbone said.
"Council also has a truck stop facility at Victoria Street in Wetherill Park that offers many amenities required by truck drivers."
Mr Carbone encouraged truck drivers to use the authorised heavy vehicle parking area between 6pm and 6am from Monday to Friday, and all day Saturday, Sunday and public holidays.
