RURAL Service Licence (RSL) permit holders who operate beyond their jurisdiction continue to be a challenge for Nadi's municipal authority.
Nadi Town Council's special administrator Robin Ali said many rural-based operators could still be found conducting business within the town's central business district.
"RSL operators have permits to bring rural passengers into town but they don't have a licence to take passengers from town," Mr Ali highlighted at a stakeholder's meeting this week.
"They pick up people from this area and it ends up affecting taxi, bus and other operators that have the appropriate licence to take those passengers."
He put forward a proposal for the Land Transport Authority to colour code number plates so such permit holders could easily be tracked.
LTA public transport unit staff member Frances Vavaitamana confirmed that such a proposal had been made to their management.
"We understand that they can only take their own passengers and operate from a certain point," Ms Vavaitamana said.
She said there was a current freeze on all applications for public service vehicle and RSL operators.
