The Land Transport Authority says it will continue tracking down the large number of illegal and pirate taxis on the roads.
The Authority has started seizing carriers operating illegally as public service vehicles on Fiji's roads.
The warning comes as the authority conducted a follow-up operation to crackdown on illegal operations throughout Fiji
LTA public relations officer Eroni Volavola said the operation was in its second week.
He said so far the Authority had been able to track down some illegal vehicles being used as public vehicles.
"The operation is basically to track down the number of illegal vehicles that are now operating on our roads," he said.
