THE LTA has reiterated the need for all vehicles to have proper registration plates.
This follows the increased number of new and second-hand vehicles spotted without registration number plates on Northern roads.
Authority CEO Naisa Tuinaceva said: "Everyone must know that operating without proper registration plates is illegal.
"You can't make up your own number plates if you don't have one. I know there are cases where the delay is on us in making plates, but there are also cases where motorists just simply neglect to have it done.
"Also, some motorists lose or damage their number plates and decide to make up their own. This is wrong and unlawful, and there is a penalty for it.
"We don't have plate-making machines in the North but motorists can make arrangements for their orders where plates will be made in Suva and sent to them."
Mr Tuinaceva said those who don't have proper registration plates should liaise with the authority.
"In this case, the LTA will make a temporary plate number for motorists to give them time to work on arranging for a proper one.
"We are once again appealing to motorists to have proper plates to prevent misunderstandings and mishaps."
