The Automobile Association of the Northern Territory is calling on the Government to explain how it will spend the money it will get from increasing the cost of car registration.
Vehicle registrations costs will rise by up to 18 per cent following the Government's mini-budget that was unveiled on Tuesday.
AANT general manager Eden Bell says there is nothing in the detail to explain where the cash will go.
"I think motorists deserve clarification from the CLP," he said.
"We need to know where that money is going.
"It very much looks like motorists are an easy target and they are going to be slugged accordingly." Mr Bell also says it is unfair to charge motorists extra if they choose to pay their motor vehicle registration over the counter, rather than on-line.
Under the Government's new measures, motorists will be charged $20 if they pay their car registrations at a motor vehicle registration office.
Mr Bell says people should be rewarded if they pay on-line but not penalised if they don't.
"I think it is the wrong approach to say that you're going to be automatically penalised for going into the MVR," he said.
"I think it should be the quite the opposite."
