There are over 55,000 drivers using a loophole to avoid doing the full test.
Under the current system, drivers can renew their permits multiple times, with some going up to 12 years without a full licence.
The Road Safety Authority is planning a major crackdown on the grey area according to the Sunday Business Post.
John Walsh from The Irish School of Motoring says that this is a cause for concern:
"I'm stunned actually that people in this day in age can get away with that the fact that they can renew it continuously is alarming, to say the least.
"When you think about these people are going around untested, untried in all cases they mightn't be safe and in some cases, they might be very unsafe to drive."
He added that "We have seen all these changes come about but we would definitely think that there's nothing to fear in doing a driving test there's no point in putting it off.
