New measures may be introduced to put the brakes on a loophole that allows learner drivers to avoid taking their driving test.
Latest figures show that over 125,000 learner permit holders have never taken a driving test - including some who have been learner drivers since 1984.
Current rules allow a learner to renew their permit once they book a full test, but are not required to provide proof that they actually sat it.
It was reported on Tuesday that up to 500 people per week are booking tests and then failing to show up.
It is understood that the Department of Transport is considering several measures that will stop long-term provisional drivers from skipping their test.

Some of the proposals being explored include increasing the cost of a renewing the learner permit, forcing drivers to secure lessons before renewing, and reducing the period of validity of a renewed provisional licence from one year to six months.
RSA communications manager Brian Farrell insists that efforts are being made to stop permit holders from exploiting the existing loophole.
Mr Farrell said: “Learner drivers who adhere to existing regulations are not breaking the law and are not a safety risk on our roads.
“We are concerned, however, by a number of people who are not sticking to these laws.
“Some people are booking a test, not turning up and reapplying for a learner permit.

“We have put recommendations to the Department of Transport in relation to addressing this issue.
“These individuals are taking a huge risk and the threat of enforcement has never been greater.
“Since the Clancy Amendment was introduced over 700 vehicles have been seized by An Garda Siochana from learner drivers.”
Mr Farrell adds that the risk of prosecution for driving without a fully qualified driver is forcing permit holders to attempt a full test.
He said: “Since the implementation of the Clancy Amendment, we have seen a 30% increase in applications for full tests.
“We only now in a position to tackle waiting lists for tests, having hired a number of additional driving test assessors.
“When you consider that a motorist could save as much as 50% on their insurance premium by passing, it makes sense to apply.
“We realise there are some genuine people who are nervous about taking the test be we are encouraging these people to give it a go.”
