New laws agreed by Cabinet could see motorists who allow their vehicles to be used by unaccompanied learner drivers face fines of up to €2,000 or six months in prison.
The Road Traffic Amendment follows an examination of the law in this area by the Attorney General Seamus Woulfe.
The amendment will form part of the new Road Traffic Bill, which is set to move to committee stage in the Oireachtas in the coming weeks.
Gardaí will also have the power to seize vehicles driven by unaccompanied drivers.
It will also be an offence for a car owner to allow a person who is not the holder of a driving licence or learner permit to drive the vehicle.
