Plans to introduce a cross-border penalty points system between the Republic of Ireland and Northern Ireland have suffered a setback.
The department of the environment in Northern Ireland has confirmed that work on the proposals has been paused due to the complexity of the issues involved.
At the moment, motorists from one side of the border who commit traffic offences in the other jurisdiction cannot have those endorsements enforced in their own area.
Motorists can escape penalty points by simply crossing the border.
The governments in Dublin and Belfast wanted to close that loophole.
New laws allowing mutual imposition of penalty points were due to be introduced next year.
That is now unlikely to happen as the department of the environment in Belfast said the project has been paused due to the complexity of the issues involved.
Minister for Transport Leo Varadkar has also conceded that there are legal matters that need to be addressed.
However, he said he remained fully committed to the cross-border scheme and was confident it would proceed.
