A deal announced between the Irish and UK governments will mean driving disqualifications in both countries will be recognised from February next year.
It means should a British driver get disqualified in Ireland, the ban will still apply in the UK, and vice-versa.
The agreement between the two governments is the first under the terms of the 1998 European Driving Convention. Ministers said the deal represents the first practical step in Europe.
Transport minister Paul Clark said: "Britain has one of the best road safety records in the world but we need to do everything we can to improve even further.
"If a UK driver commits a serious offence while in Ireland their ban should still apply when they return home.
"These measures will keep dangerous drivers off our roads by ensuring that disqualified drivers are not able to escape their punishment."
Offences covered by the 1998 Convention include reckless or dangerous driving, hit-and-run driving, driving under the influence of alcohol or drugs, speeding, and driving while disqualified.
The agreement does not apply to disqualifications under the totting up or penalty points procedure.
