From today, Irish license holders who are disqualified for driving offences in the UK, will automatically have their ban applied here as well.
The Minister for Transport has signed an order allowing mutual recognition of disqualifications between the UK and Ireland.
Those affected will include drivers disqualified for dangerous driving, hit and runs, and drink-driving.
Minister Shane Ross says the move should help to save lives.
UK drivers disqualified by the Irish Courts will also have their bans enforced in the UK.
