A CROSS-BORDER driving ban will go ahead as promised next year, the Department of Transport said yesterday. Although the tough new measure is not included in the road safety legislation before the Dail, the department denied it had been long-fingered. And it insisted that the ban would come into force next year. It will mean that a ban imposed in the North or Britain or on the Isle of Man will automatically disqualify that motorist from driving on Irish roads. Irish drivers banned here would similarly be banned there. However, the new ban will not plug the gap in the law which allows law-breaking motorists from other jurisdictions to avoid penalty points in Ireland. The mutual disqualification was agreed earlier this year by the British-Irish Council. It will cover bans for offences such as drink driving and speeding.
