Five people have been killed in four separate road accidents in Co Donegal since yesterday.

The victims range in age from 18 to 59.

Superintendent Vincent O'Brien of Letterkenny Garda Station said it seemed the road safety message is still not getting through in the county.

Up until yesterday road deaths had been down on the same period last year - three people had died compared to eight last year. 

Now with five people killed this weekend alone, the number of road deaths in Donegal is the same as last year, eight.

The Donegal Road Safety Working Group issued a strong reminder to drivers in advance of the bank holiday weekend to drive with care. 

The group has been running an awareness campaign launched by Gay Byrne which has the stated aim of saving lives and reducing serious injury on Donegal roads.

That campaign was carried through to yesterday's St Patrick's Day parade in Letterkenny, where the theme was road safety but Supt O'Brien says the message still does not seem to be getting through.
