Road casualties were high when the breathalyser was introduced in Ireland in 1969, according to this 'Wednesday Report'.

Presenter Brian Cleeve says that in the last two years, over 850 people had died on the roads, which was more than had lost their lives in the entire War of Independence. Will the introduction of the breathalyser help reduce the numbers killed in road traffic accidents? 

We need no only need new rules. We need to obey them.

This edition of 'Wednesday Report' examines the issue. It was broadcast on 5 November 1969, two days after new drink driving laws came into force. Other new measures included a blood alcohol limit of 125 mg.
