§ Mr. Peter BottomleyTo ask the Secretary of State for Transport what research evidence he has received on the comparative reductions in numbers of drink drivers in Great Britain and New South Wales since either the year before or the year after the introduction of random tests in New South Wales.
§ Mr. ChopeRandom breath testing was introduced in New South Wales in December 1982. One measure of the subsequent reduction in the numbers of drink drivers is the fall in the proportion of drivers killed whose blood alcohol level was known who were over the limit. This has fallen 179W from 36 per cent. in 1983 to 33 per cent. in 1989. The comparative figures for Great Britain show a fall from 28 to 19 per cent., a fall of nine percentage points.
