New calls to lower the alcohol limits for driving include this supporting claim;
Australia has had a 14 per cent drop in alcohol-related crashes since the 1980s, when it lowered the blood-alcohol limit to 50mg - the upper limit recommended by the World Health Organisation.
That's hardly "compelling evidence".
In New Zealand in 1985 there were 2731 crashes with driver alcohol as a factor. 238 were fatal.
By 2005 that had dropped to 1435 with 100 fatal. A 47 percent drop. Without lowering the limit to 50gm.
And the constant blaming of the lowered drinking age for drink-driving doesn't hold up under scrutiny. In 2005 the percentage of 15 -19 year-old alcohol affected drivers involved in fatal crashes was 20 - down from 33 in 2000, after a sharp rise when the drinking age was lowered. The average over the ten years to 1999 was 30. So that age group is improving its statistics.
