I WOULD like to see some hard evidence to support the call for drink-drive limits to be reduced from 50 to 35 micrograms of alcohol per 100ml of blood.

Whenever we read in newspapers or see on TV reports of collisions where alcohol has been a major factor, it is invariably because the person responsible is way over the current limit.

Sometimes two, three or even four times the legal limit. Lowering it from 50 to 35 will make no difference in these situations.

What we need to know is exactly how many collisions have occurred where the alcohol level has been between 35 and 50 micrograms; and therefore where a reduction in the limit might actually make a difference.
