Korea has some 20 million drivers and around 260 000 breath tests are conducted every year, which means that only one out of 80 drivers are tested each year, while in New Zealand each driver is tested, on average, at least once a year. Some people are calling for a lower limit. Is there justification for such a move? The expert response was that there were two general movements: to go to a legal level of 0.2 (zero for practical puiposes) or to 0.5 but with lower limits for novice and professional drivers. Consideration could therefore be given to a lower blood alcohol content for these latter categories. One issue is the large proportion of owner -driver-owners who are not subject to company regulations.
