taken from the independent:
QUOTE ONE in every five drivers has been breathalysed in the past year, according to new figures from an AA Ireland survey.
Following a poll of 5,300 motorists, the AA also found that six per cent of drivers had provided a breath sample twice in the past 12 months and that Dublin drivers are more likely to be tested than those living elsewhere in the country.
a poll of 5300 motorists? so are they not dividing those results into the population and getting what they assume as an accurate estimate?
