If you're pulled over for a random breath test, and you've had a few drinks, is it better to refuse to give a breath sample? Is the fine for refusing to give a breath sample better then losing your licence for drink driving?
In NSW, if you refuse the breath test you will be arrested and taken back to a police station. If you refuse again at the station you will be charged with refuse breath analysis (drink driving). The penalties for refuse breath analysis are the same for High range PCA. So it is not a real good idea in NSW. I am sure the other states are likely to be the same.
In Queensland you're breath-tested at the roadside and then on a larger machine. It is an offence to fail to provide a sample on either occasion. Failure to provide a sample on the larger device will see a person dealt with by the Court as if the had a reading of 0.15%.
