Or at least they used to be. When the law was drafted in NSW a Random Breath Test was just that. If you passed the test anything more, like a rego or licence check, was an invasion of your privacy as the police hadn't any cause to stop you in the first place. I've tested this on Sydney coppers. Two years ago I was directed to pull over and told I was being subjected to an RBT. After the test was completed and passed the officer asked to see my drivers licence. I refused to produce it, using the same explanation as in the previous paragraph. The copper sent me on my merry way. In the last year a number of my friends and family have been subjected to RBTs (all have passed the test) and have been asked to produce thier licences. Those who have refused have been told they have to. To avoid fights with the coppers they have complied and shown thier licences. If I am pulled for speeding or driving erratically or because my vehicle gives the impression of being unroadworthy then its another story and they can check whatever they like. But an RBT is being pulled for doing nothing wrong. Has the law been changed or are the police taking the piss and misrepresenting the law to suit themselves? Does anyone else have any experience with this situation? What does the law say in other states?
