There are a number of defences available. A person who is required to provide a sample of breath into a breath analysis machine should be provided with a print out from the police detailing the results within one hour of providing the sample.
A person required to provide a sample of breath into a breath analysis machine also has the right to ask the operator of the machine to make the necessary arrangements for a blood test.
Finally, if you have any medical reason why you can’t blow into the breath analysis machine, then you must explain your situation to the police who can arrange for you to be transported to the hospital for a blood sample.
There are defences for people with levels exceeding .08. People whose licence is crucial for their employment should speak with a specialised criminal lawyer to ensure that there are defences available.
