Section 13 of the Road Transport (Safety and Traffic Management) Act 1999
empowers police to carry out random breath tests.
Such request by the officer arises only if he "has reasonable cause to believe"
that the person was the driver etc. In cases of random stops on the roadway, it
is axiomatic that such belief is reasonable.
Offence:
It is an offence under subsection (2) for the driver to "refuse" or "fail to
undergo" such breath test.
Defence:
It is a defence to a request to undergo a breath test if the person can
satisfy the court that he was unable on medical grounds to undergo such breath
test in accordance with the officer's directions. (S.13(3) )
Further to Defences relating to breath testing, under Section 17 of the Act,
Police are not permitted to carry out a breath test (or breath analysis) in the
following circumstances:
- A person who has been admitted to hospital - unless no objection by the
medical practitioner;
- If the person has been injured and it might be dangerous to carry out a breath
test/analysis;
- After the expiration of 2 hours from the occurrence of the event; and
- At that person's home.
