In the following cases a police officer must give you a notice immediately suspending your licence for 28 days:
Repeat drink-driving – if you’ve driven with a breath-alcohol level of more than 400 micrograms or a blood-alcohol level of more than 80 milligrams, and you’ve already been convicted of a drink-driving offence in the last four years (400 mcg and 80 mg are the levels over which adult drivers will get a criminal conviction, rather than just an on-the-spot infringement notice)
Serious drink-driving – if you’ve driven with a breath-alcohol level of more than 650 micrograms or a blood-alcohol level of more than 130 milligrams
Refusing a blood test – if you’ve failed or refused to have a blood test when required to
Serious speeding offences – if you drove at more than 40 km/h over the permanent sign-posted speed limit, or more than 50 km/h over a temporary limit (but this doesn’t apply if you were caught by a speed camera).
When you’re given a suspension notice in these cases, you must immediately hand over your licence to the police officer.
