Refusing to submit to breath test

A person is guilty of an offence if they fail to comply when asked to provide a breath or saliva sample.

Alcohol ignition locks

A person who is found guilty of a drink driving offence and is a repeat drink driver may be made subject to an alcohol ignition lock (AIL) order. When this order is made, the person must comply with an alcohol interlock condition for a specified period after their licence disqualification period ends.

While an alcohol interlock order is in force, the person is only allowed to drive a vehicle that has been fitted with an alcohol ignition lock. This device prevents the vehicle from starting if alcohol is detected on the driver’s breath. The device must be installed at the driver’s expense.

An alcohol ignition lock order may be for a period of six months to three years.

If the person chooses not to apply for an AIL licence when their disqualification period ends, they remain disqualified from driving until the end of the AIL period that the court has fixed.
