If a person is convicted of certain drink driving offences in the Northern Territory, and they have previously been convicted of at least one in the past, they may be required to participate in the Alcohol Ignition Lock (AIL) program in addition to a mandatory period of disqualification from driving. Depending on the severity of the offence, the court may order an AIL participation period ranging from six months to three years.

At the end of the mandatory disqualification period, a person can apply to have an AIL device installed and will hold an AIL licence for the length of time prescribed by the court. If the person opts not to take part in the AIL program, they may serve out the length of time as an additional disqualification period.

To apply for an AIL licence, a person must have held a driving licence (other than a learner licence) within the previous five years and completed the Drink Driver Education course relevant to the offence.
