Drink driving is one of the main causes of road deaths in South Australia. As part of a wider initiative to tackle this problem, the Mandatory Alcohol Interlock Scheme (MAIS) is aimed at high-risk, serious and repeat offenders. After a period of disqualification from driving, convicted offenders will be required to have an interlock installed in their vehicle for a period of up to three years.
