About Us

Guardian Interlock is an independent, family-owned provider of alcohol ignition interlock systems, designed to prevent the operation of vehicles by impaired drivers. We manage offender interlock programs on behalf of state transport authorities, who may require drink driving offenders to have interlocks fitted as part of their rehabilitation. This prevents further drink driving, protects the public and allows the relevant authorities to monitor attempted breaches and intervene where necessary.
