What Is VicRoads Interlock Installation?
VicRoads Interlock Installation refers to the mandatory fitting of an alcohol interlock device in a vehicle after certain drink driving offences in Victoria.

If alcohol above the permitted limit is detected, the vehicle will not start. VicRoads Interlock Installation is designed to prevent drink driving and improve road safety while allowing drivers to regain conditional driving privileges.
