You will require this approval if you intend to supply alcohol interlocks for motor vehicles. An alcohol interlock is a device capable of testing the alcohol content of a person's breath and preventing the car from starting if it is above a prescribed level. The type of alcohol interlock you intend to supply must also be an approved alcohol interlock device.
Please consult the responsible agency for more information and to ascertain the level of compliance (if any) that may be required.
