How an alcohol interlock device works
Using an interlock is easy, easier than most people expect. An interlock is a small breathalyser wired to your car's ignition. Before you start the engine, you blow into it and as long as it doesn't detect alcohol, the car starts as normal. Every so often while you're driving the interlock will call for a test to confirm you're still good to go. All interlock data is recorded for NZTA as part of your licence conditions.
- Monthly servicing takes 10-15 minutes
- Our interlocks include theft and fault warranty
- Our interlocks are small and discreet
- All data is stored securely
