Additional breath tests are required at random time intervals to check the driver has not consumed alcohol since the engine was started. After you successfully complete the initial breath test, and the engine is still running, the interlock will continue to request breath samples during your trip at random intervals as follows:
- The first retest will be requested 3 – 10 minutes after engine starting.
- Subsequent retests will be requested 15-60 minutes after the previous random retest has been passed, for the duration of your travel.
- The device will allow 7 minutes for you to safely pull over and complete your retest. DO NOT TURN OFF THE ENGINE
- TAKE NOTE the device will continue to request random retests while the engine continues to remain running. Even if you have reached your destination, if the device asks for a breath sample you must provide it before turning your ignition off.
- DO NOT leave your vehicle running and unattended as you may miss a breath test which will record an error on your handset.
**WHAT HAPPENS**
If a random retest fails or is missed, the lights and horn will sound. It is recommended you pull over to a safe location and turn off the vehicle engine which will stop the sounds. This may result in a temporary lockout. After the count-down has ended you will need to provide a successful breath test to start the car.
