Make a habit of regularly replacing or cleaning the mouthpiece as part of routine maintenance. Once the mouthpiece is installed correctly, you can proceed to the next step.
Step 3. Power On the Device
Once the mouthpiece is installed, the next step is to power on the interlock device. Typically, this is achieved by turning the vehicle’s ignition to the “on” position without starting the engine. This will activate the interlock device, allowing it to run a quick self-check to ensure that all systems function properly. Following this, the device will prompt you to perform a breath test.
Make sure to follow the device’s on-screen instructions, as they may vary based on the model. It’s essential to wait until the device is ready for a breath sample; prematurely blowing into the device can lead to erroneous results or unnecessary lockouts. The power-on process prepares the device for a reliable breath sample, ensuring the accuracy and efficiency of the interlock system as you continue through the subsequent steps.
Step 4. Provide a Breath Sample
With the device powered on and ready for testing, it’s time to provide a breath sample. Wait for the interlock device to prompt you, then take a deep breath and blow steadily into the mouthpiece. Maintaining a consistent and continuous flow is crucial, as interruptions or weak attempts may result in a failed test and require you to retake it. Follow the specific breath instructions given by the device, such as the duration of the blow. The interlock device will analyze the sample within seconds once the sample is accepted. Ensure you adhere to all instructions to avoid false readings or extended wait times. A successful test will indicate whether you can proceed with starting your vehicle.
Step 5. Wait for Results
After providing a breath sample, the next step is to wait for the interlock device to process your breath analysis. This process typically takes a few seconds as the device measures the blood alcohol concentration (BAC) in your sample. During this time, remain calm and patient. Pay attention to the device’s display, as it will notify you if the sample is acceptable or has any issues. I
f the BAC measured is below the preset threshold, the device will signal that it’s safe to start the engine. However, if the BAC is above the limit, the device will prevent the vehicle from starting, and you will receive instructions on the next steps, which may include waiting a specified period before attempting another test. Always respect the results provided and avoid repeated attempts that may lead to lockouts or penalties.
Step 6. Start Your Vehicle
Once your breath sample has been successfully accepted and your BAC is confirmed to be below the predetermined limit, you can start your vehicle. Turn the key or press the start button to ignite the engine as you would normally. It’s crucial to remember that the interlock device is still active and will continue to monitor your BAC with periodic rolling retests during your drive. Be attentive to any alerts or prompts from the device that may require you to provide additional breath samples, ensuring compliance with safety and legal requirements. Starting your vehicle with a clean test ensures safe travel and adherence to the enforcement program.
Step 7. Perform Rolling Retests
While driving, the interlock device may ask you to perform rolling retests to ensure your BAC levels remain below the legal limit. When prompted, find a safe location to stop or pull off the road, if necessary, to provide another breath sample. Follow the instructions on the device, maintaining a steady and consistent breath flow into the mouthpiece. Rolling retests are designed to prevent circumvention of the system, ensuring ongoing compliance as you operate the vehicle.
