Blow and Go ignition interlock devices have emerged as a powerful tool in the fight against drunk driving.

What is a “Blow and Go” Device?

People commonly use the colloquial term “blow and go” to describe an ignition interlock device (IID). An IID is a breathalyzer device that gets installed in a vehicle, and it mandates the driver to provide a breath sample prior to starting the car. By measuring the driver’s blood alcohol concentration (BAC), the device determines if it exceeds the predetermined limit. If it does, the vehicle will not initiate. The term “blow and go” originates from the act of blowing into the device before being able to start the vehicle. Courts often require this device as a condition for individuals who have been convicted of driving under the influence (DUI) or other alcohol-related offenses.

It’s small enough that it doesn’t get in the way of your everyday routine but is powerful enough to provide quick and accurate results. The on-screen directions are easy to understand. The ALCOLOCK WR3 is incredibly accurate, which means you can be confident in the device and its readings

How to Use the ALCOLOCK WR3

Using the ALCOLOCK WR3 is a straightforward process. Simply follow the on-screen instructions to determine when to blow into the device. Provide a continuous breath for four to five seconds. Subsequently, the device will notify you if you have passed. In the event of a successful test, you will receive directions to start your car. All pertinent information is stored within the device and can be downloaded if necessary. Random testing intervals will be prompted based on the guidelines set by your jurisdictional authorities. When a retest is required, a notification will appear on the screen, accompanied by an auditory and visual cue. Sufficient time will be provided for you to safely pull over to a designated area where you can provide the breath sample.


Blow and go devices offer numerous benefits that contribute to preventing accidents and assisting individuals in reclaiming their driving privileges. This blog post will delve into the advantages of blow and go devices. Go over their role in promoting road safety and empowering individuals on their journey towards responsible driving.

Benefits of a Blow and Go Ignition Interlock Device

  1. Preventing Drunk Driving:
    Blow and Go ignition interlock devices act as a deterrent to drunk driving by requiring individuals to provide a breath sample before starting their vehicle. This technology ensures that the driver’s blood alcohol concentration (BAC) is within legal limits, reducing the risk of impaired driving and potential accidents caused by alcohol consumption.
  2. Promoting Road Safety:
    By implementing blow and go devices, communities experience a significant improvement in road safety. These devices prevent unauthorized individuals, such as friends or family members, from operating a vehicle under the influence. With each breath sample required, blow and go devices reinforce responsible driving behavior and encourage individuals to make safer choices behind the wheel.
  3. Helping Individuals Regain Driving Privileges:
    Blow and Go ignition interlock devices also offer a path for individuals to regain their driving privileges after a DUI conviction. In many jurisdictions, these devices are mandatory for individuals with a history of drunk driving. By installing a blow and go device and demonstrating their commitment to sobriety, individuals can work towards reinstating their driving privileges, providing them with a renewed sense of independence and the opportunity to rebuild their lives.
  4. Monitoring and Accountability:
    One of the key benefits of blow and go devices is the ability to monitor and track an individual’s alcohol consumption. Regular breath samples ensure compliance with court-ordered requirements, providing a transparent record of responsible behavior. This feature not only helps individuals fulfill their legal obligations but also offers valuable data for monitoring progress and supporting counseling or treatment programs.


Blow and Go ignition interlock devices are essential in preventing drunk driving and assisting individuals in regaining their driving privileges. By requiring breath samples, these devices act as a deterrent. They ensure that drivers are sober and capable of operating a vehicle safely.
