Why do you need an Interlock?

If you've received a DUI or DWI conviction, it's probable that you'll be required to install an ignition interlock device (IID) in your vehicle to retain certain driving privileges. Whenever your license is suspended, obtaining an IID-restricted license becomes necessary. Although the titles and eligibility criteria vary by state, the prospect of installing an ignition interlock device might feel daunting. This is completely understandable, but rest assured. We have dedicated efforts to create some of the most advanced yet user-friendly devices available, including the compact WR3 handset.

How to use the WR3 Interlock

The WR3 is straightforward in operation. Follow the on-screen prompts to know when to blow into the device. Then, provide a steady breath for four to five seconds. Subsequently, the device will indicate if you've passed. If successful, you'll be instructed to start your car. All data is stored in the device and can be downloaded if needed. Random testing intervals, as determined by your local authorities, will be prompted. The retest request will appear on the screen, accompanied by both visual and auditory cues. You'll have time to pull over to a safe location to provide the breath sample.

The WR3 grants drivers the ability to maintain certain driving privileges while ensuring public safety. Its usage is straightforward, and your service provider will equip you with a comprehensive training and compliance manual. With cutting-edge technology and a user-friendly interface, the WR3 combines science with practicality. For more information, contact us.
