Ignition Interlock

Smallest and Easiest To Use Device

The L250 Ignition Interlock is our smallest handset with the most reliable technology. It’s designed to prevent you from being able to start your vehicle until you pass the alcohol test. This vehicle ignition interlock device has an easy blow pattern (deep inhale, blow and hum a consistent tone) and a simple screen. We’ll help you navigate through the complex procedures and ensure that you are fully trained during the install process. Having an interlock device can give you the freedom to get back out on the road again. These devices are able to quickly test and detect any alcohol levels present in the driver’s breath. Whether installed following a DUI or voluntarily added as a safety feature, this device won’t let your vehicle start if it detects a specific level of alcohol. If you’re sober, you’ll be good to go.
