Interlock Device

Affordable Interlock Devices Near You in Fort Worth, TX

If you’re facing a DUI charge, your state alcohol monitoring authority might require you to install an Ignition Interlock Device (IID) on your vehicle. Also known as a “car breathalyzer” or “blow-and-go,” an IID prevents your vehicle from starting if the driver’s breath sample contains alcohol over a set limit. The alternative is often a suspended license and no ability to drive—so for many drivers, an IID is the clear choice for putting your DUI behind you.

Smart Start IIDs are designed to be discreet, reliable, and simple to use:

  • Low-profile design no bigger than your smartphone
  • Rigorously tested and calibrated to match your program requirements
  • User-friendly breath testing patterns make it easy to get going

An Ignition Interlock Device (IID) prevents a vehicle from starting if it detects alcohol on the driver’s breath. The driver blows into the device, and if their breath alcohol content is below the programmed limit, the car will start. You’ll also have to complete periodic retests after starting your vehicle to ensure continued compliance. Learn more about how IIDs work with our complete guide.

In Texas, an Ignition Interlock Device (IID) may be required after a DUI. See our complete guide for information on IID laws and more in Texas.
