An ignition interlock device (IID) functions as a breathalyzer integrated with a vehicle's ignition system, designed to prevent drunk driving. The device measures a driver's blood alcohol content (BAC) before allowing the car to start. If alcohol is detected above a predetermined limit, the ignition will not engage.
These devices may be mandated by courts for individuals with prior driving under the influence (DUI) convictions. Additionally, they can be voluntarily sought by individuals concerned about their own or a loved one's alcohol consumption before driving.
LifeSafer is one company offering such devices. Their IID is described as small and discreet, connecting to a car's ignition. The operation involves a simple breath test; if the driver passes, the vehicle starts. While the device does not stop the car mid-drive, it may prompt periodic breath tests during operation.
LifeSafer provides installation services across the United States through nearly 2,000 service centers. The company also handles device removal. According to the manufacturer, the device is designed to be easy to use and does not require complex blowing patterns.
For those court-appointed to use a breathalyzer, the LifeSafer device is presented as an accessible and accurate option. Pricing for these devices typically ranges from $50 to $150, though this is subject to change.
