A car breathalyzer ignition interlock system, commonly referred to as an IID (Ignition Interlock Device), is a safety mechanism designed to prevent a vehicle from starting if the driver’s breath alcohol concentration (BAC) exceeds a set limit. These devices are widely used for both court-mandated DUI programs and voluntary installations by safety-conscious drivers or businesses.
How Does It Work?
An IID requires the driver to blow into a breathalyzer connected to the car’s ignition system. If the measured BAC is above the threshold (usually 0.02% or lower, depending on state laws), the vehicle will not start. Additionally, periodic retests may be required while driving to ensure continued compliance.
Why Buy or Lease an IID?
- Court-Ordered Usage: For DUI offenders, many states mandate the installation of an IID to regain driving privileges.
- Voluntary Installation: Parents of teenage drivers, families, or businesses may choose to install IIDs as a preventive measure.
- Commercial Fleet Safety: Companies with drivers on the road can reduce liability by requiring IIDs in their vehicles.
Buying vs. Leasing
- Leasing: The majority of IID users opt to lease due to lower upfront costs. Monthly fees typically range from $60–$90, depending on the provider and state regulations.
- Buying: For voluntary or long-term use, outright purchase might make sense, but professional installation and periodic calibration are still required. Leasing may remain more economical for court-mandated use.
Installation and Maintenance
- IIDs cannot be installed by the user. Certified professionals handle installation to ensure compliance with legal and safety standards.
- Regular calibration is required, usually every 30–90 days, depending on whether the device is monitored by authorities or used voluntarily.

- Costs: Beyond installation and lease fees, you may need to pay for calibrations and maintenance. Financial assistance programs are available in some cases.
- Voluntary Use: Opting for an IID voluntarily can increase safety and peace of mind for drivers and their families.
In summary, purchasing or leasing a car breathalyzer ignition interlock system is a practical choice for ensuring safety, whether mandated by law or undertaken voluntarily. Carefully consider your needs, budget, and state requirements to select the best option for your situation. For more details, you can explore.
