An ignition interlock device, often informally referenced in conjunction with geographic proximity queries, is a breathalyzer installed in a vehicle. It requires the driver to provide a breath sample before starting the engine. If the breath sample exceeds a pre-programmed alcohol concentration, the vehicle will not start. These devices may also require rolling retests while the vehicle is in operation.
The implementation of these devices serves as a preventative measure against impaired driving, promoting safer roadways and reducing alcohol-related accidents. Historically, ignition interlocks have been employed as a condition of license reinstatement following a DUI conviction. Their use has expanded as jurisdictions recognize their efficacy in reducing recidivism among individuals with alcohol-related driving offenses.
