Ignition interlock devices utilize advanced sensor technology to accurately measure breath alcohol concentration. These sensors are highly sensitive and can detect even trace amounts of alcohol. Some devices also incorporate additional features, such as temperature sensors, to ensure the breath sample is from the driver, not a source like canned air.

Regular calibration and maintenance are crucial for the accurate functioning of the ignition interlock device. The device needs to be calibrated periodically by a certified technician to ensure its accuracy and reliability.

Calibration involves adjusting the device’s sensors to ensure accurate BrAC measurements. Additionally, the device records all breath tests, which can be downloaded and reviewed by authorities during monitoring sessions.

One important aspect of ignition interlock devices is the presence of rolling retests. These retests are conducted at random intervals after the vehicle has been started. The purpose of these retests is to ensure the driver remains alcohol-free throughout their journey.

When prompted, the driver must provide another breath sample within a specified time. Failure to provide a sample or exceeding the BrAC limit during a rolling retest can lead to consequences, such as sounding the vehicle’s horn or activating the lights as a warning, and potentially notifying the monitoring authority.

Overall, ignition interlock devices play a vital role in promoting road safety and preventing repeat offenses by individuals convicted of DUI or DWI offenses. By preventing the operation of a vehicle by an intoxicated driver, these devices help reduce the risk of accidents caused by impaired driving.

In summary, ignition interlock devices are breathalyzer-based systems installed in vehicles to prevent intoxicated individuals from driving. They measure the driver’s breath alcohol concentration and immobilize the vehicle if the BrAC exceeds a set limit.
