Final Answer:
The purpose of an ignition interlock device is to prevent a vehicle from starting if the driver has consumed alcohol (Option 3). This technology is rooted in the critical need to address the serious and potentially life-threatening issue of driving under the influence. By incorporating a breathalyzer test into the ignition process, the device acts as a proactive measure to ensure that individuals with elevated levels of alcohol in their system are unable to operate a vehicle, thereby significantly reducing the risk of accidents and promoting overall road safety.
Step-by-step explanation:
The primary purpose of an ignition interlock device (IID) is to prevent a vehicle from starting if the driver has consumed alcohol. This device is typically installed in the vehicle of individuals who have been convicted of driving under the influence (DUI) or driving while intoxicated (DWI) offenses.
The IID requires the driver to blow into a breathalyzer to measure their blood alcohol concentration (BAC). If the detected BAC is above a predetermined limit, the device prevents the vehicle from starting, promoting road safety and preventing impaired driving.
Installing ignition interlock devices is a preventive measure aimed at reducing the risks associated with alcohol-impaired driving. It ensures that individuals with a history of DUI or DWI offenses are not able to operate a vehicle if they have consumed alcohol. This technology has been effective in curbing repeat offenses and contributing to overall road safety.
Options 1, 2, and 4 do not align with the primary function of an ignition interlock device. Forgetting the keys (Option 1), having a valid license (Option 2), or having a full tank of gas (Option 4) are not criteria for the device to prevent the vehicle from starting. The central focus is on monitoring the driver's alcohol consumption to enhance public safety on the roads.
So correct option is Option 3: Consumed alcohol.
