The correct answer reflects the consequences of failing to utilize an ignition interlock device when required. If you are obligated to have this device installed in your vehicle due to prior driving offenses, operating a vehicle without one constitutes a serious violation.

In such a case, the law typically stipulates that the vehicle may be impounded for a set period. This action is taken to enforce compliance and ensure the safety of both the driver and the public. The specified duration of seven days aligns with standard penalties for such infractions, emphasizing the importance of adhering to the regulations surrounding ignition interlock devices.

Other choices suggest less severe consequences, such as a warning or shorter impoundment periods, which does not accurately reflect the seriousness with which such violations are treated. Additionally, facing only a fine without any vehicle consequences fails to address the significant public safety concern that arises from driving without the mandated device.
