How long must an interlock device be installed for a first DWI offense?

For a first DWI offense, the interlock device is typically required to be installed for a period of one year. This requirement serves as a measure to prevent future incidents of driving while impaired, as it allows individuals to drive legally only when their blood alcohol concentration is below a certain limit. The installation of the interlock device can help reinforce responsible behavior and promote safe driving practices after an individual has faced legal consequences for a DWI.

When installed, the device must be calibrated and monitored regularly to ensure compliance. This one-year requirement reflects the legal framework designed to address first-time DWI offenses, balancing the need for public safety with opportunities for rehabilitation.
