What might happen during a second DUI arrest in some jurisdictions?

In many jurisdictions, a second DUI arrest can lead to the mandatory installation of an ignition interlock device. This device is designed to prevent a vehicle from starting if the driver has a blood alcohol concentration above a predetermined threshold. The installation of an ignition interlock is a common consequence for repeat offenders, intended to promote safer driving behavior and reduce the likelihood of future offenses.

This response reflects an understanding of how laws aim to deter impaired driving by adding restrictions to those who have previously violated these laws. The ignition interlock device serves not only as a punishment but also as a safeguard to protect the public by ensuring that individuals who have been convicted of DUI do not operate a vehicle under the influence again without compliance.
