The video identifies longer mandatory minimum sentences as a major difference between first- and second-offense DUI penalties. The alcohol concentration tier affects the potential sentence.
For a second offense at a 0.08 result, the video describes a five-day minimum and substantially greater potential incarceration at higher levels or in aggravated circumstances.
A second offense can also involve a lengthy ignition interlock requirement, described in the video as generally two years. An assessment of second-offense DUI penalties must account for the specific charge and facts.
