MODERATE
This bill lowers the blood alcohol concentration threshold from 0.18 to 0.16 for mandatory substance use disorder evaluations and adjusts minimum jail sentences for repeat offenders. It also removes a restriction preventing third-time offenders from applying for treatment if they have previously applied, instead barring them only if they were previously ordered to complete such a program.
Scope change
The bill expands the scope of mandatory evaluations to include drivers with lower alcohol levels and modifies eligibility rules for treatment programs to allow more third-time offenders to apply.
THRESHOLDS

The blood alcohol concentration threshold requiring a substance use disorder evaluation was lowered from 0.18 to 0.16.

REQUIREMENT

The minimum term of imprisonment or residential confinement for a second DUI offense within 7 years was increased from 10 days to 20 days.

A new penalty applies to third-time offenders undergoing treatment programs who subsequently commit another DUI offense.

ELIGIBILITY

Restrictions on third-time offenders applying for treatment programs were changed; they are now only barred if previously ordered to complete treatment, rather than if they had previously applied.

DEFINITION

The definition of 'prior offense' now includes being currently undergoing a treatment program for a first, second, or third-time offender.

TECHNICAL

Several sections defining the 0.18 threshold were deleted and replaced with the new 0.16 standard throughout the text.
