Final answer:
Mandatory sentences for a first-time DUI offense with a BAC over 0.08 but under 0.1 vary by state, often including a fine, license suspension, and possible jail time. Intoxication is legally defined by BAC levels, and Breathalyzers are used for measurement.
Step-by-step explanation:
The mandatory sentence for a first offense DUI (Driving Under the Influence) with a Blood Alcohol Concentration (BAC) over 0.08 but under 0.1 varies depending on the jurisdiction. Generally, for a first-time offender, the penalties can include a fine, a period of driver's license suspension, potential community service, mandatory alcohol education or treatment programs, and sometimes jail time. The severity of the sentence is influenced by the specific laws of the state and can also be affected by any aggravating circumstances surrounding the DUI offense.
Legally, alcohol intoxication is often defined as a BAC of greater than 5.4-17.4 mmol/L (25-80 mg/dL or 0.025-0.080%), measurable through blood or breath testing. A Breathalyzer is a portable device used by law enforcement to measure the ethanol concentration in a person's breath, which is directly proportional to their blood alcohol level. The consumption of alcohol can impair tasks that require skill and judgment, making it unsafe and illegal to drive when intoxicated.
