  • A.30 days.
  • B.90 days.
  • C.6 months.
  • D.1 year.✓

Why: According to Chapter 8 of the manual, penalties increase for repeat offenses. If you are convicted of a second or subsequent DUI within a five-year period, the mandatory suspension period is one year.

  • A.90 days.
  • B.6 months.
  • C.1 year.✓
  • D.2 years.

Why: If a driver under 21 is convicted of driving with a BAC of 0.02% or higher for the third time, their license will be suspended for one year. The official manual states that while a first conviction results in a six-month suspension, penalties for subsequent convictions are "much worse."

5
