Lookback period
Wyoming uses a 10 years (5 years for felony threshold) Lookback period to determine how prior offenses affect sentencing. Only DUI convictions within this window count toward the escalating penalty tiers.
Enhanced penalties for aggravating factors §31-5-233(b)(ii)
- BAC ≥ 0.15 (enhanced penalties)
- Prior DUI within 10 years
- Child under 18 in vehicle
- DUI causing serious injury or death (separate felony charges)
What these penalties mean in practice
Mandatory minimums cannot be suspended or reduced by the judge — they must be served. Fines do not include surcharges, court costs, and program fees, which can substantially increase the total financial impact. License suspension affects employment, insurance rates, and daily logistics.
