Elements that Worsen a DUI Charge
While a basic first-time DUI is a misdemeanor, prosecutors aggressively pursue enhancements that drastically raise fines, enforce mandatory jail time, and suspend licenses for longer periods.
- High BAC: A Blood Alcohol Content over 0.15% (or 0.20% in some states) triggers mandatory enhancements.
- Minors in Vehicle: Child endangerment charges are often added.
- Property Damage/Injury: Elevates a standard DUI to an "Aggravated DUI" or a felony.
- Prior DUIs: Lookback periods (usually 7 to 10 years) dictate whether you are charged as a repeat offender. A 3rd or 4th DUI is almost always charged as a felony.
Important Legal Disclaimer
A DUI conviction involves DMV administrative actions, skyrocketing insurance premiums, court probation fees, and alcohol classes. The true cost of a DUI is often $10,000+. Hire a local criminal defense attorney focused on DUI law.
