Pennsylvania’s DUI laws impose strict penalties based on a driver’s prior offenses and the circumstances of the arrest. Second-time DUIs result in higher fines, longer jail time, and extended license suspensions.
Penalties Based on BAC Level for Second DUIs
Pennsylvania assigns DUI penalties based on a person’s blood alcohol content (BAC) at the time of arrest. A driver with one prior DUI offense faces increasing penalties as their BAC level rises.
A second-time “general impairment” DUI with a BAC between .08 and .099 is an ungraded misdemeanor. The penalties for this level of a second DUI offense include:
- A 12-month license suspension
- Five days to six months in jail
- $300 to $2,500 in fines
- Mandatory attendance at an alcohol highway safety school
- The possibility of court-ordered treatment
- Mandatory installation of an ignition interlock device (IID) for one year
A “high BAC” DUI with one prior offense and a BAC between .10 and .159 is also an ungraded misdemeanor. The penalties for this level of a second DUI offense include:
- A 12-month license suspension
- Thirty days to six months in jail
- $750 to $5,000 in fines
- Mandatory attendance at an alcohol highway safety school
- The possibility of court-ordered treatment
- Mandatory installation of an ignition interlock device (IID) for one year
A “highest BAC” DUI with one prior offense and a BAC between .10 and .159 is a first-degree misdemeanor. The penalties for this level of a second DUI offense include:
- An 18-month license suspension
- Ninety days to five years in jail
- $1,500 to $10,000 in fines
- Mandatory attendance at an alcohol highway safety school
- The possibility of court-ordered treatment
- Mandatory installation of an ignition interlock device (IID) for one year
Drivers who refuse chemical testing can face the same penalties as those in the highest BAC category.
Additional Consequences of a Second DUI
A second DUI in Pennsylvania can create serious long-term problems beyond legal penalties. For instance, a conviction can increase car insurance rates and could lead to policy cancellation. Employers might deny job opportunities, especially in fields that require driving or professional licenses. A DUI record can also affect housing applications and financial opportunities. Courts sometimes require alcohol treatment for DUI offenders, which adds costs and time commitments. These consequences can follow a person for years, making it harder to rebuild stability after a conviction.
How a DUI Lawyer Can Help
A DUI lawyer can defend you against DUI charges and work to reduce potential penalties. They can challenge traffic stops, breath test results, and other evidence. They can negotiate for reduced charges or alternative sentencing, such as probation instead of jail. If necessary, they can also represent you at trial. Additionally, your attorney can help with license reinstatement and guide you through ignition interlock requirements. They can explain your legal options and identify relevant deadlines to help you avoid missed opportunities for defense. Their knowledge of Pennsylvania DUI laws can substantially improve your chances of a better outcome.
