What are the penalties for a conviction of a third offense DUI (General Impairment)?
A third-offense DUI conviction at the General Impairment tier in Pennsylvania — meaning a BAC between 0.08% and 0.099% and two prior DUI offenses within the previous 10 years — represents a significant escalation in penalty compared to first and second offenses, with mandatory jail time and a criminal record at the misdemeanor level.
What Constitutes a Third Offense at General Impairment
To be sentenced as a third offense at the General Impairment tier, the current BAC must fall between 0.08% and 0.099% (or the driver must be otherwise impaired to any degree), and there must be at least two prior DUI convictions or ARD completions within the 10 years preceding the date of the current offense. Both priors must fall within the 10-year lookback window established by 75 Pa. C.S. § 3806.
Statutory Penalties
A third-offense General Impairment DUI is graded as a Misdemeanor 1 under Pennsylvania law and carries the following penalties upon conviction:
- Mandatory minimum imprisonment: 10 days
- Maximum imprisonment: 2 years
- Mandatory minimum fine: $500
- Maximum fine: $5,000
- License suspension: 12 months
- Mandatory alcohol highway safety school
- Drug and alcohol treatment as ordered by the court
No ARD or Diversion Available
ARD and similar diversion programs are not available for third DUI offenses in Pennsylvania. The defendant must face the full criminal process, and upon conviction, the mandatory minimum sentence of 10 days imprisonment applies — meaning the sentencing judge has no discretion to impose less than 10 days of actual incarceration. This mandatory minimum is served consecutively to any other sentence being served at the time.
How Third-Offense Treatment Compares to Lower Tiers
The General Impairment tier carries the lowest mandatory minimums among third-offense DUI charges — but it is still a Misdemeanor 1 with mandatory jail time. Compare this to third-offense High Rate and Highest Rate DUIs, which can be graded as Felony 3 and carry mandatory minimums of one year imprisonment. The difference in BAC measurement between tiers can therefore have a dramatic effect on the severity of the mandatory sentence, making accurate BAC measurement and potential challenges to the testing methodology critically important in third-offense cases.
Sentencing Considerations
While the mandatory minimum establishes a floor, the sentencing judge retains discretion within the statutory maximum. Factors that courts in Erie County and across Pennsylvania consider in DUI sentencing include the defendant’s cooperation with authorities, participation in treatment programs, employment and family circumstances, the circumstances of the specific offense, and any evidence of steps taken toward rehabilitation. A strong mitigation presentation by defense counsel can affect where within the statutory range the sentence ultimately falls.
License and Ignition Interlock
The 12-month license suspension for a third General Impairment conviction is imposed by the court and reported to PennDOT. Pennsylvania law also requires ignition interlock as a condition of license restoration for repeat DUI offenders. The specific ignition interlock period is determined based on the offense history and applicable regulations.
