DUI - Third-Offense
Facing a 3rd DUI? Your Freedom and Future Are on the Line.
A third DUI in Pennsylvania is treated as a very serious criminal offense. Penalties include mandatory jail time, long license suspensions, steep fines, ignition interlock requirements, and a permanent criminal record.
At Sheridan Lawyers, we know how high the stakes are. Our experienced DUI defense attorneys fight aggressively to protect your rights and freedom when you are facing a third-offense DUI in Chester County, Bucks County, Delaware County, and Montgomery County, Pennsylvania.
Penalties for a Third DUI in Pennsylvania
Penalties depend on your Blood Alcohol Content (BAC) and whether drugs were involved, but a 3rd DUI typically includes:
Mandatory Jail Time: 10 days to 1 year (or longer, depending on BAC and circumstances)
License Suspension: 12 to 18 months or more
Fines: $2,500 to $10,000
Ignition Interlock Device: Required for at least 1 year after license restoration
Permanent Criminal Record: A felony under some circumstances
Treatment Programs: Alcohol safety classes, treatment, and community service
If an accident with injury or death occurred, felony DUI, aggravated assault by vehicle, or vehicular homicide charges may also be filed.
How Sheridan Lawyers Fight a 3rd DUI Charge
Challenge the Stop: Was there probable cause for the traffic stop?
Challenge the Testing: We review whether the breath, blood, or urine testing was accurate and properly administered.
Protect Your Rights: If police violated your constitutional rights, we fight to suppress evidence.
Negotiate Alternatives: We pursue reduced charges, entry into treatment-based programs, or sentencing alternatives whenever possible.
Trial Defense: If the case goes to trial, we are ready to fight for a not guilty verdict.
Why a Third DUI Is Different
With two prior DUI convictions, prosecutors and judges will treat your case much more harshly. Repeat offenders face mandatory minimums with fewer opportunities for diversion programs. That is why you need a skilled, aggressive DUI attorney from day one.
