Driving under the influence (DUI) in Pennsylvania carries serious consequences. Whether it’s your first offense or you’ve been charged before, the penalties for DUI can affect nearly every aspect of your life: your license, your job, your finances, and even your freedom.

At McGarrigle Law Firm, we understand how overwhelming it is to face DUI charges. This blog will break down the penalties for DUI in Pennsylvania, explain how the state’s tiered system works, and show why working with an experienced Pennsylvania DUI lawyer is essential to protect your future.

Understanding Pennsylvania’s Tiered DUI Penalty System

Pennsylvania doesn’t treat all DUIs the same. Instead, the state uses a tiered penalty system based on two key factors:

1. Your Blood Alcohol Concentration (BAC) at the time of arrest
2. The number of prior DUI offenses on your record
   

Here’s how the tiers are classified:

• General Impairment: BAC 0.08% – 0.099%
• High BAC: BAC 0.10% – 0.159%
• Highest BAC: BAC 0.16% or higher, or any DUI involving drugs/controlled substances
  

The higher your BAC or the more prior offenses you have the harsher the penalties.

Penalties for a First-Time DUI in Pennsylvania

Even a first DUI offense can have life-changing consequences.

• General Impairment (0.08% – 0.099% BAC):
  • No jail time for most first offenders
  • Fines up to $300
  • Mandatory alcohol highway safety school
  • Probation for up to 6 months
• High BAC (0.10% – 0.159% BAC):
  • 48 hours to 6 months in jail
  • Fines from $500 to $5,000
  • 12-month license suspension
• Highest BAC (0.16%+ or drugs):
  • 72 hours to 6 months in jail
  • Fines from $1,000 to $5,000
  • 12-month license suspension
    

Even first-time offenders may be eligible for the Accelerated Rehabilitative Disposition (ARD) program, which can reduce penalties and help avoid a permanent criminal record.

Penalties for a Second DUI in Pennsylvania

The penalties increase significantly for a second offense.

• General Impairment:
  • 5 days to 6 months in jail
  • $300–$2,500 fine
  • 12-month license suspension
  • Mandatory ignition interlock device for 1 year
• High BAC:
  • 30 days to 6 months in jail
  • $750–$5,000 fine
  • 12-month license suspension
  • Ignition interlock requirement
• Highest BAC / Drugs:
  • 90 days to 5 years in jail
  • $1,500–$10,000 fine
  • 18-month license suspension
  • Ignition interlock requirement

Penalties for a Third or Subsequent DUI in Pennsylvania

Multiple DUI convictions bring the harshest penalties under Pennsylvania law:

• General Impairment:
  • 10 days to 2 years in jail
  • $500–$5,000 fine
  • 12-month license suspension
  • Ignition interlock requirement
• High BAC:
  • 90 days to 5 years in jail
  • $1,500–$10,000 fine
  • 18-month license suspension
  • Ignition interlock requirement
• Highest BAC / Drugs:
  • 1 to 5 years in jail
  • $2,500–$10,000 fine
  • 18-month license suspension
  • Ignition interlock requirement
    

At this level, DUIs are often charged as felonies, which carry permanent consequences on your record.

Additional Consequences of a DUI Conviction

Beyond fines and jail time, DUI convictions in Pennsylvania can also lead to:

• A permanent criminal record that shows up on background checks
• Skyrocketing insurance premiums or loss of coverage
• Employment challenges, especially if your job requires driving
• Travel restrictions to certain countries with strict entry laws
  

These secondary effects are often just as damaging as the legal penalties themselves.
