Will I Go to Jail for a Second DUI in Pennsylvania?Everyone makes poor decisions from time to time but driving under the influence (DUI) of drugs or alcohol is one mistake not easily excused by law enforcement in Pennsylvania. Prosecutors have been pursuing more complex ways to penalize DUIs to prevent others from making the same mistakes. As a result, drivers who have been charged with a second DUI have much more at stake with increased penalties than those of a first offense.

If you’re facing charges for a second DUI in Pennsylvania, one question that is likely top of mind is whether you may go to jail. In short, the answer is yes. However, the specific details of your case will have a significant impact on the penalties. Keep reading to learn everything you need to know.

Overview of Pennsylvania’s Drunk Driving Laws 

In Pennsylvania, penalties for driving under the influence are classified according to the driver’s blood alcohol content (BAC) along with their record of prior DUI offenses. 

Pennsylvania passed Act 23 into legislation in 2003, which created a tiered approach towards DUI enforcement while lowering alcohol’s legal limit to .08. This law created the following tiers regarding DUIs: 

  • General Impairment: BAC of .08 to .099 
  • High BAC: .10 to .159 BAC
  • Highest BAC: .16 and higher BAC

Consequently, any driver arrested for a DUI with a BAC of .08 or higher can be charged with drunk driving. At the same time, certain individuals confront enhanced penalties regardless of the type of DUI in which they’re categorized.

Drivers Who Face Heightened Penalties for Drunk Driving

Individuals who may face harsher penalties even with a general impairment DUI charge involve: 

  • Commercial drivers
  • Drivers who cause injury to others: or to property
  • Drivers who refuse to take a chemical test
  • School-employed drivers
  • Underage drivers

What’s Considered a “Second Offense” DUI in Pennsylvania?

A first offense DUI is a misdemeanor in Pennsylvania that carries penalties that include jail time, fines, and a potential loss of license. Pennsylvania’s “look back” period is ten years, meaning that any convictions for drunk driving during this time frame will be counted. 

In other words, if you’re arrested for driving under the influence within ten years of a prior DUI conviction, you can face harsher penalties that may include fines that reach the tens of thousands of dollars and a loss of driving privileges that may last for years. 

Penalties of a Second-Time DUI Offense in Pennsylvania 

All second offense DUI charges in Pennsylvania are punishable by the following consequences. Further, convicted drivers must attend and complete a court-appointed Alcohol Highway Safety School and install an Ignition Interlock Device (IID) into their vehicles before getting their driving privileges restored. If you’re convicted of a second DUI, you may also have to perform community service and receive drug and alcohol treatment. 

Below are the penalties for the various tiers of a second DUI offense.
