Pennsylvania DUI Laws (All You Need to Know)

Sadly, drunk driving is still a big problem across the US. 

It has caused so many crashes. 

Inflicted so many injuries. 

Taken away so many lives. 

It’s in your best interest to avoid this.

Not only that but, in Pennsylvania, it’s illegal to drive under the influence. 

And you know what that means?

Even if you don’t get into an accident, you can still face harsh penalties if you’re caught. 

That’s what we’re going to look at here — all the Pennsylvania DUI laws and their penalties, as well as the Driver License Compact (DLC). 

There’s so much to cover, so let’s begin right away!

DUI Laws in Pennsylvania

Pennsylvania drunk driving

Now, there are several laws that talk about DUIs. 

These include:

  • Illegal BAC levels
  • Zero tolerance law
  • Drugged driving
  • Implied consent law
  • Underage drinking
  • Open container law
  • Daena’s Law

Let’s look at all of these in detail. 

Illegal BAC Levels

What is driving under the influence in Pennsylvania?

Well, according to the law, you are considered a DUI if your blood alcohol concentration (BAC) reaches these percentages: 

  • 0.08% for drivers aged 21 and above
  • 0.04% for drivers with commercial licenses
  • 0.02% for drivers below 21 years old

BAC levels are determined by a breath, blood, or urine test. 

That said, you can still be charged with DUI even if your BAC is below these levels. This is if you show signs of drunkenness, such as weaving, going over the speed limit, going very slowly, or disobeying traffic signals. 

Remember, alcohol affects people in different ways — some only need a little alcohol in their system to already be drunk. 

Zero Tolerance Law

You might be wondering why drivers below 21 years old have it bad. 

I mean, 0.02% is only one glass. 

This is because of Pennsylvania’s zero-tolerance law. 

Did you know that it’s NOT legal to drink until you reach 21 years old?

So any measurable amount of alcohol in their system is a big NO NO.

Even more so if they get behind the wheel. 

As you might expect, the penalties are severe. 

For example, your first offense will already get you some jail time from 2 days to 6 months. On top of that, your license is suspended for a year and you need to pay a fine of $500 – $5,000. 

Drugged Driving

A DUI doesn’t just mean alcohol.

Drugs can impair your driving, too. 

So if you show signs of driving under the influence, and there is any amount of drugs found in your system, you will be charged with DUI. 

And yes, that applies even if you just took over-the-counter or prescription drugs. 

This is why it’s very important to know the effects of the drugs you take.

And if the effects impair your driving, you should NOT get behind the wheel. 

Implied Consent Law

As we said, you need to take a breath, blood, or urine test to check your BAC level. 

Now, under the Implied Consent Law, you HAVE to submit to these tests. 

Implied consent means that, once you get your PA driver’s license, you agree to this consent. 

And if you refuse to take the test, you will face these penalties: 

  • License suspension for one year.
  • Additional suspension for a conviction (if proven DUI) or take an Accelerated Rehabilitative Disposition (ARD) Program. 
  • Chemical test refusal restoration fee ($500 for the first offense, $1,000 for the second, and $2,000 for the third).

Of course, if you feel that the chemical test was not necessary, you can hire a DUI attorney to fight back.

Open Container Law 

The Open Container Law states that…

“All drivers and passengers are NOT allowed to have an open container of any alcoholic beverage in the motor vehicle.” 

However, there are exceptions:

  • If the vehicle is used for hire to transport passengers and the passengers have an open container of alcohol (like a limousine party). 
  • If the individual is in the living quarters of the vehicle (house coaches or trailers).
  • If the open container is in a place where the driver or passenger cannot reach it (in the vehicle’s trunk).

Deana’s Law

Deana’s Law imposes stricter penalties for repeat DUI offenders.

Here’s what it says:

  • It’s a third-degree felony with up to 7 years of jail time for those with two prior DUI offenses
  • It’s a second-degree felony with up to 10 years of jail time for those with three or more prior DUI offenses

This law was named after Deana Eckman.

In 2019, she was killed in a car crash by a man who had 5 DUI convictions. 

The goal of the law is to prevent drivers with multiple DUI offenses to operate motor vehicles in Pennsylvania. 

DUI Penalties in Pennsylvania 

Okay, those were all the Pennsylvania DUI laws. 

Now, let’s move on to the penalties. 

The penalties for DUI differ depending on the amount of alcohol in your system. 

It’s called levels of impairment and comes in three tiers: 

  • 0.08% – 0.099% BAC
  • 0.10% – 0.159% BAC
  • 0.16% BAC and up

Here are the penalties for 0.08% – 0.099% BAC:

1st$3006 months probationNo action
2nd$300 – $2,5005 days – 6 months in prison12-month suspension and 1-year ignition interlock requirement
3rd$500 – $5,000According to the new Deana’s Law – 7 years in prison12-month suspension and 1-year ignition interlock requirement

Here are the penalties for 0.10% – 0.159% BAC AND underage drinkers with a 0.02% BAC:

1st$500 – $5,0002 days – 6 months in prison12-month suspension and 1-year ignition interlock requirement

Finally, if your BAC is 0.16% and above, here are the penalties you will face:

1st$1,000 – $5,0003 days – 6 months in prison12-month suspension and 1-year ignition interlock requirement
2nd$1,50090 days – 5 years in prison18-month suspension and 1-year ignition interlock requirement
3rd At least $2,500According to the new Deana’s Law – 7 years in prison18-month suspension and 1-year ignition interlock requirement

The more DUI offenses you pile up, the harsher the penalties become. 

Driver License Compact (DLC)

The State of Pennsylvania is part of the Driver License Compact (DLC).

This is a compact between member states wherein there is a “one driver’s license” and “one driver’s record” concept. 

By “one driver’s license”, the person who has an out-of-state license should surrender it to their new state of residence so they can get a new license. 

The “one driver’s record”, on the other hand, means that the driver’s record is maintained regardless of the state where the driver resides. 

So if DUI offenses are committed out-of-state, those offenses are treated as if they were done in Pennsylvania or any other member state.
