If you’re stopped for suspected DUI in Erie, Edinboro, or Crawford County, the officer may ask you to perform a field sobriety test. In a stressful moment like this, one question becomes crucial: Are field sobriety tests mandatory in Pennsylvania?

The short answer is no—you are not legally required to take them. Still, the decision to refuse can affect what happens next. Let’s explore what field sobriety tests are, when they’re used, and how they relate to your rights under Pennsylvania law.

What Are Field Sobriety Tests and How Are They Used?

Field sobriety tests (FSTs) are roadside exercises designed to help police officers detect signs of impairment. These tests evaluate balance, coordination, and the ability to follow instructions.

The three standard tests approved by the National Highway Traffic Safety Administration (NHTSA) include:

  • Horizontal Gaze Nystagmus (HGN): Checks for involuntary eye movement.
  • Walk-and-Turn: Assesses balance and divided attention.
  • One-Leg Stand: Tests physical coordination.

While these tests are commonly used, they are also subjective. Officers may misinterpret poor performance caused by medical issues, nervousness, or fatigue. You can learn more about how these tests are administered on the NHTSA’s field sobriety testing page.

Are Field Sobriety Tests Mandatory During a DUI Stop in Pennsylvania?

In Pennsylvania, field sobriety tests are voluntary. You are under no legal obligation to perform them during a traffic stop. Unlike chemical tests (such as breath or blood tests), field sobriety tests do not fall under the state’s implied consent law.

This means that:

  • You may politely refuse without facing automatic penalties.
  • Your refusal does not result in license suspension by itself.
  • Police may still proceed based on other observations.

For more information on DUI laws and consent in Pennsylvania, the PennDOT DUI resource page explains how chemical testing works under state law. You can view it at penndot.pa.gov.

What Happens If You Refuse a Field Sobriety Test?

If you choose not to take a field sobriety test in Erie, Edinboro, or Crawford County, the officer may still arrest you—especially if they observe other signs of intoxication such as:

  • Slurred speech
  • Bloodshot eyes
  • Alcohol odor
  • Unsteady driving

Although refusal won’t lead to immediate penalties, it can still be used against you in court. Prosecutors may argue that your refusal suggests you were trying to hide impairment. Still, refusing an FST limits the amount of evidence collected against you, which may benefit your defense later.

Should You Refuse Field Sobriety Tests During a Pennsylvania DUI Stop?

Many DUI defense attorneys recommend refusing field sobriety tests, and here’s why:

  • The tests are not always reliable.
  • You could fail even if you’re completely sober.
  • Officers often use the results to justify a DUI arrest they already planned to make.

If you’re unsure how to respond during a stop, it’s best to remain calm and say something like, “I respectfully decline to take any field tests.”

Every case is different, so if you’re arrested, contact a local DUI attorney immediately to discuss your options.

Are Field Sobriety Tests Required After Arrest in Pennsylvania?

It’s essential to separate field sobriety tests from chemical tests. Once you’re arrested for DUI, Pennsylvania’s implied consent law kicks in. This law requires you to submit to a breath or blood test, and refusing one does carry penalties, including:

  • Automatic license suspension
  • Enhanced criminal penalties
  • Use of the refusal as evidence in court

Understanding the difference between field tests (voluntary) and chemical tests (mandatory after arrest) can make a significant impact on your case.
