Do I have to do field sobriety tests for a DUI stop in Pennsylvania?

The short answer is NO—you are not required to perform field sobriety tests in Pennsylvania, and there are no legal penalties for refusing to do so.

Many drivers mistakenly believe they must comply with field sobriety tests, but under Pennsylvania law, these tests are voluntary. However, police officers are trained to persuade drivers to take them. They may say things like, “If you pass, I’ll let you go,” or “If you’re not impaired, prove it by taking the tests.” Remember, these are tactics to gather evidence, not legal requirements.

Why Do Police Use Field Sobriety Tests?

To arrest someone for Driving Under the Influence (DUI) in Pennsylvania, police must have probable cause. If you perform poorly on field sobriety tests, that provides the officer with more evidence to justify an arrest and require chemical testing (breath or blood tests) for alcohol or drugs.

Pennsylvania’s Implied Consent Law

Many drivers confuse field sobriety tests with the Pennsylvania’s Implied Consent Law, which is very different.

Under Implied Consent, any licensed driver in Pennsylvania automatically agrees to submit to blood or breath testing to measure blood alcohol concentration (BAC) — but only if the officer has probable cause to believe the driver was impaired.

Refusing a blood or breath test can lead to severe consequences, including:
✅ Automatic suspension of your Pennsylvania driver’s license
✅ Additional penalties on top of DUI charges

Importantly, field sobriety tests are not covered under Implied Consent laws, meaning:
❌ You cannot lose your license simply for refusing field sobriety tests
❌ There are no additional legal penalties for refusing these roadside tests
