A: You are not legally required to take field sobriety tests in Pennsylvania, and you can respectfully and politely decline to take them. However, you are required to take chemical tests to determine your blood alcohol concentration ("BAC") A chemical test requires you to give a blood, breath, or urine sample. The type of sample you must give is up to the police officer. If you refuse to take a chemical test, there are serious consequences, such as the loss of your driver's license. Remember always be polite and courteous to the officer. Read more about the consequences of refusing a blood test in The Basics: For Anyone Arrested for DUI in Pennsylvania at page 33.
