When you get behind the wheel in Pennsylvania, you impliedly give consent to submit to a breathalyzer or blood alcohol test upon request by law enforcement. If you are asked to submit to a test, you can technically refuse to undergo a breath or blood test. Although refusing a test is not itself a crime, refusal to submit to a breathalyzer or blood alcohol test can have other consequences, including upping your DUI charges to the highest rate of alcohol or suspension or revocation of your driver’s license.
