The short answer is yes. Pennsylvania has an implied consent law. This means that anyone who obtains a driver’s license is automatically consenting to taking breath or blood tests if requested. While you can refuse to submit to such tests, there are severe penalties for doing so. If you refuse a test of this type, your driver’s license may be suspended for a period of at least one year. The refusal can also be used as an indication that you were in fact driving while intoxicated. To avoid this situation, our BAC calculator may be helpful.
