You should never refuse a breath test when arrested for a DUI. In Pennsylvania, refusal of either the breathalyzer or a blood test can result in losing your license for an additional year, on top of the normal drinking and driving penalties. Worse, you could forfeit your driving rights for a year even if you’re not guilty of DUI.
A two and a half year suspension can result if you refuse to take the test and you are determined to be driving under the influence, depending on your BAC level. If you refuse testing and have a prior drinking and driving conviction you’ll receive an eighteen-month suspension for refusal plus eighteen additional months for DUI.
