Refusing a Breathalyzer in Pennsylvania
Pennsylvania, like all U.S. states, has an implied consent law. By driving on Pennsylvania roads, you implicitly consent to chemical testing (breath, blood, or urine) if lawfully arrested for DUI. Refusing a test will typically result in automatic license suspension, separate from any DUI conviction, and the refusal can be used against you in court.
DUI vs. DWI in Pennsylvania
Different states use different terminology. Pennsylvania uses DWI (Driving While Intoxicated) as its primary statute, though both alcohol and drug impairment can result in charges.
