Refusing a Breathalyzer in Massachusetts
Massachusetts, like all U.S. states, has an implied consent law. By driving on Massachusetts 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 Massachusetts
Different states use different terminology. Massachusetts uses DUI (Driving Under the Influence) as its primary statute, though both alcohol and drug impairment can result in charges.
