implied consent statutes

State implied consent statutes criminalizing a person’s refusal to take a warrantless chemical blood alcohol test upon suspicion of drunk driving are constitutional, argues the State and Local Legal Center (SLLC) in a Supreme Court amicus brief.

All 50 states have adopted implied consent laws requiring motorists as a condition of driving in the state to consent to a blood alcohol content (BAC) test if they are suspected of drunk driving. If motorists refuse to consent typically their driver’s license is temporarily suspended. NCSL reports that 15 states also currently criminalize refusal to consent. Criminal penalties typically include fines and jail time.
