Blood testing is an important tool for police in drunk driving cases. Motorists have certain rights when confronted with testing. But, in a Wisconsin DUI case, the U.S. Supreme Court is trying to determine whether police must seek a warrant to draw blood from an unconscious driver.
It is commonly believed that an expunged criminal conviction is erased and cannot be used against a person. However, an expunged drunk driving conviction may live to survive another day in Wisconsin. The state supreme court ruled last month that expunged convictions for drunk driving charges may be considered for later OWI convictions.
Wisconsin's implied consent law allows police to draw a suspected drunk driver's blood if they are unconscious. The state supreme court may review the legality of this law, which could be before the court in a third consecutive session.
