The U.S. Supreme Court made several rulings on Thursday and one of those directly impacts Indiana.
The ruling deals with blood tests to measure blood alcohol content (BAC).
The justices ruled that those suspected of drunk driving can refuse a blood test without running the risk of additional charges if police fail to obtain a warrant.
As it stands now, law enforcement officers only need a warrant if the driver refuses to take the blood test which is done at the hospital.
In that case, the driver would likely be charged with obstruction of justice.
However, the ruling does not impact breathalyzers which the court considers less intrusive.
