May a police officer use force on a person to make him take a breath or blood test?
Sometimes for blood, but never for breath. An officer has authority to order a blood sample from an arrested person only if he obtains a valid warrant; or without a warrant if there has been an accident where a death has resulted, a death is likely to occur, or there has been a serious bodily injury. Attorney note: A blood test is considered within the scientific community to be the most accurate form of alcohol testing.
