This law is referred to as Implied Consent ("A person who drives a motor vehicle in this State is considered to have given consent to chemical tests of the person's breath, blood, or urine for the purpose of determining the presence of alcohol, drugs, or the combination of alcohol and drugs, if arrested for an offense arising out of acts alleged to have been committed while the person was driving a motor vehicle while under the influence of alcohol, drugs, or a combination of alcohol and drugs . . . . If the person is physically unable to provide an acceptable breath sample because the person . . . is unconscious . . . the arresting officer may request a blood sample to be taken. Any additional tests to collect other samples must be collected within three hours of the arrest. S.C. Code Ann. § 56-5-2950 (A) (Supp. 2009)).
