S.C. Code Ann. § 56-1-286
(C) A law enforcement officer who has arrested a person under the age of twenty-one for a violation of Chapter 5 of this title (Uniform Act Regulating Traffic on Highways), or any other traffic offense established by a political subdivision of this State, and has probable cause to believe that the person under the age of twenty-one has consumed alcoholic beverages and driven a motor vehicle may order the testing of the person arrested to determine the person's alcohol concentration.
A law enforcement officer may detain and order the testing of a person to determine the person's alcohol concentration if the officer has probable cause to believe that a motor vehicle is being driven by a person under the age of twenty-one who has consumed alcoholic beverages.
(D) A test must be administered at the direction of the primary investigating law enforcement officer. At the direction of the officer, the person first must be offered a breath test to determine the person's alcohol concentration. If the person physically is unable to provide an acceptable breath sample because he has an injured mouth or is unconscious or dead, or for any other reason considered acceptable by licensed medical personnel, a blood sample may be taken. The breath test must be administered by a person trained and certified by the State Law Enforcement Division, using methods approved by the division. The primary investigating officer may administer the test if the person's conduct during the twenty-minute pre-test waiting period is videotaped pursuant to Section 56-5-2953(A)(2)(d). Blood samples must be obtained by physicians licensed by the State Board of Medical Examiners, registered nurses licensed by the State Board of Nursing, or other medical personnel trained to obtain these samples in a licensed medical facility. Blood samples must be obtained and handled in accordance with procedures approved by the division. The division shall administer the provisions of this subsection and shall promulgate regulations necessary to carry out its provisions. The costs of the tests administered at the direction of the officer must be paid from the general fund of the State.
The person tested or giving samples for testing may have a qualified person of his choice conduct additional tests at the person's expense and must be notified in writing of that right. A person's request or failure to request additional blood tests is not admissible against the person in any proceeding. The failure or inability of the person tested to obtain additional tests does not preclude the admission of evidence relating to the tests or samples taken at the direction of the officer. The officer must provide affirmative assistance to the person to contact a qualified person to conduct and obtain additional tests. Affirmative assistance shall, at a minimum, include providing transportation for the person to the nearest medical facility which provides blood tests to determine a person's alcohol concentration. If the medical facility obtains the blood sample but refuses or fails to test the blood to determine the person's alcohol concentration, SLED must test the blood and provide the result to the person and to the officer. Failure to provide affirmative assistance upon request to obtain additional tests bars the admissibility of the breath test result in any judicial or administrative proceeding.
(F) If a person refuses upon the request of the primary investigating officer to submit to chemical tests as provided in subsection (C), the department must suspend his license, permit, or any nonresident operating privilege, or deny the issuance of a license or permit to him for:
(G) If a person submits to a chemical test and the test result indicates an alcohol concentration of two one-hundredths of one percent or more, the department must suspend his license, permit, or any nonresident operating privilege, or deny the issuance of a license or permit to him for:
(I) A test may not be administered or samples taken unless the person has been informed in writing that:
(5) he must enroll in an Alcohol and Drug Safety Action Program within thirty days of the issuance of the notice of suspension if he does not request an administrative hearing or within thirty days of the issuance of notice that the suspension has been upheld at the administrative hearing.
The primary investigating officer must notify promptly the department of the refusal of a person to submit to a test requested pursuant to this section as well as the test result of any person who submits to a test pursuant to this section and registers an alcohol concentration of two one-hundredths of one percent or more. The notification must be in a manner prescribed by the department.
(K) Within thirty days of the issuance of the notice of suspension the person may:
(2) request an administrative hearing.
At the administrative hearing if:
(O) An administrative hearing must be held within thirty days after the request for the hearing is received by the Division of Motor Vehicle Hearings. If the Division of Motor Vehicle Hearings does not hold the hearing within thirty days, the Division of Motor Vehicle Hearings must issue a written order within thirty days stating the reasons why the hearing was not held within thirty days and providing a schedule date for the hearing. If the Division of Motor Vehicle Hearings does not issue a written order within thirty days or fails within thirty days to notify the person of a new hearing date, the person shall have his driver's license, permit, or nonresident operating privilege reinstated. The scope of the hearing is limited to whether the person:
(4) consented to taking a test pursuant to this section, and the:
(d) the machine was operating properly.
Nothing in this section prohibits the introduction of evidence at the administrative hearing on the issue of the accuracy of the breath test result.
A written order must be issued to all parties either reversing or upholding the suspension of the person's license, permit, or nonresident's operating privilege, or denying the issuance of a license or permit within thirty days after the conclusion of the administrative hearing. If the suspension is upheld, the person must receive credit for the number of days his license was suspended before he received a temporary alcohol restricted license and requested the administrative hearing.
