(a) A person who drives a commercial motor vehicle within this state is deemed to have given consent, subject to provisions of Section 32-5-192, to take a test or tests of that person's blood, breath, or urine for the purpose of determining that person's alcohol concentration, or the presence of other drugs.

(b)(1) A test or tests shall be administered at the direction of a law enforcement officer, who after stopping or detaining the commercial motor vehicle driver, has probable cause to believe that driver was driving a commercial motor vehicle while having alcohol or drugs in his or her system. The law enforcement officer shall test the driver at the scene by using a field breathalyzer or other approved device, technique, or procedure approved by the Department of Forensic Sciences, or transport the driver to an appropriate facility where a chemical test by an approved method shall be administered either by the officer or at his or her direction, or both.

(2) A test or tests shall be administered at the direction of a law enforcement officer to all commercial motor vehicle drivers who are involved in any vehicular accident which results in death or physical injury requiring hospitalization or emergency medical treatment.

(c) A person requested to submit to a test as provided in subsection (a) above must be warned by the law enforcement officer requesting the test, that a refusal to submit to the test will result in that person being immediately placed out of service for a period of 24 hours and being disqualified from operating a commercial motor vehicle for a period of not less than two years under Section 32-6-49.12.

(d) If the person refuses testing, or submits to a test which discloses an alcohol concentration of 0.04 or more, the law enforcement officer shall submit a sworn report to the department certifying that the test was requested pursuant to subsection (b) and that the person refused to submit to testing, or submitted to a test which disclosed an alcohol concentration of 0.04 or more.

(e) Upon receipt of the sworn report of a law enforcement officer submitted under subsection (d), the department shall disqualify the driver from driving a commercial motor vehicle for a period of not less than two years under Section 32-6-49.12. This penalty shall be in addition to and cumulative of any other penalties imposed upon the driver under any other existing laws and shall run consecutively with any penalties for other offenses.

(f) Upon suspending the license or permit to drive or the privilege of driving a motor vehicle on the highways of this state that is given to a nonresident or any person, or upon determining that the issuance of a license or permit shall be denied to the person, the director or his or her authorized agent shall within three days of suspension notify the person in writing. Upon a request filed by the person within five days from the date of the notice of suspension or denial, the director shall schedule a hearing with notice of the hearing to be provided by certified mail to the person stating the date, time, place, and scope of the hearing. The scope of the hearing shall pertain to all of the following issues:

(1) Whether the law enforcement officer had reasonable grounds to believe the person had been driving a motor vehicle on the public highways of this state while under the influence of the substances enumerated in subsection (a).

(2) Whether the person refused to submit to the test upon request of a law enforcement officer.

(3) Whether the person was informed that his or her privilege to drive would be suspended or denied if he or she refused to submit to the test.

(g) If the suspension or determination that there should be a denial of issuance is sustained by the director or his or her authorized agent, the person whose license or permit to drive or a nonresident operating privilege has been suspended, or to whom a license or permit is denied, shall have the right to file a petition to review the final order, suspension, or denial within 30 days after the entry of the final order of suspension or denial by the director in the appropriate court to review the final order of suspension.

(h) When it has been finally determined under the procedures of this section that the privilege of a nonresident to operate a motor vehicle in this state has been suspended, the director shall give information in writing of the action taken to the motor vehicle administrator of the state of the residence of the person and to any state in which the person has a license.
