Any person who operates an aircraft in this state is considered to have given his or her consent by the operation thereof to a preliminary breath analysis and a secondary chemical test of either his or her blood, breath or urine for the purposes of determining the alcoholic content of his or her blood. A preliminary breath analysis may be administered in accordance with the provisions of section eleven-b of this article whenever a law-enforcement officer has reasonable cause to believe a person to have committed an offense prohibited by section eleven of this article. A secondary test of blood, breath or urine shall be incidental to a lawful arrest and shall be administered at the direction of the arresting law-enforcement officer having reasonable grounds to believe the person to have committed an offense prohibited by said section. The law-enforcement agency by which the law-enforcement officer is employed shall designate which one of the aforesaid secondary tests shall be administered: Provided, That if the test so designated is a blood test and the person so arrested refuses to submit to the blood test, then the law-enforcement officer making the arrest shall designate in lieu thereof either a breath or urine test to be administered.

For the purpose of this article, the term "law-enforcement officer" means and is limited to: (1) Any member of the State Police; (2) any sheriff and any deputy sheriff of any county; (3) any member of a police department in any municipality as defined in section two, article one, chapter eight of this code; and (4) any natural resources police officer of the Division of Natural Resources. If any municipality or the Division of Natural Resources does not have available to its law-enforcement officers the testing equipment or facilities necessary to conduct any secondary test which a law-enforcement officer may administer under this article, any member of the West Virginia State Police, the sheriff of the county wherein the arrest is made or any deputy of the sheriff or any municipal law-enforcement officer of another municipality within the county wherein the arrest is made may, upon the request of the arresting law-enforcement officer and in his or her presence, conduct a secondary test and the results of the test may be used in evidence to the same extent and in the same manner as if the test had been conducted by the arresting law-enforcement officer. Only the person actually administering or conducting the test is competent to testify as to the results and the veracity of the test.
