(3) Is so far impaired by any drug, combination of drugs, or combination of one or more drugs and alcohol that the person cannot operate a vessel safely; or
(4) Is impaired by any controlled dangerous substance, as defined in § 5–101 of the Criminal Law Article, unless the person is entitled to use the controlled dangerous substance under the laws of the State.
(b) (1) Except as provided under paragraph (2) of this subsection, the evidentiary presumptions and procedures established under §§ 10–302 through 10–309 of the Courts Article are applicable to any violation of this section.
(2) If at the time of testing an individual has an alcohol concentration that meets the definition of “under the influence of alcohol per se” in § 11–174.1 of the Transportation Article, as determined by an analysis of the individual’s blood or breath, it shall be prima facie evidence that the individual was operating a vessel while under the influence of alcohol.
(3) Any person who operates or attempts to operate a vessel on the waters of the State is deemed to have consented, subject to §§ 10–302 through 10–309 of the Courts Article, to take a test, as defined in § 16–205.1 of the Transportation Article, if the person is detained by a police officer who has reasonable grounds to believe that the person has been operating or attempting to operate a vessel while under the influence of alcohol, while impaired by alcohol, while so far impaired by any drug, any combination of drugs, or a combination of one or more drugs and alcohol that the person could not operate the vessel safely, or while impaired by a controlled dangerous substance.

(d) It is not a defense to a charge of violating subsection (a)(3) of this section that the person charged is or was entitled under the laws of this State to use the drug, combination of drugs, or combination of one or more drugs and alcohol, unless the person was unaware that the drug or combination would make the person incapable of safely operating a vessel.
