(a) Any person who motors, sails, rows, commands, operates or has actual physical control of a vessel or boat underway on the waters of this State shall be deemed to have given consent, subject to this section and § 2302 of this title, to a chemical test or tests of the person’s blood, breath and/or urine for the purpose of determining the presence of alcohol or a drug or drugs. The testing may be required of a person when an officer has probable cause to believe the person is in violation of § 2302 of this title or a local ordinance substantially conforming thereto.

(b) At the time that a chemical test specimen is required, the person may be informed that if testing is refused, the person shall be prohibited from operating a vessel upon Delaware’s waters for a period of 1 year.

(c) If there are reasonable grounds to believe that there is impairment by a drug or drugs which are not readily subject to detection by a breath test, a blood and/or urine test may be required even after a breath test has been administered.

(d) Alternative tests; physical incapacity. — If for any reason a person is physically unable to supply enough breath or complete the chemical test, the person shall submit to other chemical tests as designated by the officer, subject to the requirements of subsection (a) of this section. Any person who is unconscious or who is otherwise in a condition rendering the person incapable of refusal shall be deemed to not have withdrawn the consent provided in this section and any test may be performed as provided in subsection (a) of this section.

(e) Refusal to submit as admissible evidence. — Upon any trial of any action or proceeding arising out of the acts alleged to have been committed by any person while in violation of § 2302 of this title, the court may admit evidence of the refusal of such person to submit to a chemical test of the person’s breath, blood or urine.

(f) Admissibility in evidence of results of chemical test. — For purposes of a conviction premised upon § 2302(a) of this title or any proceeding pursuant to this code in which an issue is whether a person was operating a vessel while under the influence, evidence establishing the presence and concentration of alcohol or drugs in the person’s blood, breath or urine shall be relevant and admissible. Such evidence may include the results from tests of samples of the person’s blood, breath or urine taken within 4 hours of operating the vessel or at some later time. In any proceeding, the resulting alcohol or drug concentration reported when a test, as defined in § 2301(b) of this title, is performed shall be deemed to be the actual alcohol or drug concentration in the person’s blood, breath or urine without regard to any margin of error or tolerance factor inherent in such tests.

(g) Evidence of an alcohol concentration of 0.05 or less in a person’s blood, breath or urine sample taken within 4 hours of operating a vessel and tested as defined in § 2301(b) of this title is prima facie evidence that the person was not under the influence of alcohol within the meaning of this chapter. Evidence of an alcohol concentration of more than 0.05 but less than 0.08 in a person’s blood, breath or urine sample taken within 4 hours of operating a vessel and tested as defined in § 2301(b) of this title shall not give rise to any presumption that the person was or was not under the influence of alcohol, but such fact may be considered with other competent evidence in determining whether the person was under the influence of alcohol.

(h) Evidence obtained through a preliminary screening test of a person’s breath in order to estimate the alcohol concentration of the person at the scene of a stop or other initial encounter between a law-enforcement officer and the person shall be admissible in any proceeding to determine whether probable cause existed to believe that a violation of this Code has occurred. However, such evidence shall not be admissible in the determination of guilt under this section.

(i) Nothing in this section shall preclude conviction of an offense defined in this chapter based solely on admissible evidence other than the results of a chemical test of a person’s blood, breath or urine to determine the concentration or presence of alcohol or drugs.

(j) A jury shall be instructed by the court in accordance with the applicable provisions of this section in any proceeding pursuant to this chapter in which an issue is whether a person was operating a vessel while under the influence.

(k) For the purpose of introducing evidence of a person’s alcohol concentration pursuant to this section, a report signed by the Forensic Toxologist, Forensic Chemist or State Police Forensic Analytical Chemist who performed the test or tests as to its nature is prima facie evidence, without the necessity of the Forensic Toxologist, Forensic Chemist or State Police Forensic Analytical Chemist personally appearing in court:

(1) That the blood delivered was properly tested under procedures approved by the Division of Forensic Science or the Delaware State Police Crime Laboratory;

(2) That those procedures are legally reliable;

(3) That the blood was delivered by the officer or persons stated in the report; and

(4) That the blood contained the alcohol therein stated.

(l) (1) Any report introduced under subsection (k) of this section must:

a. Identify the Forensic Toxologist, Forensic Chemist or State Police Forensic Analytical Chemist as an individual certified by the Division of Forensic Science, the Delaware State Police Crime Laboratory or any county or municipal police department employing scientific analysis of blood, as qualified under standards approved by the Division of Forensic Science or the Delaware State Police Crime Laboratory to analyze the blood;

b. State that the person made the analysis of the blood under the procedures approved by the Division of Forensic Science or the Delaware State Police Crime Laboratory; and

c. State that the blood, in the person’s opinion, contains the resulting alcohol concentration within the meaning of this chapter.

Nothing in this section precludes the right of any party to introduce any evidence supporting or contradicting the evidence contained in the report entered pursuant to subsections (k) and (l) of this section.

(2) For purposes of establishing the chain of physical custody or control of evidence defined in this section which is necessary to admit such evidence in any proceeding, a statement signed by each successive person in the chain of custody that the person delivered it to the other person indicated on or about the date stated is prima facie evidence that the person had custody and made the delivery stated, without the necessity of a personal appearance in court by the person signing the statement, in accordance with the same procedures outlined in § 4331(3) of Title 10.

(3) In a criminal proceeding, the prosecution shall, upon written demand of a defendant filed in the proceedings at least 15 days prior to the trial, require the presence of the Forensic Toxologist, Forensic Chemist, State Police Forensic Analytical Chemist or any person necessary to establish the chain of custody as a witness in the proceeding. The chain of custody or control of evidence defined in this section is established when there is evidence sufficient to eliminate any reasonable probability that such evidence has been tampered with, altered or misidentified.

(m) The informing or failure to inform the accused concerning the implied consent provision shall not affect the admissibility of such results in any prosecution for a violation of § 2302(a) of this title.

(n) The doctor-patient privilege shall not apply to the disclosure to law-enforcement personnel nor the admissibility into evidence in any criminal proceeding of the results of a chemical test of a person’s blood, breath or urine for the purpose of determining the alcohol or drug content of the person’s blood irrespective of whether such test was done at the request of a treating physician, other medical personnel or a peace officer.
