(1) When the person is under the influence of alcohol;

(2) When the person is under the influence of any drug;

(3) When the person is under the influence of a combination of alcohol and any drug;

(4) When the person’s alcohol concentration is .08 or more; or

(5) When the person’s alcohol concentration is, within 4 hours after the time of driving .08 or more. Notwithstanding any other provision of the law to the contrary, a person is guilty under this subsection, without regard to the person’s alcohol concentration at the time of driving, if the person’s alcohol concentration is, within 4 hours after the time of driving .08 or more and that alcohol concentration is the result of an amount of alcohol present in, or consumed by the person when that person was driving;

(6) When the person’s blood contains, within 4 hours of driving, any amount of an illicit or recreational drug that is the result of the unlawful use or consumption of such illicit or recreational drug or any amount of a substance or compound that is the result of the unlawful use or consumption of an illicit or recreational drug prior to or during driving.

(b) In a prosecution for a violation of subsection (a) of this section:

(1) Except as provided in paragraph (b)(3)b. of this section, the fact that any person charged with violating this section is, or has been, legally entitled to use alcohol or a drug shall not constitute a defense.

(2) a. No person shall be guilty under paragraph (a)(5) of this section when the person has not consumed alcohol prior to or during driving but has only consumed alcohol after the person has ceased driving and only such consumption after driving caused the person to have an alcohol concentration of .08 or more within 4 hours after the time of driving.

b. No person shall be guilty under paragraph (a)(5) of this section when the person’s alcohol concentration was .08 or more at the time of testing only as a result of the consumption of a sufficient quantity of alcohol that occurred after the person ceased driving and before any sampling which raised the person’s alcohol concentration to .08 or more within 4 hours after the time of driving.

(3) a. No person shall be guilty under paragraph (a)(6) of this section when the person has not used or consumed an illicit or recreational drug prior to or during driving but has only used or consumed such drug after the person has ceased driving and only such use or consumption after driving caused the person’s blood to contain an amount of the drug or an amount of a substance or compound that is the result of the use or consumption of the drug within 4 hours after the time of driving.

b. No person shall be guilty under paragraph (a)(6) of this section when the person has used or consumed the drug or drugs detected according to the directions and terms of a lawfully obtained prescription for such drug or drugs.

c. Nothing in this subsection nor any other provision of this chapter shall be deemed to preclude prosecution under paragraph (a)(2) or (a)(3) of this section.

(4) The charging document may allege a violation of subsection (a) of this section without specifying any particular paragraph of subsection (a) of this section and the prosecution may seek conviction under any of the paragraphs of subsection (a) of this section.

(c) For purposes of subchapter III of Chapter 27 of this title and this subchapter, the following definitions shall apply:

(1) “Alcohol concentration of .08 or more” shall mean:

a. An amount of alcohol in a sample of a person’s blood equivalent to .08 or more grams of alcohol per 100 milliliters of blood; or

b. An amount of alcohol in a sample of a person’s breath equivalent to .08 or more grams per 210 liters of breath.

(7) “Illicit or recreational drug” as that phrase is used in paragraph (a)(6) of this section means any substance or preparation that is:

a. Any material, compound, combination, mixture, synthetic substitute or preparation which is enumerated as a Schedule I controlled substance under § 4714 of Title 16; or

b. Cocaine or of any mixture containing cocaine, as described in § 4716(b)(4) of Title 16; or

(8) “Unlawful use or consumption” as that phrase is used in paragraph (a)(6) of this section means that the person used or consumed a drug without legal authority to do so as provided by Delaware law. This Code describes the procedure by which a person may lawfully obtain, use or consume certain drugs. In a prosecution brought under paragraph (a)(6) of this section, the State need not present evidence of a lack of such legal authority. In a prosecution brought under paragraph (a)(6) of this section, if a person claims that such person lawfully used or consumed a drug, it is that person’s burden to show that person has complied with and satisfied the provisions of this Code regarding obtaining, using or consumption of the drug detected.

(d) Whoever is convicted of a violation of subsection (a) of this section shall:

(1) For the first offense, be fined not less than $500 nor more than $1,500 or imprisoned not more than 12 months or both. Any period of imprisonment imposed under this paragraph may be suspended.

(2) For a second offense occurring at any time within 10 years of a prior offense, be fined not less than $750 nor more than $2,500 and imprisoned not less than 60 days nor more than 18 months. The minimum sentence for a person sentenced under this paragraph may not be suspended.

The sentencing court may suspend up to 9 months of any minimum sentence set forth in this paragraph provided, however, that any portion of a sentence suspended pursuant to this paragraph shall include participation in both a drug and alcohol abstinence program and a drug and alcohol treatment program as set forth in paragraph (d)(9) of this section.

(4) For a fourth offense occurring any time after 3 prior offenses, be guilty of a class E felony, be fined not more than $7,000, and imprisoned not less than 2 years nor more than 5 years. The provisions of § 4205(b)(5) or § 4217 of Title 11 or any other statute to the contrary notwithstanding, the first 6 months of the sentence shall not be suspended, but shall be served at Level V and shall not be subject to any early release, furlough or reduction of any kind. The sentencing court may suspend up to 18 months of any minimum sentence set forth in this paragraph provided, however, that any portion of a sentence suspended pursuant to this paragraph shall include participation in both a drug and alcohol abstinence program and a drug and alcohol treatment program as set forth in paragraph (d)(9) of this section.

(5) For a fifth offense occurring any time after 4 prior offenses, be guilty of a class E felony, be fined not more than $10,000 and imprisoned not less than 3 years nor more than 5 years.

No conviction for a violation of this section, for which a sentence is imposed pursuant to this paragraph or paragraph (d)(3) or (d)(4) of this section, shall be considered a predicate felony for conviction or sentencing pursuant to § 4214 of Title 11. No offense for which sentencing pursuant to this paragraph or paragraph (d)(3) or (d)(4) of this section is applicable shall be considered an underlying felony for a murder in the first degree charge pursuant to § 636(a)(2) of Title 11.

(9) Any minimum sentence suspended pursuant to paragraph (d)(3), (d)(4), or (d)(8) of this section shall be upon the condition that the offender shall complete a program of supervision which shall include:

a. A drug and alcohol abstinence program requiring that the offender maintain a period of not less than 90 consecutive days of sobriety as measured by a transdermal continuous alcohol monitoring device or through periodic breath or urine analysis. In addition to such monitoring, the offender shall participate in periodic, random breath or urine analysis during the entire period of supervision.

b. An intensive inpatient or outpatient drug and alcohol treatment program for a period of not less than 3 months. Such treatment and counseling may be completed while an offender is serving a Level V or Level IV sentence.

c. Any other terms or provisions deemed appropriate by the sentencing court or the Department of Correction.

(10) In addition to the penalties otherwise authorized by this subsection, any person convicted of a violation of subsection (a) of this section, committed while a person who has not yet reached the person’s seventeenth birthday is on or within the vehicle shall:

a. For the first offense, be fined an additional minimum of $500 and not more than an additional $1,500 and sentenced to perform a minimum of 40 hours of community service in a program benefiting children.

b. For each subsequent like offense, be fined an additional minimum of $750 and not more than an additional $2,500 and sentenced to perform a minimum of 80 hours of community service in a program benefiting children.

c. Violation of this paragraph shall be considered as an aggravating circumstance for sentencing purposes for a person convicted of a violation of subsection (a) of this section. Nothing in this paragraph shall prevent conviction for a violation of both subsection (a) of this section and any offense as defined elsewhere by the laws of this State.

d. Violation of or sentencing pursuant to this paragraph shall not be considered as evidence of either comparative or contributory negligence in any civil suit or insurance claim, nor shall a violation of or sentencing pursuant to this paragraph be admissible as evidence in the trial of any civil action.

(11) A person who has been convicted of prior or previous offenses of this section, as defined in § 4177B(e) of this title, need not be charged as a subsequent offender in the complaint, information or indictment against the person in order to render the person liable for the punishment imposed by this section on a person with prior or previous offenses under this section. However, if at any time after conviction and before sentence, it shall appear to the Attorney General or to the sentencing court that by reason of such conviction and prior or previous convictions, a person should be subjected to paragraph (d)(3), (d)(4), (d)(5), (d)(6) or (d)(7) of this section, the Attorney General shall file a motion to have the defendant sentenced pursuant to those provisions. If it shall appear to the satisfaction of the court at a hearing on the motion that the defendant falls within paragraph (d)(3), (d)(4), (d)(5), (d)(6) or (d)(7) of this section, the court shall enter an order declaring the offense for which the defendant is being sentenced to be a felony and shall impose a sentence accordingly.

(12) The Court of Common Pleas and Justice of the Peace Courts shall not have jurisdiction over offenses which must be sentenced pursuant to paragraph (d)(3), (d)(4), (d)(5), (d)(6), (d)(7), (d)(8) or (d)(9) of this section.

(13) The Justice of the Peace Court shall have jurisdiction to accept pleas of guilt and to impose sentence for violations of this section that are not subject to sentencing pursuant to paragraphs (d)(3) through (d)(9) of this section and to enter conditional adjudications of guilt requiring or permitting a person to enter a first offender election pursuant to § 4177B of this title. The Justice of the Peace Court shall not have jurisdiction to try any violations of this section. If an offense or criminal case within the exclusive jurisdiction of a justice of the peace or alderman or mayor of any incorporated city or town, except the City of Newark, is or may be joined properly with a violation of this section, such offense or criminal case shall remain joined with any violation of this section for the purpose of trial.

(14) If a person enters a guilty plea in a court of competent jurisdiction to a violation of subsection (a) of this section, such action shall constitute a waiver of the right to an administrative hearing as provided for in § 2742 of this title and shall act to withdraw any request previously made therefor.

(15) Notwithstanding any law to the contrary, the phrase “all crimes” as used in the Truth in Sentencing Act of 1989 shall include felonies under this section, and any amendments thereto.

(e) In addition to any penalty for a violation of subsection (a) of this section, the court shall prohibit the person convicted from operating any motor vehicle unless such motor vehicle is equipped with a functioning ignition interlock device; the terms of installation of the device and licensing of the individual to drive shall be as set forth in § 4177C and § 4177G of this title. A person who is prohibited from operating any motor vehicle unless such motor vehicle is equipped with a functioning ignition interlock device under this title at the time of an offense under subsection (a) of this section shall, in addition to any other penalties provided under law, pay a fine of $2,000 and be imprisoned for 60 days.

(f) In addition to any penalty for a violation of subsection (a) of this section, the court shall order the person to complete an alcohol evaluation and to complete a program of education or rehabilitation pursuant to § 4177D of this title which may include inpatient treatment and be followed by such other programs as established by the treatment facility, not to exceed a total of 15 months and to pay a fee not to exceed the maximum fine; provided however, that successful completion of the Court of Common Pleas Driving Under the Influence Treatment Program shall satisfy this requirement.

(g) For purposes of a conviction premised upon subsection (a) of this section, or any proceeding pursuant to this Code in which an issue is whether a person was driving a vehicle 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 after the time of driving or at some later time. In any proceeding, the resulting alcohol or drug concentration reported when a test, as defined in paragraph (c)(3) of this section, 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.

(1) 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 may only be admissible in proceedings for the determination of guilt when evidence or argument by the defendant is admitted or made relating to the alcohol concentration of the person at the time of driving.

(2) Nothing in this section shall preclude conviction of an offense defined in this Code 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.

(3) A jury shall be instructed by the court in accordance with the applicable provisions of this subsection in any proceeding pursuant to this Code in which an issue is whether a person was driving a vehicle while under the influence of alcohol or drugs or a combination of both.

(h) (1) For the purpose of introducing evidence of a person’s alcohol concentration or the presence or concentration of any drug pursuant to this section, a report signed by the Forensic Toxicologist, 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 Toxicologist, Forensic Chemist or State Police Forensic Analytical Chemist personally appearing in court:

a. That the blood delivered was properly tested under procedures approved by the Division of Forensic Science, or the Delaware State Police Crime Laboratory;

b. That those procedures are legally reliable;

c. That the blood was delivered by the officer or persons stated in the report; and,

d. That the blood contained the alcohol, drugs or both therein stated.

(2) Any report introduced under paragraph (h)(1) of this section must:

a. Identify the Forensic Toxicologist, 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 an 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 that person’s opinion, contains the resulting alcohol concentration or the presence or concentration of any drug within the meaning of this section.

Nothing in this subsection precludes the right of any party to introduce any evidence supporting or contradicting the evidence contained in the report entered pursuant to paragraphs (h)(1) and (2) of this section.

(3) 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.

(4) 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 Toxicologist, 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.

(i) In addition to any other powers of arrest, any law-enforcement officer is hereby authorized to arrest without a warrant any person who the officer has probable cause to believe has violated the provisions of this section, regardless of whether the alleged violation was committed in the presence of such officer. This authority to arrest extends to any hospital or other medical treatment facility located beyond the territorial limits of the officer’s jurisdiction provided there is probable cause to believe that the violation of this section occurred within the officer’s jurisdiction. This authority to arrest also extends to any place where the person is found within 4 hours of the alleged driving of a vehicle if there is reason to believe the person has fled the scene of an accident in which that person was involved, and provided there is probable cause to believe that the violation of this section occurred within the officer’s jurisdiction.

(j) Any court in which a conviction of or guilty plea to a driving under the influence offense shall include the blood alcohol concentration of the defendant (if any is on record) when forwarding notice of said conviction or guilty plea to the Division of Motor Vehicles.
