Implied Consent

California Vehicle Code Section 23612

23612. (a) (1) (A) A person who drives a motor vehicle is deemed to have given his or her consent to chemical testing of his or her blood or breath for the purpose of determining the alcoholic content of his or her blood, if lawfully arrested for an offense allegedly committed in violation of Section 23140, 23152, or 23153. If a blood or breath test, or both, are unavailable, then paragraph (2) of subdivision (d) applies.

(B) A person who drives a motor vehicle is deemed to have given his or her consent to chemical testing of his or her blood or urine for the purpose of determining the drug content of his or her blood, if lawfully arrested for an offense allegedly committed in violation of Section 23140, 23152, or 23153.

(C) The testing shall be incidental to a lawful arrest and administered at the direction of a peace officer having reasonable cause to believe the person was driving a motor vehicle in violation of Section 23140, 23152, or 23153.

(D) The person shall be told that his or her failure to submit to, or the failure to complete, the required chemical testing will result in a fine, mandatory imprisonment if the person is convicted of a violation of Section 23152 or 23153, and (i) the suspension of the person's privilege to operate a motor vehicle for a period of one year, (ii) the revocation of the person's privilege to operate a motor vehicle for a period of two years if the refusal occurs within 10 years of a separate violation of Section 23103 as specified in Section 23103.5, or of Section 23140, 23152, or 23153, or of Section 191.5 or subdivision (a) of Section 192.5 of the Penal Code that resulted in a conviction, or if the person's privilege to operate a motor vehicle has been suspended or revoked pursuant to Section 13353, 13353.1, or 13353.2 for an offense that occurred on a separate occasion, or (iii) the revocation of the person's privilege to operate a motor vehicle for a period of three years if the refusal occurs within 10 years of two or more separate violations of Section 23103 as specified in Section 23103.5, or of Section 23140, 23152, or 23153, or of Section 191.5 or subdivision (a) of Section 192.5 of the Penal Code, or any combination thereof, that resulted in convictions, or if the person's privilege to operate a motor vehicle has been suspended or revoked two or more times pursuant to Section 13353, 13353.1, or 13353.2 for offenses that occurred on separate occasions, or if there is any combination of those convictions or administrative suspensions or revocations.

(2) (A) If the person is lawfully arrested for driving under the influence of an alcoholic beverage, the person has the choice of whether the test shall be of his or her blood or breath and the officer shall advise the person that he or she has that choice. If the person arrested either is incapable, or states that he or she is incapable, of completing the chosen test, the person shall submit to the remaining test. If a blood or breath test, or both, are unavailable, then paragraph (2) of subdivision (d) applies.

(B) If the person is lawfully arrested for driving under the influence of any drug or the combined influence of an alcoholic beverage and any drug, the person has the choice of whether the test shall be of his or her blood, breath, or urine, and the officer shall advise the person that he or she has that choice.

(C) A person who chooses to submit to a breath test may also be requested to submit to a blood or urine test if the officer has reasonable cause to believe that the person was driving under the influence of a drug or the combined influence of an alcoholic beverage and a drug and if the officer has a clear indication that a
blood or urine test will reveal evidence of the person being under the influence. The officer shall state in his or her report the facts upon which that belief and that clear indication are based. The person has the choice of submitting to and completing a blood or urine test, and the officer shall advise the person that he or she is
required to submit to an additional test and that he or she may choose a test of either blood or urine. If the person arrested either is incapable, or states that he or she is incapable, of completing either chosen test, the person shall submit to and complete the other remaining test.

(3) If the person is lawfully arrested for an offense allegedly committed in violation of Section 23140, 23152, or 23153, and, because of the need for medical treatment, the person is first transported to a medical facility where it is not feasible to administer a particular test of, or to obtain a particular sample of, the person's blood, breath, or urine, the person has the choice of those tests that are available at the facility to which that person has been transported. In that case, the officer shall advise the person of those tests that are available at the medical facility and that the person's choice is limited to those tests that are available.

(4) The officer shall also advise the person that he or she does not have the right to have an attorney present before stating whether he or she will submit to a test or tests, before deciding which test or tests to take, or during administration of the test or tests chosen, and that, in the event of refusal to submit to a test or
tests, the refusal may be used against him or her in a court of law.

(5) A person who is unconscious or otherwise in a condition rendering him or her incapable of refusal is deemed not to have withdrawn his or her consent and a test or tests may be administered whether or not the person is told that his or her failure to submit to, or the noncompletion of, the test or tests will result in the suspension or revocation of his or her privilege to operate a motor vehicle. A person who is dead is deemed not to have withdrawn his or her consent and a test or tests may be administered at the direction of a peace officer.

(b) A person who is afflicted with hemophilia is exempt from the blood test required by this section.

(c) A person who is afflicted with a heart condition and is using an anticoagulant under the direction of a licensed physician and surgeon is exempt from the blood test required by this section.

(d) (1) A person lawfully arrested for an offense allegedly committed while the person was driving a motor vehicle in violation of Section 23140, 23152, or 23153 may request the arresting officer to have a chemical test made of the arrested person's blood or breath for the purpose of determining the alcoholic content of that person's blood, and, if so requested, the arresting officer shall have the test performed.

(2) If a blood or breath test is not available under subparagraph (A) of paragraph (1) of subdivision (a), or under subparagraph (A) of paragraph (2) of subdivision (a), or under paragraph (1) of this subdivision, the person shall submit to the remaining test in order to determine the percent, by weight, of alcohol in the person's blood. If both the blood and breath tests are unavailable, the person shall be deemed to have given his or her consent to chemical testing of his or her urine and shall submit to a urine test.

(e) If the person, who has been arrested for a violation of Section 23140, 23152, or 23153, refuses or fails to complete a chemical test or tests, or requests that a blood or urine test be taken, the peace officer, acting on behalf of the department, shall serve the notice of the order of suspension or revocation of the person's privilege to operate a motor vehicle personally on the arrested person. The notice shall be on a form provided by the
department.

(f) If the peace officer serves the notice of the order of suspension or revocation of the person's privilege to operate a motor vehicle, the peace officer shall take possession of all driver's licenses issued by this state that are held by the person. The temporary driver's license shall be an endorsement on the notice of the order of suspension and shall be valid for 30 days from the date of arrest.

(g) (1) The peace officer shall immediately forward a copy of the completed notice of suspension or revocation form and any driver's license taken into possession under subdivision (f), with the report required by Section 13380, to the department. If the person submitted to a blood or urine test, the peace officer shall forward the
results immediately to the appropriate forensic laboratory. The forensic laboratory shall forward the results of the chemical tests to the department within 15 calendar days of the date of the arrest.

(2) (A) Notwithstanding any other provision of law, a document containing data prepared and maintained in the governmental forensic laboratory computerized database system that is electronically transmitted or retrieved through public or private computer networks to or by the department is the best available evidence of the chemical test results in all administrative proceedings conducted by the department. In addition, any other official record that is maintained in the governmental forensic laboratory, relates to a chemical test analysis prepared and maintained in the governmental forensic laboratory computerized database system, and is electronically transmitted and retrieved through a public or private computer network to or by the department is admissible as evidence in the department's administrative proceedings. In order to be admissible as evidence in administrative proceedings, a document described in this subparagraph shall bear a certification by the employee of the department who retrieved the document certifying that the information was received or retrieved directly from the computerized database system of a governmental forensic laboratory and that the document accurately reflects the data received or retrieved.

(B) Notwithstanding any other provision of law, the failure of an employee of the department to certify under subparagraph (A) is not a public offense.

(h) A preliminary alcohol screening test that indicates the presence or concentration of alcohol based on a breath sample in order to establish reasonable cause to believe the person was driving a vehicle in violation of Section 23140, 23152, or 23153 is a field sobriety test and may be used by an officer as a further investigative tool.

(i) If the officer decides to use a preliminary alcohol screening test, the officer shall advise the person that he or she is requesting that person to take a preliminary alcohol screening test to assist the officer in determining if that person is under the influence of alcohol or drugs, or a combination of alcohol and drugs.
The person's obligation to submit to a blood, breath, or urine test, as required by this section, for the purpose of determining the alcohol or drug content of that person's blood, is not satisfied by the person submitting to a preliminary alcohol screening test. The officer shall advise the person of that fact and of the person's
right to refuse to take the preliminary alcohol screening test.
