(a) Any person who operates a motor vehicle in this state shall be deemed to have given his consent to a chemical analysis of his blood, breath or urine and, if said person is a minor, his parent or parents or guardian shall also be deemed to have given his consent.

(b) If any such person, having been placed under arrest for operating a motor vehicle while under the influence of intoxicating liquor or any drug or both or while his ability to operate such motor vehicle is impaired by the consumption of intoxicating liquor, and thereafter, after being apprised of his constitutional rights, having been requested to submit to a blood, breath or urine test at the option of the police officer, having been afforded a reasonable opportunity to telephone an attorney prior to the performance of such test and having been informed that his license or nonresident operating privilege may be suspended in accordance with the provisions of this section if he refuses to submit to such test or if he submits to such test and the results of such test indicate that the ratio of alcohol in his blood was ten-hundredths of one per cent or more of alcohol, by weight, and that evidence of any such refusal shall be admissible in accordance with subsection (f) of section 14-227a and may be used against him in any criminal prosecution, refuses to submit to the designated test, the test shall not be given; provided, if the person refuses or is unable to submit to a blood test, the police officer shall designate the breath or urine test as the test to be taken. The police officer shall make a notation upon the records of the police department that he informed the person that his license or nonresident operating privilege may be suspended if he refused to submit to such test or if he submitted to such test and the results of such test indicated that the ratio of alcohol in his blood was ten-hundredths of one per cent or more of alcohol, by weight

(c) If the person arrested refuses to submit to such test or analysis or submits to such test or analysis, commenced within two hours of the time of operation, and the results of such test or analysis indicate that the ratio of alcohol in the blood of such person is ten-hundredths of one per cent or more of alcohol, by weight, the police officer, acting on behalf of the Commissioner of Motor Vehicles, shall immediately revoke and take possession of the motor vehicle operator's license or, if such person is a nonresident, suspend the nonresident operating privilege of such person, for a twenty-four-hour period and shall issue a temporary operator's license or nonresident operating privilege to such person valid for the period commencing twenty-four hours after issuance and ending thirty days after the date such person received notice of his arrest by the police officer. The police officer shall prepare a written report of the incident and shall mail the report together with a copy of the completed temporary license form, any operator's license taken into possession and a copy of the results of any chemical test or analysis to the Department of Motor Vehicles within three business days. The report shall be made on a form approved by the Commissioner of Motor Vehicles and shall be subscribed and sworn to under penalty of false statement as provided in section 53a-157b by the arresting officer. If the person arrested refused to submit to such test or analysis, the report shall be endorsed by a third person who witnessed such refusal. The report shall set forth the grounds for the officer's belief that there was probable cause to arrest such person for operating a motor vehicle while under the influence of intoxicating liquor or any drug or both or while his ability to operate such motor vehicle is impaired by the consumption of intoxicating liquor, and shall state that such person had refused to submit to such test or analysis when requested by such police officer to do so or that such person submitted to such test or analysis, commenced within two hours of the time of operation, and the results of such test or analysis indicated that the ratio of alcohol in the blood of such person was ten-hundredths of one per cent or more of alcohol, by weight.

(d) If the person arrested submits to a blood or urine test at the request of the police officer, and the specimen requires laboratory analysis in order to obtain the test results, the police officer shall not take possession of the motor vehicle operator's license of such person or, except as provided in this subsection, follow the procedures subsequent to taking possession of the operator's license as set forth in subsection (c) of this section. If the test results indicate that the ratio of alcohol in the blood of such person was ten-hundredths of one per cent or more of alcohol, by weight, the police officer, immediately upon receipt of the test results, shall notify the Commissioner of Motor Vehicles and submit to the commissioner the written report required pursuant to subsection (c) of this section.

(e) Upon receipt of such report, the Commissioner of Motor Vehicles may suspend any license or nonresident operating privilege of such person effective as of a date certain, which date shall be not later than thirty days after the date such person received notice of his arrest by the police officer. Any person whose license or operating privilege has been suspended in accordance with this subsection shall automatically be entitled to a hearing before the commissioner to be held prior to the effective date of the suspension. The commissioner shall send a suspension notice to such person informing such person that his operator's license or nonresident operating privilege is suspended as of a date certain and that he is entitled to a hearing prior to the effective date of the suspension and may schedule such hearing by contacting the Department of Motor Vehicles not later than seven days after the date of mailing of such suspension notice.

(f) If such person does not contact the department to schedule a hearing, the commissioner shall affirm the suspension contained in the suspension notice for the appropriate period specified in subsection (i) of this section.

(g) If such person contacts the department to schedule a hearing, the department shall assign a date, time and place for the hearing, which date shall be prior to the effective date of the suspension. At the request of such person or the hearing officer and upon a showing of good cause, the commissioner may grant one continuance for a period not to exceed fifteen days. If a continuance is granted, the commissioner shall extend the validity of the temporary operator's license or nonresident operating privilege issued pursuant to subsection (c) of this section for a period not to exceed the period of such continuance. The hearing shall be limited to a determination of the following issues: (1) Did the police officer have probable cause to arrest the person for operating a motor vehicle while under the influence of intoxicating liquor or drug or both or while his ability to operate such motor vehicle was impaired by the consumption of intoxicating liquor; (2) was such person placed under arrest; (3) did such person refuse to submit to such test or analysis or did such person submit to such test or analysis, commenced within two hours of the time of operation, and the results of such test or analysis indicated that the ratio of alcohol in the blood of such person was ten-hundredths of one per cent or more of alcohol, by weight; and (4) was such person operating the motor vehicle. In the hearing, the results of the test or analysis shall be sufficient to indicate the ratio of alcohol in the blood of such person at the time of operation, except that if the results of the additional test indicate that the ratio of alcohol in the blood of such person is twelve-hundredths of one per cent or less of alcohol, by weight, and is higher than the results of the first test, evidence shall be presented that demonstrates that the test results and analysis thereof accurately indicate the blood alcohol content at the time of operation. The fees of any witness summoned to appear at the hearing shall be the same as provided by the general statutes for witnesses in criminal cases.

(h) If, after such hearing, the commissioner finds on any one of the said issues in the negative, the commissioner shall reinstate such license or operating privilege. If, after such hearing, the commissioner does not find on any one of the said issues in the negative or if such person fails to appear at such hearing, the commissioner shall affirm the suspension contained in the suspension notice for the appropriate period specified in subsection (i) of this section. The commissioner shall render a decision at the conclusion of such hearing or send a notice of his decision by bulk certified mail to such person not later than thirty days or, if a continuance is granted, not later than forty-five days from the date such person received notice of his arrest by the police officer. The notice of such decision sent by certified mail to the address of such person as shown by the records of the commissioner shall be sufficient notice to such person that his operator's license or nonresident operating privilege is reinstated or suspended, as the case may be. Unless a continuance of the hearing is granted pursuant to subsection (g) of this section, if the commissioner fails to render a decision within thirty days from the date such person received notice of his arrest by the police officer, the commissioner shall reinstate such person's operator's license or nonresident operating privilege, provided notwithstanding such reinstatement the commissioner may render a decision not later than two days thereafter suspending such operator's license or nonresident operating privilege.

(i) The commissioner shall suspend the operator's license or nonresident operating privilege, and revoke the temporary operator's license or nonresident operating privilege issued pursuant to subsection (c) of this section, of a person who did not contact the department to schedule a hearing, who failed to appear at a hearing or against whom, after a hearing, the commissioner held pursuant to subsection (h) of this section, as of the effective date contained in the suspension notice or the date the commissioner renders his decision, whichever is later, for a period of: (1) (A) Ninety days, if such person submitted to a test or analysis and the results of such test or analysis indicated that the ratio of alcohol in the blood of such person was ten-hundredths of one per cent or more of alcohol, by weight, or (B) six months if such person refused to submit to such test or analysis, (2) one year if such person has previously had his operator's license or nonresident operating privilege suspended under this section, and (3) two years if such person has two or more times previously had his operator's license or nonresident operating privilege suspended under this section.

(j) Notwithstanding the provisions of subsections (b) to (i), inclusive, of this section, any police officer who obtains the results of a chemical analysis of a blood sample taken from an operator of a motor vehicle involved in an accident who suffered or allegedly suffered physical injury in such accident shall notify the Commissioner of Motor Vehicles and submit to the commissioner a written report if such results indicate that the ratio of alcohol in the blood of such person was ten-hundredths of one per cent or more of alcohol, by weight, and if such person was arrested for violation of section 14-227a in connection with such accident. The report shall be made on a form approved by the commissioner containing such information as the commissioner prescribes, and shall be subscribed and sworn to under penalty of false statement, as provided in section 53a-157b, by the police officer. The commissioner may, after notice and an opportunity for hearing, which shall be conducted in accordance with chapter 54, suspend the motor vehicle operator's license or nonresident operating privilege of such person for a period of up to ninety days, or, if such person has previously had his operator's license or nonresident operating privilege suspended under this section for a period of up to one year. Each hearing conducted under this subsection shall be limited to a determination of the following issues:

(1) Whether the police officer had probable cause to arrest the person for operating a motor vehicle while under the influence of intoxicating liquor or drug or both or while the person's ability to operate the motor vehicle was impaired by the consumption of intoxicating liquor;
(2) whether such person was placed under arrest;
(3) whether such person was operating the motor vehicle;
(4) whether the results of the analysis of the blood of such person indicate that the ratio of alcohol in such person's blood was ten-hundredths of one per cent or more of alcohol, by weight; and
(5) whether the blood sample was obtained in accordance with conditions for admissibility and competence as evidence as set forth in subsection (l) of section 14-227a. If, after such hearing, the commissioner finds on any one of the said issues in the negative, the commissioner shall not impose a suspension. The fees of any witness summoned to appear at the hearing shall be the same as provided by the general statutes for witnesses in criminal cases, as provided in section 52-260.

(k) The provisions of this section shall apply with the same effect to the refusal by any person to submit to an additional chemical test as provided in subdivision (5) of subsection (c) of section 14-227a.

(l) The provisions of this section shall not apply to any person whose physical condition is such that, according to competent medical advice, such test would be inadvisable.

(m) The state shall pay the reasonable charges of any physician who, at the request of a municipal police department, takes a blood sample for purposes of a test under the provisions of this section.

(n) The Commissioner of Motor Vehicles shall adopt regulations in accordance with chapter 54 to implement the provisions of this section.
