Payment of the indicated assessment shall operate as a final disposition of the matter. The violator shall not be required to report to any probation officer, and no record of the matter shall be entered in any criminal or probation records of any court. The payment of the indicated assessment shall not be admissible as an admission of guilt, responsibility or negligence in any criminal or civil proceeding, except that such payment shall be an admission of responsibility and shall operate as a conviction for purposes of any action by the registrar pursuant to chapter ninety and for purposes of the safe driver insurance plan established by section one hundred and thirteen B of chapter one hundred and seventy-five.
A violator who does not, within twenty days of the date of the citation, request a noncriminal hearing shall not thereafter be given such a hearing, unless the registrar shall determine that the failure to make such a request timely was for good cause that was not within the control of the violator. The registrar's determination of such issue shall be final.
The registrar shall notify the clerk-magistrate of the district court for the judicial district in which the infraction occurred of such request for a noncriminal hearing, in such manner as the chief justice of the district court department and the registrar shall jointly determine. Unless a hearing date and time has already been assigned pursuant to procedures jointly established by the chief justice of the district court department and the registrar, the clerk-magistrate shall notify the police agency concerned and the violator of the date and time of the hearing before a magistrate of the court.
If the hearing is conducted by a magistrate other than a justice, either the violator or the police agency concerned may appeal the decision of the magistrate to a justice, who shall hear the case de novo. Any violator so appealing the decision of a magistrate shall be responsible for paying a fee of $50 prior to the scheduling of the appeal hearing before a justice. There shall be no right of jury trial for civil motor vehicle infractions.
In any such hearing before a magistrate or justice, the citation shall be admissible and shall be prima facie evidence of the facts stated therein. Compulsory process for witnesses may be had by either party in the same manner as in criminal cases. On a showing of need in advance of such hearing, the magistrate or justice may direct that the violator be permitted to inspect specific written documents or materials in the possession of the police officer or agency concerned that are essential to the violator's defense.
At the conclusion of the hearing, the magistrate or justice shall announce a finding of responsible or not responsible. The magistrate or justice shall enter a finding of responsible if it was shown by a preponderance of the credible evidence that the violator committed the infraction alleged; otherwise the magistrate or justice shall enter a finding of not responsible, which shall be communicated to the registrar. No other disposition shall be permitted, and such matters shall not be continued without a finding, dismissed, or filed.
If the violator is found responsible after a noncriminal hearing, the magistrate or justice shall require the violator to pay to the registrar an assessment which shall not exceed the scheduled assessment for that infraction. Such assessment shall be in accordance with any guidelines promulgated by the chief justice of that department of the trial court, which shall be binding on magistrates and justices, to the end that such assessments are made as uniformly as possible, and which may include provisions requiring a prescribed or a minimum assessment for specified civil motor vehicle infractions.
The violator shall pay to the registrar the assessment imposed by the magistrate or justice within twenty days of the date the violator is personally notified or is mailed notice of the decision of the magistrate or justice, unless for good cause the magistrate or justice allows the violator a longer time to pay the imposed assessment.
The violator's obligation to pay such imposed assessment shall automatically be stayed during the pendency of any timely appeal to the appellate division or any subsequent appeal to an appellate court. The violator shall be required to pay such imposed assessment to the registrar within twenty days of the date the appellate division or the appellate court renders a decision that is adverse to the violator and that has not been further appealed.
Unless such notice is sooner cancelled by the registrar, in the case of an operator violation, such violator's operators license, learners permit or right to operate, or in the case of an owner violation any registration of a motor vehicle issued to such violator by the registrar, shall be deemed suspended by operation of law on the date indicated on the notice mailed by the registrar, and shall remain suspended until reinstated by the registrar upon payment of the scheduled or imposed assessments for such civil motor vehicle infractions, plus any late fees or other administrative fees which the registrar is required or authorized by law or regulation to impose, unless such fees are waived in whole or in part by the registrar.
The citation shall serve as the application for criminal complaint, supplemented if necessary with such additional information as shall be required by the administrative justice of the district court department. If a criminal complaint is issued, the procedure established for criminal cases shall then be followed. Each police chief may, from time to time, designate one person to sign all such complaints.
Upon receipt of such notice, the registrar shall revoke any operators license, learners permit, certificate of registration or title, number plate, sticker, decal or other item issued by the registrar and held by the violator and order the return thereof forthwith. Such violator may not apply for or receive any operators license, learners permit, certificate of registration or title, number plate, sticker, decal or other item issued by the registrar unless and until the violator presents the registrar with a certificate of the clerk-magistrate of the court that the matter has been fully disposed of in accordance with law or, in the case of a matter still pending before the court, that the violator is attending to the matter to the satisfaction of the court. The court shall not unreasonably withhold such certificate. The registrar may cancel such revocation, and so notify the court, if satisfied that it resulted through error of the registrar or the court.
Nothing herein shall limit the availability to the court of other enforcement mechanisms in addition to notice to the registrar, including the issuance of additional written notices, summonses or warrants, including warrants of distress as provided for in section forty-two of chapter two hundred and seventy-nine, or proceedings for civil or criminal contempt. Civil contempt actions shall be prosecuted by the district attorney or police prosecutor and heard by a justice pursuant to rules of court. Any summons or warrant issued pursuant to this subsection may be served by any officer authorized to service criminal process.
The civil motor vehicle infraction shall retain its character as such and shall be decided and disposed of under the same general procedures and with the same provisions as to disposition and assessments as provided in subsection (A), with the following exceptions:
If the violator in such a case defaults solely on the portion of such citation that constitutes one or more civil motor vehicle infractions, such default shall be dealt with as indicated in subsection (A). If the violator in such a case defaults on the portion of such citation that constitutes one or more criminal automobile law violations, such default shall be dealt with as indicated in subsection (B).
