In any prosecution for which a summons charging a violation of this section was issued within 30 business days of the alleged violation, proof that the motor vehicle described in the summons was operated in violation of this section, together with proof that the defendant was at the time of such violation the registered owner of the vehicle, as required by Chapter 6 (§ 46.2-600 et seq.) shall give rise to a rebuttable presumption that the registered owner of the vehicle was the person who operated the vehicle at the place where, and for the time during which, the violation occurred. Such presumption shall be rebutted if (i) the owner of the vehicle files an affidavit by regular mail with the clerk of the general district court that he was not the operator of the vehicle at the time of the alleged violation, (ii) the owner testifies in open court under oath that he was not the operator of the vehicle at the time of the alleged violation, or (iii) a certified copy of a police report showing that the vehicle had been reported to the police as stolen prior to the time of the alleged violation of this section is presented prior to the return date established on the summons issued pursuant to this section to the court adjudicating the alleged violation. Nothing herein shall limit the admission of otherwise admissible evidence.
The testimony of the school bus driver, the supervisor of school buses, or a law-enforcement officer that the vehicle was yellow, conspicuously marked as a school bus, and equipped with warning devices as prescribed in § 46.2-1090 is prima facie evidence that the vehicle is a school bus.
Recorded images from a video-monitoring system that show the bus was stopped with at least one warning device prescribed in § 46.2-1090 activated shall be considered prima facie evidence that the bus was stopped for the purpose of taking on or discharging children, elderly individuals, or individuals with mental or physical disabilities.
