(a) (1) The throwing, depositing, dropping, releasing, or dumping of litter from a motor vehicle, boat, airplane, or other conveyance in violation of this chapter is prima facie evidence that the operator of the conveyance violated chapter.
(2) If, under paragraph (a)(1) of this section, a motor vehicle is used and the identity of the operator is not discernable, there is a rebuttable presumption that the registered owner of the motor vehicle caused or contributed to the violation.
(b) A license to operate a conveyance listed in paragraph (a)(1) of this section may be suspended for a period not to exceed 30 days together with, or in lieu of, other penalties for littering under this chapter or another law of this State.
