No, because this is Florida state statute 316.613 regarding child restraint seats in a moving vehicle being operated on roadways, streets or highways of the state of Florida. Appropriate sections of the statute are stated below.Note that Sections (1)(a) and (2) state that the vehicle must be in operation on a street, roadway or highway. A motor vehicle that is parked on private property is not being operated on a street, roadway or highway. Thus the statute does not apply to cars parked on private property.Section (5) states that the offense shall be deemed a moving offense. This gives rise to the presumption that the statute must refer only to a car that is moving rather than parked. The presumption is most likely irrebuttable."316.613 Child restraint requirements.--(1)(a) Every operator of a motor vehicle as defined herein, while transporting a child in a motor vehicle operated on the roadways, streets, or highways of this state, shall, if the child is 5 years of age or younger, provide for protection of the child by properly using a crash-tested, federally approved child restraint device. For children aged through 3 years, such restraint device must be a separate carrier or a vehicle manufacturer's integrated child seat. For children aged 4 through 5 years, a separate carrier, an integrated child seat, or a seat belt may be used.. . .(2) As used in this section, the term "motor vehicle" means a motor vehicle as defined in s. 316.003 that is operated on the roadways, streets, and highways of the state.. . .(5) Any person who violates the provisions of this section commits a moving violation, punishable as provided in chapter 318 and shall have 3 points assessed against his or her driver's license as set forth in s. 322.27."
