I live in Florida. We have a law.
Is it illegal to leave a child in a running car in Florida?
(1) A parent, legal guardian, or other person responsible for a child younger than 6 years of age may not leave such child unattended or unsupervised in a motor vehicle: (a) For a period in excess of 15 minutes; (b) For any period of time if the motor of the vehicle is running or the health of the child is in danger.
