When does leaving a child unattended in a vehicle become a third-degree felony?

• When the child is left unattended for more than 30 minutes
• When the child is left unattended without the vehicle's motor running
• When the violation causes great bodily harm to that child
  Explanation:

  "Florida law states that a parent, legal guardian, or other person responsible for a child younger than 6 years of age must not leave the child unattended or unsupervised for any period of time if the motor of the vehicle is running, the health of the child is in danger, or the child appears to be in distress. A violation of this law is a second-degree misdemeanor; a violation that causes great bodily harm, permanent disability, or permanent disfigurement to a child is considered a third-degree felony."
