Final answer:
Laws about leaving children alone in a parked car with the engine running vary by location, with minimum ages typically between 6 and 12 years old. Local laws should be checked to ensure compliance and understanding that leaving a child unattended in a vehicle poses significant risks.
Step-by-step explanation:
It is against the law to leave children under a certain age alone in a parked car with the engine running. The specific age can vary depending on the state or region's laws and regulations. Many states in the U.S. have laws that set the minimum age typically between 6 and 12 years old. However, there are various factors to consider such as the amount of time the child is left in the car, the weather conditions, and if the child has access to the keys or is in any potential danger. It is important to be aware of the local laws and to never leave a child unattended in a vehicle as it poses significant risks including abduction, injury, or death due to environmental conditions such as heatstroke.
