Don’t leave children or pets in a car while you run an errand – even if it’s just going to be for a few minutes. Temperatures can reach dangerous levels in a matter of minutes. Beat the Heat - Check the Backseat!
On a sunny day a few summers ago, our friends at the National Weather Service Forecast Office near Sullivan, Wisconsin performed an unofficial experiment to determine how quickly an automobile would heat up in directly sunlight. This simplified experiment consisted of putting an electronic thermometer inside a closed automobile (dark blue in color with sun to the rear), and another electronic therometer placed outside of the vehicle to measure ambient temperature in the shade. The interior and exterior readings were compared at timed increments.
The interior of the car was cooled to 83 degrees by the vehicle air conditioner, the engine was turned off and the monitoring was started. After only fifteen minutes the automobile interior heated to a deadly 120 degrees. Many unofficial experiments have been conducted that indicate inside temperatures can rise 35 to 45 degrees above outside temperatures!
Here are the results:

When hot temperatures occur it is important to not leave children or pets in parked vehicles, even for short periods of time, under any circumstances!
Heat kills. In the past dozen years over 450 children have died from hyperthermia after being left in or gaining access to unattended cars!
