Never leave children, disabled adults or pets in parked vehicles!

Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia, which occurs when the body absorbs more heat than it can handle. Hyperthermia can occur even on a mild day with temperatures in the 70s. Studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. The younger the child the more severe the effects because their bodies have not developed the ability to efficiently regulate its internal temperature.

How fast can the sun heat a car?


The sun's shortwave radiation (yellow in figure below) heats objects that it strikes.  For example, a dark dashboard or seat can easily reach temperatures in the range of 180 to over 200°F. These objects (e.g., dashboard, steering wheel, child seat) heat the adjacent air by conduction and convection and also give off longwave radiation (red in figure below) which is very efficient at warming the air trapped inside a vehicle. Shown below are time lapse photos of thermometer readings in a car over a period of less than an hour. As the animation shows, in just over 2 minutes the car went from a safe temperature to an unsafe temperature of 94.3°F. This demonstration shows just how quickly a vehicle can become a death trap for a child.

Safety Tips for Parents



Even on mild days in the 70s, studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. The effects are more severe on children because their bodies warm at a faster rate than adults. A dark dashboard or car-seat can quickly reach temperatures in the range of 180°F to over 200°F. These objects heat the adjacent air by conduction and convection and also give off long wave radiation, which then heats the air trapped inside a vehicle. Follow these tips to ensure your child's safety.

  • Touch a child's safety seat and safety belt before using it to ensure it's not too hot before securing a child
  • Never leave a child unattended in a vehicle, even with the windows down, even for just a minute
  • Teach children not to play in, on, or around cars. They could accidentally trap themselves in a hot vehicle.
  • Always lock car doors and trunks--even at home--and keep keys out of children's reach.
  • Always make sure children have left the car when you reach your destination. Don't leave sleeping infants in the car ever.

Heat deaths in autumn, winter and spring

Hyperthermia deaths aren't confined to summer months. They also happen during the spring and fall. Below are just a few of MANY tragedies.

  • North Augusta, SC, April: A mother left her a 15-month-old son in a car. He was in a car for 9 hours while his mom went to work. She is now serving a 20-year prison sentence.
  • Honolulu, HI, March: A 3-year-old girl died when the father left her in a child seat for 1.5 hours while he visited friends in a Waikiki apartment building. The outside temperature was only 81 degrees.
  • Greenville, TX, December: A 6-month-old boy died after being left in a car for more than 2 hours by his mother. She was charged with murder. The temperature rose to 81 degrees on that day.
Adults also are susceptible to hyperthermia in vehicles. On July 12, 2001, a man died of heat stroke after falling asleep in his car with the windows rolled up in the parking lot of a supermarket in Hinds County, MS.
