Pediatric Vehicular Heatstroke Dangers in Texas

Prevent Hot Car Deaths in Texas


What is hyperthermia?

Hyperthermia is a group of heat illnesses like heat exhaustion and heatstroke. Heatstroke is when the body overheats and is unable to cool itself quickly enough. Heatstroke is the most severe form of hyperthermia. According to the American Academy of Pediatrics (AAP), once a body’s temperature reaches 104 degrees, major organs begin to shut down.

Facts about hot cars and heatstroke

Heatstroke is the leading cause of non-crash, vehicle-related deaths in children younger than age 15.

  • A child's body heats up three to five times faster than an adult's does.
  • Cars heat up quickly! In 10 minutes, a car can heat up 20 degrees.
  • Cracking a window or air conditioning does little to keep the car cool once it is turned off.  

What you should know about pediatric heatstroke in Texas

Texas is one of two states with the highest number of hot car deaths in children. As of 08/14/2023, the National Safety Council reported 16 deaths across the country, three in Texas. The top three circumstances:

  • Caregiver forgot the child;
  • Child gained access on their own; and
  • Caregiver knowingly left the child in the car.

Texas Law

Leaving a Child in a Vehicle (Penal Code Chapter 22.10) - A person commits an offense if he (or she) intentionally or knowingly leaves a child in a motor vehicle for longer than five minutes knowing that the child is:

  • Younger than age 7; and
  • Not attended by an individual in the vehicle who is age 14 or older.  

Tips for caregivers  

  • Teach children not to play in or around cars.
  • Never leave a child unattended in or around a car. Make a habit of looking in the front and back seat of the car before locking the door and walking away.
  • Never assume it can't happen to you or your child. A change in routine or busy schedule can cause a caregiver to forget that a child is still in the car.
  • If you cannot find a child, check the pool and water sources first, then check vehicles, including trunks.
  • If you see an unattended child in or around a car, call 911.
