This week the National Highway Traffic Safety Administration is trying to raise attention to the risks of heatstroke death or injury, especially for kids who are accidentally locked in a vehicle.

Nationwide this year, 24 children have died after being locked in a car, according to the NHTSA.

Heatstroke can set in more quickly for children locked in a hot environment, the agency reported, because a child's body temperature can rise quicker than an adult's. It can be deadly, but it some cases cause permanent disability, including hearing loss and blindness.

“It’s important never to leave your child unsupervised, even just for a minute in a vehicle," said Valerie Vineyard, a spokeswoman for AAA Arizona. "Temperatures, even on a mild day...can rise 20 degrees in a car in a matter of minutes.”

AAA responds to thousands of calls for dead batteries and lockouts in August, she said.

"The safety risk increases exponentially because of the excessive heat in (that month)," Vineyard said.

The agency offers roadside assistance to stranded drivers, but advises against people calling a similar service if there is a child or animal locked inside a vehicle. In those cases, Vineyard said, people should call 911 for emergency response to a life-threatening situation.
