AUSTIN (KXAN) — One family whose child died after being left in a hot car is hoping their painful lesson will save the lives of others. Now, they have the backing of state leaders.

In 2011, Krisiti Cavaliero’s husband forgot to drop off their little girl, Ray Ray, at day care on his way to work. Since 1990, hundreds of parents have made the same mistake, leading to the deaths of nearly 700 children across the country.

“We decided together to develop a call system called Ray Ray’s Pledge,” said Cavaliero.

Ray Ray’s Pledge aims to make sure the number does not rise. It is dual commitment to safety surrounding that morning day care drop off. The call system would work between the day care and parent. There is also a model with a built-in alert reminding parents to check the backseat.

But Cavaliero said forgetting your child is not the only danger.

“A lot of hot car deaths happen after a child get a hold of car keys,” Cavaliero added. “They get inside the vehicle and then can’t get out.”

Cavaliero never wants this to happen to another parent.

“I think this is a critical first step to hopefully make sure parents aware of this danger,” said Cavaliero.

Information regarding deaths of children left in hot cars will now be mandatory for parents of newborn babies. The new law goes into effect Sept. 1.

Car temps rise fast

It does not take long for a hot car to become a danger zone for children. According to the National Highway Traffic Safety Administration, temperatures inside a car can rise more than 20 degrees in only 10 minutes. Even if it is 60 degrees outside, the car can reach 110 degrees inside.
