The summer heat is on.
That means an extra danger for children left inside hot cars.
Just since May, 20 children across the country have died, after someone left them alone in a vehicle.
Safe Kids is again spreading the message that parents and caregivers should never leave a child in a car.
The group is offering a new window decal to remind drivers to check the back seat for a child.
It's one of several techniques that can help prevent a child from dying of heat stroke.
Safe Kids Roanoke Coordinator Jill Lucas Drakeford says drivers can also put a purse or cell phone in the back seat, just to make sure they look back there. That can prevent them from forgetting a child is in the vehicle.
The temperature inside a vehicle can heat up quickly. The Safe Kids Web site has a simulation that shows just how hot cars can get.
