Study: Warning devices for hot cars not enough to save children from injury or death

KANSAS CITY, Mo. - New evidence out Tuesday morning shows warning devices alone are not enough to save children from being left in hot cars. A locked car can become deadly quickly for a child and we've all heard of those types of tragedies.

According to the National Highway Traffic Safety Administration, heat stroke killed 33 children in cars last year and 49 the year before.

A new government study finds that consumer products aimed at avoiding these tragedies are not successful on their own.

The research from the government agency and the Children's Hospital of Philadelphia found that new devices intended to help parents avoid such tragedies with child-detecting sensors and alerts are well intended, but unreliable and inconsistent when used on their own.

Some became ineffective by cell phone interference, others when children moved out of position. Experts fear the devices give parents a false sense of security.

While manufacturers work on improving technologies here are some safety tips:

-- Never leave children unattended in a vehicle, even for a few minutes.

-- Check the front and back of the vehicle before locking and walking away.

-- Give yourself reminders; place a bag, briefcase, or cell phone in the back seat if you need to.

-- Teach children that the car isn't a play area.

There is a Kansas City organization dedicated to helping parents.
