The bill that was just introduced proposes to require car manufacturers to install an alert system to remind parents that a child may still be seated in the back. A similar bill stalled in committee last year. If this bill was passed it would still take several years for changes to be implemented.
Some manufacturers however have already started to offer to options to prevent them from leaving their child in the back seat. The company evenflo now has car seats equipped with sensors that will remind the driver that a child is in the car seat when the car engine is turned off (see video below). Many cases of children dying in hot cars have been reported after children entered a car and locked themselves in it. The new line of General Motors Acadia SUV is equipped with an alert that will go on if a back door is open before the vehicle is started.
Neither of the new technologies mentioned above would, however, protect children who are intentionally left by parents who think its safe to just leave the child sleeping in the back seat for a few minutes.
