Nine years after requests by child safety advocacy groups were initially made, the NHTSA is moving forward with a bill mandating that all vehicles be equipped with safer power window switches, outlawing the popular "rocker" or "toggle" style pictured at right. These switches have been implicated in an estimated 23 child deaths since 1993, as children can accidentally depress the "window up" side while their heads are out of open windows. Most recent switches demand a "pull up" motion to close windows, which is expected to become the standard. The shift is expected to cost car makers less than $100 million, and Big Three automakers predict near full compliance by 2007. Most newer Japanese vehicles already have the safer switches.
