Abstract

A method and apparatus for warning drivers as to the presence of a concealed hazard. A first step involves providing a sign capable of changing from an inactive mode to a warning mode upon receiving a signal. A second step involves providing a transmitter compatible with the signs receiver. A third step involves positioning the sign at a location along a highway that is visible a sufficient distance from the concealed hazard to provide warning to drivers of approaching vehicles. Where the concealed hazard is a concealed school bus stopping location, it is preferred that the transmitter be positioned in a school bus so as to enable a driver of the school bus to remotely change the sign from the inactive mode to the warning mode as the school bus approaches the concealed stopping location.
