Method and apparatus for warning drivers as to the presence of concealed hazards
First Claim
1. A method for warning drivers as to the presence of a school bus in the process of unloading a passenger, comprising the steps of:
- providing a sign adapted for installation along a highway, the sign having a switch to turn the sign from an inactive mode to a warning mode, the sign has warning lights which are illuminated and flash when the sign is in the warning mode, the sign being normally in the inactive mode, the sign having a receiver which activates the switch to change the sign from the inactive mode to the warning mode upon receiving a signal;
providing a transmitter for sending a signal to the receiver to remotely change the sign from the inactive mode to the warning mode;
positioning the sign at a location along a highway that is visible a sufficient distance from a concealed stopping location to provide drivers of approaching motor vehicles warning as to the presence of a school bus at the concealed stopping location in sufficient time to enable such drivers to stop their motor vehicles in safety; and
positioning the transmitter 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 while the school bus is stopped at the concealed location.

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.
