Abstract: A road hazard warning system provides a remote control and/or a turn signal-like on-steering wheel activation and engagement device, connected through an electronic interface, to cause a remote device to display a user-selected road hazard message. The device employs a CANCEL or OFF button on the remote control, or neutral position in an on-steering column stalk implementation, and/or an automatic cancellation feature after a given default time period, which provides for the cancellation of the currently-selected hazard and returns the display to a default state.
