SYSTEM FOR TRANSMITTING A DANGER SIGNAL FOR ROAD VEHICLES

摘要

The invention concerns an alarm device fitted on several road vehicles, permanently warning the drivers of a critical situation, comprising for each vehicle a transceiver radio operating on the same frequency, constantly in receiving position and ready to signal visually and aurally the presence of a transmitter and indicate whether the transceiver distance increases or decreases. The alarm transmitter is operated manually or automatically. The device is for increasing means of communication between road users, presently restricted to flashing alarm lamps, horns and sound radio transmission (CB-channel) and particularly for avoiding chain accidents in foggy weather.
