A vehicle warning system is for use with a vehicle having an air horn (30) and a vehicle speed sensor (19) which provides a vehicle speed signal to a vehicle data bus (20). The vehicle warning system has at least one brake pressure sensor (22) to provide a brake pressure signal, an air valve (26), and a controller (24). The controller determines that the brake pressure signal indicates an excessive brake pressure and that the vehicle speed signal indicates an excessive vehicle speed, and opens the air valve to activate the air horn. The controller may read the vehicle speed from the vehicle data bus at periodic intervals or when it determines that there is an excessive brake pressure. The brake pressure is considered to be excessive if it exceeds a brake pressure threshold. The vehicle speed is considered to be excessive if it exceeds a vehicle speed threshold.
