The secondary seat belt warning system also includes a control module to activate the seat belt indicator in response to the input from the ignition switch and seat belt sensor. The secondary seat belt warning system further includes a vehicle speed sensor to activate the secondary seat belt warning system when the control module receives a signal above a predetermined threshold from the speed sensor indicative of the vehicle speed.
