15. If, during the lower sequence, both red road lights on any RTL are failed before the point in the sequence that the barriers are due to start lowering, then the barriers shall remain in the raised position. In this situation, the barriers can only be lowered from the local control unit until the fault is rectified. Once the barriers have begun to lower a further red light failure shall not stop or prevent them lowering.
